  • Horizontal loopers

Vertical Loopers 

As the name suggests, vertical loopers move hot steel bars around the steel rolling mill vertically, generally in an upwards position. The vertical looper is employed to raise the hot steel bars to an elevated position from a lower one. These bars can then cool and straighten to receive their final shaping. 

These types of loopers are perfect for steel mills where hot steel bars need vertical motion, like mills with rolling stands in operation. 

Horizontal Loopers

For horizontal loopers, they transport the hot steel bar from one side to the other of the steel mill horizontally. The horizontal looper is employed, especially when hot steel bars must move through numerous processing stations to get to their temporary storage location.

This kind of looper and its horizontal movement is beneficial when steel bars need to go through continuous rolling mills. 

How To Choose The Right Looper? 

The looper type relies on the specific needs of the steel rolling process and the mill’s overall layout. Both vertical and horizontal loopers play an essential role in managing the movement and processing of hot steel bars in a steel rolling mill, and both have their unique advantages.

What Are DC Motors?: A Beginner’s Guide

 

We have heard the term “DC  motors” pop up across several industries but have you ever wondered what it means? DC motors are an important component utilized across numerous industries, from rolling mills to elevators. Today let us take a look at DC motors, what it is, their applications, their overall importance and more.

What is a DC Motor?

DC motors or Direct Current Motors are machines that specialize in transforming electrical energy from a battery into mechanical energy. When the electrical energy or current passes through the power source and directly into the motor, the energy is transformed and recast into mechanical rotation. Mechanical rotation happens because this process allows wheels, blades and propellers to spin along with other elements.

How Does A  DC Motor Operate?

DC motors operate by employing their power source to create electrical energy or current inside the motor’s brush. This process, along with stator magnets, produces magnetic fields. The magnetic field created by the electrically charged brushes is used to generate movement in the rotor. The electrical input and the type of motor also determine the speed of the motor and the amount of torque.

What Are The Parts of a DC Motor?

DC motors or Direct Current Motors have numerous parts, although they might vary based on the type of DC motor. However, the parts mentioned are found in your average DC motor.

  • Axel: Responsible for holding the commutator and the armature.
  • Armature: A collection of electromagnets responsible for electrical current and its movement.
  • Commutator: Permits the discharge of electricity to the armature
  • Stator Magnets: Responsible for creating a rotating magnetic field for the armature.
  • Brushes: Operates along with the commutator to provide proper rotation.

What Are The Different Types Of DC Motors?

Direct Current motors, or DC motors, can be classified into four different categories. These categorizations allow you to comprehend how these DC motors operate and their various uses. 

1. Permanent Magnet DC Motor

In Permanent Magnet DC Motors, permanent magnets are employed to create the field flux. Field winding on the stator frame is not present in this type of DC motor. It instead operates on permanent magnets to create a magnetic field allowing the rotor field to interact and generates torque. These DC motors are known for their high initial starting torque and can regulate speed thoroughly.  

2. Series DC Motors

In Series DC motors, the full armature current courses via the field winding. Series DC motors also comprise significantly larger conductors in their windings. This allows the motor to have a minimal resistance, which permits them to obtain and accept a larger amount of power supply. The primary drawback of these DC motors is that heavy loads can majorly impact speed.

3. Shunt DC Motors 

Shunt DC motors are where armature and shunt field windings are parallel to each other but not to the series field winding. Since the shunt field can be operated without the armature windings, it allows for easier control on reversing. Shunt DC motors have incredible speed control and regulation despite the load on the motor. This ability makes shunt DC motors ideal for operations that require accurate speed control. 

4. Compound DC Motors

Compound DC motors contain both series winding and shunt field winding. These DC motors usually provide great starting torque but may have control issues during variable-speed drive usage. The motors in the compound DC motors have the ability to be connected in two methods: differentially and cumulatively.

The cumulative connection type joins the series field to assist the shunt field, equipping it with a higher starting torque but lower speed control. On the other hand, the differential connection type has great speed control and usually functions at a steady speed. 

What Are The Applications Of Different DC Motors?

Permanent Magnet DC Motor is employed in several household appliances and day-to-day appliances such as blowers, air conditioners, toys, electric toothbrushes, power tools, heaters, food mixers, and ever objects like windshield wipers and more.

Series DC motors are typically used where high starting torque and speed variations are necessary. This type of DC motor is used in sewing machines, portable electrical appliances, vacuum cleaners, winches, air compressors and more. They can also be seen in traction systems, engine starters, and cranes and are utilized to cowl and control airplane wings.

Shunt DC motors are utilized for items requiring constant speed. The shunt dc motors applications are in centrifugal pumps, weaving machines fans, blowers, conveyor belts, lifts, mixers, spinning machines, etc.

Compound wound motors are operated where you require higher starting torque and constant speed. These DC motors applications include printing presses, shears, cutting machines, conveyors, elevators, steel rolling mills, heavy planners, industrial mixers, etc.

A Comprehensive Guide to Hot Rolling Mill Process

 

The main objective of the entire steel rolling process is to create complete or semi-complete parts by deforming the massive plates and ingots to decrease the cross section in them. In metalworking processes, hot rolling mill is considered to be a commonly-used technique. In this technique, metal is heated beyond the recrystallization temperature, and the plasticity is distorted during the rolling procedure. This process ensures that the volume and features of the metal are maintained while creating various shapes and dimensions.

After being heated, the metal goes through rolling devices to retain its volume and uniformity while flattening and reducing the overall cross-sectional area.  The construction sector often employs the hot rolling process and the product it creates. The hot-rolled steel from this process is great as raw material and the final product.

How Does The Hot Rolling Process Work For Steel And Stainless Profiles?

Steel billets and blooms are heated at an extreme temperature to initiate the hot rolling procedure. The temperature surpasses a minimum of 1100 degrees and is changed depending on the requirements of the process. The metal is passed via the rolling mechanism to ensure there is damage on the edges and structure of the metal grain. This process ensures that new and sturdy designs and boundaries are produced with uniform grain structures and volume,

At a high temperature, the slabs or blooms pass through the casting process and are then fed into the rolling mills. The metal’s strength, toughness, ductility, formability, resistance to vibration and shock, and weldability are all increased by rolling operations.

During the treatment process, extreme force and pressure are used for metal cleaning and eliminating the mill scales.  Doing so ensures that no surface defects on the final finished items. When the metal cools down, the cooling rate of the steel is to be checked to correct the crystallization and, in general, microstructure depending on the various uses.                                                                       

Why Is Hot Rolling Preferred?

Hot rolling is the preferred method amongst steel rolling mills due to the certain characteristic that it instills in the steel. Steel that goes through the hot-rolling process tends to be

  • Stronger 
  • Tougher
  • More Ductile 
  • Resistant to Shock and extreme vibrations
  • Weldable 
  • Formable 

What Are The Advantages Of Hot Rolling 

When the hot-rolling process is selected for steel rolling , numerous advantages are attached to it that benefits the end product being created. Here are some of the various advantages:

Enhanced Mechanical Properties 

When steel goes through a hot rolling mill, several characteristics and properties of the steel are altered due to heat and pressure. Certain mechanical properties encounter the most change but improve the quality of steel. For example, properties such as elasticity, elongation percentage, shock resistance and overall toughness improve drastically. 

Altered Grain Structure

In the hot rolling mill, the metal’s grain structure changes. The grain structure that plays a vital role gets refined. The usual coarse grain gets transformed into finer grains which alters the properties of the metal. 

Change In Porosity

The hot rolling mill and its process ensure that the porosity of the metal is removed and eliminated. This alternation due to hot rolling creates a stronger, tougher, uniform metal in the structure.

Distribution Of Impurities

Metals and steels have numerous impurities that can affect the final result and how the product is formed. In hot rolling mills, impurities,  such as slag, are distributed throughout in an even manner. If they remained concentrated, those areas would have become weaker and would be prone to breakage. 

Requirement Of Low Pressure:

In hot rolling mills, the metal deformation process is easier due to the extremely high temperature of rolling. This temperature reduces the requirement for high pressure, making the process easier.

Roller Conveyor: An Essential In Rolling Mill Operation

 

Roller conveyors or roller tables are essential to rolling mill plants and their regular operation. Rolling mills use roller conveyors to carefully move material from point A to point B without human intervention. The entire function of roller tables is to ensure efficient and speedy movements of various materials, which is why they are commonly used in rolling mills.

For a roller conveyor to operate smoothly, there needs to be at least one rigid or almost flat object to touch the rollers and retain steady equilibrium. Some of the most primary materials that roller tables carry are steel billets, slabs, bars, ingots, plates and more.

Several types of roller conveyors and roller tables are available in the market, but all of them fall under either one of these classifications.

  • Unpowered or idle roller conveyor
  • Powered or live roller conveyor

Unpowered Roller Conveyors

Unpowered roller conveyors are rollers that are operated without the assistance of an external power source. The roller table works by rolling over multiple rollers with the help of manual push or a form of push from a chain constantly in motion. These idle or unpowered roller conveyors usually function on a horizontal and flat surface or at a gentle incline to assist the roller tables in functioning correctly. An incline rate of 1.5 to 3 percent allows gravity to do much of the work.

Powered roller conveyors

Powered roller conveyors or live roller tables operate when designated, or the entire group of rollers operate with the help of one or more motors depending on the stage of production. The powered rollers are set into motion and move s the load with friction. Powered rollers conveyors also benefit from its inclined installation. The average incline on these roller tables is usually 10 degrees upwards or approximately 17 degrees downwards.

Why Are Roller Conveyor systems Essential To The Rolling Mill Industry?

Roller conveyors are essential in the rolling mill industry due to their utility in every aspect of production.

1. Decreases Manual Wastage 

Roller conveyor systems are essential to the entire production unit and eradicate a lot of manual labour. Automating these tasks expedites the whole production process and decreases the probability of human error, wastage and potential injury.

2. Enhances Flexibility

Since roller tables and roller conveyors are necessary for every step of production, modular roller tables enhance the rate of flexibility. This ensures that these roller conveyors are used in numerous rolling mill applications.

3. Improved Quality And Standard

Roller Conveyors facilitate automation and speedy production and enhance the product’s quality at every step of the process. Due to the roller table system, it is easier to spot any form of deformity or error in the product, allowing companies to rectify it immediately.

4. Enhanced Efficiency 

Roller tables and conveyors can operate 24 hours a day, and are efficient to run compared to other types of machinery. They also increase efficiency and productivity rates, especially during busier times of the year. The parts of these machines are also easy to find and replace in case of damage, making them reliable during the production process.
