Everything You Need To Know About Shears

What Are Shears? 

Shears are a crucial part of every steel rolling mill. A shearing machine is used to slice plates, bars, thin metal sheets and beams. These machines cut steel and several other mayoral of various dimensions. We at The Steefo Group are one of India’s biggest manufacturers of industrial-grade shears. Our design focuses on precision and superior quality, which is operated with the assistance of the most advanced technology in the market. With our wide range of shears as well as customisation options, you will be able to see a major improvement in your business. 

Type Of Shears 

Flying Shears 

A Flying Shear is a standard industrial instrument known for cutting a constant product at a determined length at line speed. Flying shears do not interrupt the primary production, ensuring maximized productivity. The flying dividing shear created is intended to cut the TMT bar according to the length of the cooling bed. These flying dividing shears have a finishing speed of 20mps.

End Cutting Crop and Cobble Shear

End Cutting Crop and Cobble Shear are utilized to trim the front and tail end. They also come into action for segment-cutting hot rolling eventualities. These shears are managed by a PLC system and provide tight tolerance for cropped or shortened length. End cutting crop and cobble shears are also started/stop type shears operated with the help of a direct dc motor or a mounted Flywheel Pneumatic Clutch/Brake.

Cold Shears

Cold shears are crucial to the rolling mill process due to their placement. These shears are placed right at the end of the cooling bed of the rolling mill. Their incredible high strength capacity performs well when it comes to cutting metal in a wide variety of shapes and sizes. They are also highly customisable and can be designed for your specific requirement. The three most common type of cold shear that are produced are:

  • Pneumatic Clutch Brake Type Cold Shear
  • Hydraulic Cold Shear
  • Electro-Mechanical Cold Shear

Rotary Shear

Rotary shears are a preferred choice by numerous rolling mill manufacturers due to their cost effectiveness and performance. These shears are employed to cut the front and end portions, and discard pre-quenched bars during any contingency. These shears rotate continuously and are usually placed on shortening hot-rolled bars at a low speed.

Hot Saw and Cold Saw

Cropping structural sections are a necessary part of the rolling mill procedure—hot saws cut front and end sections in the required length. 

There are two types of hot saws available – 

  • Horizontal shift type
  • Static type

Cold saw, also provides precise and accurate cutting, where both open and closed types are available. They are utilised with a start and stop the drive, managing structural units and high alloy steels.

Hydraulic Shear 

A hydraulic shear  machine is a type of machine that operates with the assistance of a suitable and reasonable blade gap to utilse cutting force to rolling mill metal plates of various dimensions and thicknesses, employing an upper blade that is in motion and a lower blade fixed onto the surface so that the plates can be split, trimmed and separated according to the necessary size

Reheating Furnaces In Steel Rolling Mills

 

Reheating Furnaces serve the purpose of heating steel blooms, billets or slabs in steel rolling mills. Reheating furnaces takes this steel stock up to approximately 1200 degree Celsius. The steel begins to deform at this temperature, and the steel rolling process can begin. In a reheating furnace, the heat provided to the steel stock is constant. The stock is charged at the entrance, heated up to the assigned temperature in the furnace and discharged at the reheating furnace exit. During the process, the heat gets transferred to the stock in the furnace with the help of radiation and convection. This takes place due to the placement of the burner gasses and furnace walls. 

How Does The Heat Transfer Mechanism Operate In A Reheat Furnace? 

A steel stock charging temperature can vary drastically, ranging from ambient to the high temperature of 1200-degree celsius. Depending on the dimensions of the steel stock, speed of rolling, and overall steel composition, the exit temperature of a steel stock might differ. The factor of steel quality also plays a huge role when it comes to temperature as it puts limitations on the surface and gradient temperature. It is to be noted that both gaseous and liquid fuels are used in these reheating furnaces.

What Are The Main Characteristics Of A Reheating Furnace?

A Reheating furnace’ size depends on its ability to produce hot steel from the cold steel stock and is calculated in tons per hour. The increased heat content determines a reheating furnace and its energy efficiency. When the steel stock is heated from 10 degrees celsius to approximately 1200-degree celsius and is then divided by fuel energy used, efficiency can then be calculated accurately. The energy efficiency of a furnace also relies upon the design aspects of various reheating furnaces. 

Design Features That Plays A Role In The Energy Efficiency Of A Reheating Furnace

  • Different styles of burners
  • Dimensions of a Reheating Furnace. 
  • The total number of furnace zones 
  • Different kinds of roof and wall insulation
  • Design of skid 
  • Combustion air and preheating fuel in recuperators

An energy-efficient reheating furnace is developed in a particular method to allow the steel stock to heat up at a uniform temperature without consuming too much labour and fuel. 

Here are Some of The Important Parameters That A reheating furnace must include:

  • The amount of heat that must be imparted to the charge
  • Creation of necessary heat inside the reheating furnace required to heat the stock and curb steel losses
  • The transfer of heat created onto the surface of the stock that needs to be heated
  • Temperature equalisation within the stock 
  • A decrease in heat losses from the reheating furnace to a minimum 

Several operational approaches also play a crucial role in the energy efficiency of a reheating furnace. The ideal case of a reheating furnace is when the furnace is operated at the rated capacity with one kind of steel stock, which has the same dimension and composition. But often, this practice is not followed, which hampers the efficiency of the reheating furnace. 

Factors that Affect Efficiency of A Reheating Furnace

  • Differences in the dimension and composition of steel stock 
  • Delays in rolling can delay or halt the movement of steel stock in the furnace 
  • The composition of the fuel and its availability may differ
  • The conditions of the burners and the internal  state of the reheating furnace might deteriorate 

How are Reheating Furnaces Classified?

Several types of reheating furnaces are available in an average steel rolling mill, but how are they classified into different categories? Reheating furnaces are usually placed in four categories based on:

  • Heating Method 
  • Charging the reheating furnace method 
  • Steel stock movement inside the reheating furnace
  • Recovery of the heat method

If the reheating furnace is classified based on the heating method, there will be two types of heating.

  • Electrical Heating 
  • Combustion Heating 

Combustion heating reheating furnaces are able to use solid, gaseous and liquid fuels.

When the classification is based upon the steel stock’s movement in the furnace, a continuous furnace can be categorized further.

  • Pusher Furnace 
  • Walking Beam Furnace 
  • Roller Hearth Furnace 
  • Walking Hearth Furnace 
  • Rotary Hearth Furnace 

When the classification depends on heat recovery, there are only two types of reheating furnaces.

  • Regenerative Type 
  • Recuperative Type

The regenerative type of reheating furnace operates on regenerative burners. On the other hand, the recuperative variety of reheating furnaces functions with recuperators. 

Why Choose Reheating Furnaces From The Best Rolling Mill Manufacturers

When you select reheating furnaces from The Steefo group, you are guaranteed superior quality. Get your hands on the most innovative and futuristic products that will help you change the face of your business.  

Our projects and products also experience strict testing and quality checks to deliver best-in-class products. Our emphasis on technology and innovation also delivers up-to-date products for your rolling mill.

Why Are TMT Steel Bars Highly Flexible Compared To Other Steel Bars?

 

Regarding steel bars, flexibility is one of the most critical components that steel rolling mills focus on. With high levels of flexibility, the steel bars can bend effortlessly without breaking. This allows the construction to withstand extra load impact during events such as natural calamities without compromising the structure.

Amongst all the steel bars that are currently in production, TMT bars are one of the flexible steel bars with the best tensile strength. The added benefit of TMT bars being fire and corrosion-resistant makes these bars a preferred choice over any other steel bar. These types of TMT bars are prevalent in countries that experience frequent calamities such as earthquakes, heavy floods and. Some of these countries include Japan, China, Indonesia and more. 

What Is The Significance Of TMT Bars 

Thermo Mechanically Treated(TMT) Bars are commonly known as Reinforcing bars or Rebar. These high-strength reinforcement bars have a tough exterior and soft interior core. Since the creation of TMT bars, they have become highly favoured in construction projects. It has been proven that they are a highly viable option for strengthening concrete structures. It is primarily because of their ability to withstand compressive forces. 

The creation of TMT bars is a process where steel bars go through constant heating and cooling to achieve high yield strength. TMT bars have become a staple in all construction projects. Mostly due to their robust build, appearance and strength with which they provide reinforcements to every concrete structure. 

TMT bars also positively impacted the construction industry due to their resistance to seismic forces. During calamities like earthquakes, due to their inherent flexibility, they minimise the damage done by seismic activities and prevent property damage and loss of life. TMT bars have also achieved thermal resistance, making them the safest choice. The other properties of TMT steel bars, such as high yield strength, tensile strength, and ductility, are just some of the reasons why they stand apart from regular steel bars. 

When the question arises of why TMT bars are significant, it is simply because they transformed the construction industry with their properties. They also facilitated the creation of much more complex yet safer construction projects. 

How are TMT Bars Flexible?

TMT bars have to go through thermal processing in a steel plant. These steps include rolling through heat treatment and water quenching in the steel rolling mills.

When the quenching takes place, the hot rolled bar is cooled in a quenching box within a controlled environment. The water only cools the bar’s surface to ensure that the hot rolled bars’ core retains heat. Then the process of self-tempering begins by adding heat to the surface. The outer layer then hardens and transforms into martensite, resistant to stress and pressure, while the inner core remains soft and austenitic. This process improves tensile strength and ductility and allows elongation to withstand high stress in structures such as flyovers, dams and more.

When the bar passes the final stage, it goes through cooling beds, where the inner layer of the bar converts into a ferrite-pearlite-crystal structure. This microstructure arrangement in the TMT bar ensures that all the properties are incorporated. 

Assessing The Flexibility of TMT Bars

Commonly known as the Bending and re-bending Test, this test determines the flexibility of steel bars. In this test, TMT bars are bent to 135 degrees and immersed in boiling water for approximately 30 minutes. After the time elapsed, the bar re-bent to around 158 degrees. The test ensures that the TMT bars can bend to such degrees without any surface cracks along the bends.

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.

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.
