Why are Mill Stand A Necessary To Your Rolling Mill?

 

Mill stands are one of the most crucial pieces of equipment in the entire rolling mill process. A mill stand is usually fit with numerous rolls via which the workpiece bar goes through, achieving its necessary cross-section. Several mill stand designs serve different purposes in the rolling process.

Housing-less Mill Stand 

A Housing-less mill stand is specifically designed to create superior quality TMT bars, wire rods, channels, bars, universal beams, angles and more. The housing-less mill stand can do this effortlessly due to its rigidity and roll change abilities. These mill stands are usually also equipped with complete automation, especially during the connection and disconnection of fluid utilities and spindles. This automation assists the mill stand in becoming more efficient and quick in comparison to others. Housing-less mill stands also have a reduced stress path, screw-down automation, axial roll adjustment abilities along with complete automation, self-balancing spindle and reduced backlash. Roll change is easier in the same.

2-HI Conventional Mill Stand 

A 2-HI conventional mill stand has two work rolls that are pressed together with enormous force. The 2-HI mill stand contains non-reversing rolls that rotate in the same direction, which means that the workpiece bar cannot be fed from the other direction. A 2-HI stand either has to be a vertical or a horizontal stand.

3-HI Conventional Mill Stand 

A 3-HI mill stand is essentially needed in hot rolling reversing mills without switching the order of rotation of the rolls. In this type of mill stand, there are three working rolls. The top and bottom roll rotate in the same direction; meanwhile, the centre roll turns in the opposite direction. This is important as the workpiece bar keeps passing back and forth alternately through the rolls without reversing the direction in which the roll turns.

Pre-Stressed Mill Stand

Pre-stressed mill stands are different from conventional mill stands. In this case, the mill is already pre-stressed with the help of hydraulic four nuts. This allows them to be prepared with the highest force needed for rolls operating during the rolling period. The process allows any deflection of the mill stand to be avoided, especially under the rolling load.

Universal Mill Stand

A universal mill stand is a rolling stand that rolls in four ways. It is used in the rolling section where the section is shaped from all four sides. There are two vertically and horizontally mounted rolls in a universal mill stand. The vertical rolls are inactive and are positioned amid the bearing chocks of the horizontal rolls in the vertical plane. The vertical rolls are essentially present to manage the width of the bar during the rolling process.

Convertible Stands

Convertible mill stands allow conversion in the positioning. The stand allows either vertical or horizontal positioning during the intermediate finishing, depending on the production requirements. Convertible mill stands are convenient due to their speed during changing positions. It takes less than two minutes to do so. The stand rigidity is also an added advantage. The quick stand change system also does require any crane support and is equipped with reduced fountain depth.

Cantilever Stand

A cantilever stand is quite similar to a block mill, has both horizontal and vertical configurations, and can be configured to meet the client’s design requirements. The sleeve bearing on which the rolls are mounted can achieve high speeds and produce wire rods ranging from 5.5mm to 8mm.  The rolls are essentially small discs placed on the cantilever shafts and are available for one or two passes. The material o the roll is often hard and is created out of tungsten carbide.

Vertical Mill Stand

This up-drive type comprises a roll stand, mill spindles, a vertical gear reducer, a pinion stand, and a motor. To protect them from the roll cooling water and mill scale, the gear reducer and motor are installed on a concrete frame. There is also a lifting device under the roll stand that is installed to manage the position of the caliber to pass the level. The roll stand can be moved to the work side during stand changing.

Horizontal Mill Stand

The horizontal mill stand comprises of a roll stand, mill spindles, a pinion stand, a gear reducer and a motor. In the case of a regular pass line, the roll stand slides on the exterior of the sole plate. In a low-speed rolling mill with less than 10 m/sec, the pinion stand and gear reducer are from a single unit. A cross pin joint is used for the mill spindle and is supported by the spindle carrier during rolling.

Bottom line

In a rolling mill, rolling mill stands are used for several purposes, including generating billets, slabs, blooms, bars, plates and other sheet products. Rolling mill stands were initially used for steel casting, but today they are usually created from cast slabs or rolled plates.

How to Reduce the Operating Cost of Rolling Mills

 

India has been growing rapidly when it comes to the steel industry. In comparison to other countries, India rightfully caters to the world’s needs with its high-quality steel solutions. Nowadays, manufacturers have only one goal in mind, which is to provide only superior quality products to their customers.

But how can one achieve that level of quality? It is simply to install state-of-the-art machinery to give attention to detail and produce better quality products. However, what often stops multiple companies from doing so is the cost of operation. Let us find out how we can reduce the operating cost of rolling mills.

What is the main purpose of a rolling mill? It is to form metal. Depending on the client’s demands and the goal they want to achieve, the thickness will vary. Now there are various categories of rolling mills, and they are differentiated based on the temperature. For instance, if the temperature is above the level of recrystallisation, i.e., hot, then it will be considered hot rolling but if it remains below the recrystallisation temperature, then it shall be regarded as cold rolling. 

One of the biggest concerns of manufacturers worldwide is the operating cost. Luckily, with a few alterations to the operating process, the manufacturers can drastically decrease the cost without altering the end product. 

Here are a few steps with which you can reduce rolling mill costs-

1. Energy Consumption 

The first thing that needs to be done is the reduction of energy consumption. On a daily basis, there is a lot of energy waste during operation, and there is no track of it. Our priority is to reduce the energy cost of the unit. How should we do that?

  • There is a dire need for high-quality machinery in daily operation. The main reason is that advanced machinery and its mechanism will reduce rejects. If there is a reduction of rejects from 1.5% to 2%, this small shift can decrease fuel use up to 9%. 
  • The electricity used during the rolling process can also be decreased significantly if motors are used in conjunction. This process is highly efficient and reduces nearly 1%-2% energy consumption. 
  • A decrease in oxygen levels by even 1.5% in the heating furnace effectively reduces the cost. Energy consumption reduces down to 2.4% once the oxygen reduction is implemented. 

2. Process Optimization

Process optimisation is a key way to control and reduce the operating costs of rolling mills. Multiple components work in sync to utilise state of the art rolling mill. There needs to be constant analysis, evaluation, and improvisation for the best output. The most essential is to reduce downtime and accurate interconnection of the production stages. 

This method effectively increases the productivity of the operation. One can also accurately measure the energy used per unit. In general, optimisation reduces the risk of scale loss and heightens efficiency. This is a practice that can be adopted by steel plant consultants and multiple different metal manufacturers.

3. The Right Equipment 

High-quality rolling mill equipment plays a major role in the operating cost and impacts the overall value in many ways. Good quality equipment reduces maintenance costs as you will omit the need for regular maintenance as these are much more reliable.

It also reduces system downtime significantly and improves operation costs. High-quality equipment also has replacement parts readily available, making replacing much smoother. 

4. Leverage Automation

When it comes to reducing the cost of the rolling mill, leveraging automation can be incredibly useful. Making any production process efficient requires advanced mechanical equipment, process technology, and automation functions. These three together can transform the overall cost of operation.

The more suitable software and electrical equipment used will allow more accurate information to be received by mill operators to automate and unify mill setup. This process improves overall operating practices and reduces costs. 

Find The Most Reliable Partner in Steel Forming

The Steefo Group is your reliable partner in steel forming when it comes to steel forming. They provide the most high-quality products and turnkey solutions from concept to commissioning. Advanced machinery, highly skilled engineers, state-of-the-art manufacturing facilities, and undisputed quality make the Steefo Group an eminent steel rolling mill manufacturing company in India.

How to Select The Most Suitable Rolling Mill Equipment

 

When it comes to metal rolling and deformation, the critical component essential to the operation is the steel rolling machine that determines the level of production and technology. Therefore, it is crucial to select the best rolling mill equipment suitable for all your needs and positively impacts the mill’s functioning.

How to Select Steel Rolling Mill Machines?

Several factors come into play when selecting the perfect rolling mill machine. Some of them are: 

  • The steel grade
  • The production scale 
  • The product variety 
  • The production process and more. 

When it comes to the process design of the rolling mill, we also consider numerous components such as- 

  • The structural type of the rolling mill 
  • Choosing the number of rolling mills 
  • Laying method
  • Technical parameters 

Now that it is time to pick the steel rolling machine, one should always remember that the rolling mill should have a reasonable composition and compact arrangement. It should also have a high equipment utilization and impressive production efficiency. Another important aspect is to guarantee that the product quality is up to the mark, not only for current production but also for new production capabilities. 

Apart from that, a suitable rolling mill should facilitate the scope of automation and mechanization to significantly upgrade the working conditions of the employees and be advanced enough to be easy to operate and maintain. Speaking of maintenance, this includes having an easy availability of spare parts that facilitate long-lasting usage. A green flag to consider is the availability of good economic and technical indicators. 

Rolling products and rolling mills come in an exhaustive assortment. Due to the plethora of products, the characteristics of the products differ significantly during rolling. That is why various products have various requirements for rolling mills. 

For example, what is the number one priority for large-scale blanking machines heavy plate rolling mills and more? Well, apart from the required precision? The most crucial thing is the ample strength that allows the large deformation of rolled products. Similarly, plate steel mills, wire mills, and more require substantial and sufficient rigidity; a degree of strength is needed to operate smoothly. 

Why Rely On The Steefo Group For The Best Rolling Mill Equipment?

So you are looking for suitable rolling mill equipment. Look no further as The Steefo Group can provide you with everything your rolling mill will ever need.  For almost four decades, we have been the ultimate and the most favoured integrated rolling mill manufacturer.  The Government of India also acknowledges us as the Star Export House, and we adhere to our reputation.

The Dramatic Rise in demand for TMT Steel Bars in India

The introduction of Thermo Mechanically Treated (TMT) steel bars began a new era in the Indian construction industry. Round plain steel reigned supreme until the sixties but was then ousted by TOR steel in the seventies and maintained dominance until the nineties came into the picture. In the late nineties, TMT steel and corrosion resistance steel made their grand debut, transforming the face of RCC structure by making them more resilient and long-lasting. 

What Makes TMT Bars Stand Apart?

The term TMT bars has become the industry staple for constructing any structure, starting from bridges, flyovers, dams, hydel power plants, industrial structures, high-rise buildings, rapid transport systems, and more. TMT or Thermo Mechanically Treated bars uses Quenching and Tempering technology during production, obtaining their unique strength from that process. There is no chemical treatment involved in the manufacturing of TMT bars. 

But what gives TMT bar the unique edge that allows them to conquer the construction industry? 

Here are some of the attributes:

  • TMT bars’ carbon content is limited to 0.2% to achieve weldability and suffers no strength loss. 
  • Ordinary electrodes have the ability to weld joints without any extra precaution.
  • Due to their tough exterior and soft interiors, they have incredible ductility.

TMT bars tick all the three crucial boxes, strength, weldability and ductility, making them economical and safe for usage. A bonus is the corrosion resistance that TMT bars obtain since the cooling process avoids the formation of coarse carbide. The soft ferrite pearlite increases seismic loading. TMT bars are usually produced in Fe- 415, Fe – 500,  Fe – 550, Fe 500D, Fe 550D grades with diameter starting from 8,10,12,16,20,25, 28, 32, 36, 40 MM, with a standard length anywhere from 5.5 -13 metres.

TMT Bars and the Indian Market 

India’s iron and steel industry has come to occupy a dominant place in the country’s socio-economic development. India also ranks seventh as the largest crude steel-producing nation in the world. The Indian steel industry has gone through tumultuous business cycles, with several ups and downs. Today the industry is on the cusp of a significant change as it gears toward an expansion of ambitious standards. 

The secondary producers of the Indian steel industry are joining forces with the main producers. The emergence of the secondary producers has initially been modest in the post-liberalized decade in the steel scene. Still, it steadily contributes to the development of the domestic steel and iron industry in aspects of capacity, production, spread,  necessitation and commodity basket. 

Steel production in India received a massive boost with the introduction of the Industrial Policy Resolution of 1956. This is where the public sector saw three SAIL plants being set up in the late 1950s and the fourth one in the early !970s. These plants, along with VISL, TISCO and IISCO(now a part of SAIL), were the sole producers of integrated steel till the eighties (RINL came into production in the early nineties)  

There was a rising demand for the secondary sector for smaller-scale steel producers in the seventies. Specifically for those who had opted for induction furnace routes or the scrap-DRI based electric arc furnace, particularly for meeting local demands. 

Semi-finished billets and ingots manufactured by this part led to the commissioning of considerable re-rolling units to transform semi-finished steel into rods and bars that can be utilised mainly in the construction industry. 

The re-rolling part faced several market challenges, especially in high energy consumption and prices. However, there is a bright prospect of future growth, given the pace of construction and infrastructure activities. Experts estimate that the secondary producers in total crude steel production will increase from the current under -50% mark to at least 53%. 

We are also seeing an increase of foreign steel plants setting up steel plants in India, gearing up to venture into their dream project as the steel industry of India prepares for a new era. An era that will include the dominance of the Indian iron and steel industry. The steady growth of the Indian economy because of the steel industry has also increased infrastructure from township complexes to roads, bridges, and civil construction projects, which guarantees the continuous demand for TMT bars.

5 Best Reasons Why TMT Bar is the Future of the Steel and Construction Industry

The Indian construction industry has gone through a transformative phase since the late 1990s, both in technology and research. The proof of this rapid developmental stride is in the steel industry’s products- most of today’s products did not exist a decade ago. The industry has also made its presence in India’s numerous developmental plans in rural, urban and metropolitan areas. With the introduction of robust technological advancements, the popularity of steel products has also increased in the nation. 

But to be the future of any industry, products must meet the growing consumer demands and address the environmental factors. Historically, the steel industry has always been associated with ecological deterioration and destruction. To improve upon that aspect, the steel and construction industry worldwide has advanced into more environmentally conscious modes of production. The goal is to become more sustainable and reduce the industry’s carbon footprint. 

Here is where products such as the TMT bars come into action. TMT bars have proven to be the solution as the bars have adapted to future demands. Let us find out how they have proven to be a massive asset to the construction industry. 

What are TMT Bars?

Before we delve into the benefits, let’s find out all about TMT bars? ‘Thermo Mechanical Treatment’ bars, better known as TMT bars, are among the most necessary construction materials worldwide. They are high-strength reinforcement bars manufactured using a distinctive technique that endows them with a rigid outer surface and a soft internal core, making them strong yet flexible.

TMT bars are steel bars of a new era, suited for concrete reinforcement. These bars are employed widely in modern-day construction work, emphasising quality, safety, and longevity. 

Before TMT Bars

Before TMT bars came into the industry, Cold Twisted Deformed Bars, also known as CTD bars and M.S or Mild Steel Bars, were used for Reinforced Cement Concrete work. These bars failed to deliver on ductility and corrosion resistance compromising structural integrity in the long run. Hence, TMT bars came into existence to combat the downsides of previous construction materials and have now evolved into the most commonly used material for long-lasting structure construction. 

Why is TMT Bar The Future of the Industry?

When we observe the construction industry’s economy, we can witness the advent of the TMT (Thermo mechanically treated) steel bars. These bars are paving a new epoch of advanced growth and demand graph in the steel market.

Here is the reason why we are seeing such growth: 

1. Recyclability and Waste Management

The steel industry is circular, meaning that the generated waste can be used as an input in further production without losing its core properties. Therefore a waste generated can easily be melted and reconstructed, raising the rates of recovery in comparison to other products. It is also relatively easy to recover steel from other waste materials. At present, recycled steel represents as much as thirty percent of the whole new production process of steel making.

2. Longevity 

A key reason why TMT bars are becoming the face of the future of construction is their longevity. TMT bars production takes place, keeping in mind durability. Before TMT bars, iron rods were used in construction, making them prone to corrosion. For example, during the CTD bar manufacturing process, the method of twisting the rods negatively affects the ductility of the bar. It also breaks the protective blue oxide, making the CTD bars susceptible to corrosion.

On the other hand, TMT bars obtain anti-rust properties during the manufacturing process. Due to the intense cooling, coarse carbide, which is the foremost cause of the corrosion, does not get a chance to build up, creating the most durable bars. 

3. Strength 

Compared to ordinary reinforcement bars, the strength of TMT bars sets them apart and makes them the most suitable choice for any construction. The reason behind their strength and ductility is the extreme cooling it receives. The manufacturing process passes through a water cooling system which causes the outer surface to toughen. The ribbed texture of the TMT bar also allows better adhesion with the concrete, offering it more strength, while the flexibility makes it easier to work with. 

4. Disaster Resistant 

All scenarios are considered during construction, even the possibility of man-made or natural disasters. TMT bars are known to be earthquake and fire-resistant, making them a safer choice than other bars. 

The advantage of using TMT bars is their high thermal stability. Because of this property, they can tolerate severe temperatures varying from 400 to 600 degrees Celsius and maintain more than 80% of their ambient temperature yield strength at 300°.

TMT bars are a staple in earthquake-prone zones due to their ability to withstand high levels of stress and pressure because of their fatigue-resistant properties. The soft inner core and the rigid exterior make the bars very ductile, which permits them to absorb shock causing minimal damage to the structure.

5. Weldability 

Architects and engineers are looking to create more unorthodox and unique designs in this modern era without compromising basic structural integrity. TMT bars have high weldability because of the low carbon content. Also, since there is no pre or post-welding treatment, the process is more efficient for the workers.

The Future of TMT Bars

The growth potential of TMT bars is very promising, mainly because of the speed and scale of the infrastructure and the construction activities. Since India is still a budding market, construction-related works have a tremendous scope, which can pump the demand potential in the steel and TMT industry markets.

Energy Saving Technology of Rolling Mill System

The steel industry often earns itself a reputation for being energy-intensive. But with recent developments, there has been an opportunity to transform and walk toward the path of energy efficiency. 

In rolling mills, during the production process, intermediate steel products obtain their shape and dimension because of an array of shaping and finishing techniques. To get their shape, slabs are heated to an extreme temperature in the reheating furnace and are then rolled into shape with hot or cold rolling or in finishing mills. Some products specifically require hot rolling, such as reinforcement bars, steel plates, etc. Some products like steel for cars and white goods require both hot and cold rolling. 

But the energy needs and costs for both hot and cold rolling can be significantly high. Due to the cold rolling process, the mechanical forces create much more force and increase the energy needed. In the hot rolling process, the execution is faster as it consumes less force, but substantial energy costs are incurred to heat the metal to near eutectic temperatures. Data accumulated from large integrated plants show that the hot strip rolling process is the third-largest energy user apart from iron and steel making. 

Reheating Furnaces

Reheating furnaces is critical in determining end-product cost and quality in any hot rolling operation. The energy use in a reheating furnace is determined by several production factors such as stock, steel type, etc., and operational factors such as scheduling and design features. 

Globally, the total primary energy requirement for hot rolling was reported at 2 – 2.4 GJ/t, and global average energy needs in cold rolling are between 1 – 1.4 GJ/t. (IEA 2007). The way to harvest energy savings could be via upgrading existing furnaces.

Rolling Mills Technology And Measures To Be Energy Efficient  

1. Process Control in Hot Strip Mill

To improve indirect energy savings through reduced oxygen rejects, we require improved hot strip mill process control. The main objective is to control and monitor oxygen levels to optimise the combustion rate in the furnace. It also enhances productivity and reduces downtime. We can see results from a system installed at a mill in Belgium, which reduced rejects from 1.5% to 0.2%and decreased downtime from more than 50% of the time to 6%. It also leads to a reduction in CO2 emissions by 15.1kg of CO2/t-rolled steel.

2. Oxygen Level Control and VSDs on Combustion Fans

To optimise combustion in the furnace, controlling oxygen levels and using Variable Speed Drives (VSDs) on combustion air fans on the reheating furnace helps significantly. There is a substantial drop in combustion efficiency with excessive air as it leads to unnecessary waste gases. The fuel to air ratio, therefore, should be monitored regularly. The usage of VSDs on combustion air fans also helps keep the oxygen levels on the reheating furnace under check. 

This process has the potential to reduce emissions by 16.6kg CO2/t-rolled steel. It also calculates energy savings to be around 10% or 0.33 GJ/t-rolled steel by a conservative estimate.

3. Pressure Control for Furnace

There are multiple apertures that heating furnaces have, such as extraction ports, raw material charging ports, cracks in the furnace ceiling, and sidewalls. There can be unnecessary heat losses if the pressure in the furnace is too high, causing the heat to be forced out of the furnace.

Due to this, if the internal pressure drops, cold air will be sucked into the furnace, spiking up the fuel consumption. The furnace pressure control technology’s objective is to maintain a constant optimum pressure level to minimise energy consumption.  It is primarily applicable in cases of industrial furnaces, including rolling mill reheating furnaces. 

4. Regenerative Burners for Reheating Furnace

A regenerative burner is a heat recovery system that recovers the furnace exhaust gas’s waste heat to heat the furnace’s combustion air. Heat reservoirs and dual heat-recovering generators of the regenerative burner are utilised. One side of a burner combusts fuel during combustion while the other accumulates the exhaust heat into the heat-recovering generator. 

The burners then switch so that the one collecting the heat combusts the fuel while the other gathers exhaust heat. The usage of regenerative burners for reheating furnaces can deliver significant energy savings. According to NEDO, using regenerative burners on a 110 t/h capacity billet reheating furnace (operating at 1050 oC) can reduce the energy consumption by 0.18 to 0.21 GJ/t-steel in comparison to a conventional furnace.  Annual energy savings are reported to be 9.3 to 11.6 GWh. There is a scope of up to 50% NOx reduction in high-temperature combustion.  CO2 emissions will also be reduced according to the reduced fuel consumption. 

5. Walking Beam Furnace

If you are looking for state-of-the-art efficient reheating furnaces, you will have to look towards a walking beam furnace. In a walking beam furnace, the stock is located on the stationary ridges. The revolving beams walk the product through the furnace till it reaches the exit, where the beam returns to the entrance.

Compared to the three-pusher-styled furnace, installing a walking beam furnace and an efficient control system reduced energy and fuel consumption by 25% and 37.5%. It also provides lower operational costs compared to alternative transmission systems.

Bottom Line

Energy efficiency is a goal that many industries, including the steel industry. Investing into methods reduces exorbitant energy consumption and saves you from facing cost overruns due to lack of optimization. This step toward energy efficiency is also a step toward a better and greener future as many methods cut down on CO2 emissions and improve productivity.
