loopers

 

The steel production procedure is a part of a complicated, intricate and highly-specialised industry that demands a plethora of premium quality equipment to manufacture the best steel products.  One key piece of equipment that must be present in the production process to ensure seamless operation is loopers. Let’s take a closer look at loopers and how they impact the steel rolling industry. 

What are Loopers?

Loopers have a simple purpose in the manufacturing process. This equipment manages the material in steel rolling mills by regulating the movement and processing of hot steel bars. These loopers comprise a set sequence of rollers that assist in moving hot steel bars across the steel rolling mill. The purpose of these loopers is to provide a steady and stable condition for the processing of steel bars. This decreases the risk of product defects and improves the quality of the final steel product.

What is the Role Of  Loopers in Steel Rolling Mills?

Loopers are vital in the steel rolling process as they temporarily provide efficient and suitable housing for hot steel bars. During this period, the hot steel bars cool and straighten before starting the rolling process to receive their ultimate shape. Loopers are also responsible for controlling and regulating the tension variation in the steel bars. Doing so reduces the risk of defects and imperfections and enhances the overall quality of the steel bars. 

The looper also enhances the general efficiency and security of the steel rolling mill. Due to the looper, the chances of injury are reduced as it decreases the requirement for manual intervention or handling.

They are also responsible for enhancing the efficiency of the steel rolling mills. It is because hot steel bars travel swiftly during the process, decreasing the time consumed during processing and improving quality. 

What Are The Different Types Of Loopers?

When it comes to loopers, there are two primary types that are operated in steel rolling mills:

  • Vertical loopers
  • 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.

DC Motors

 

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.direction

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. 

Where To Find The Highest-Quality DC Motors?

Are you looking for best-in-class DC motors? Look no further than The Steefo Group. You get assurance on quality when you select DC motors from The Steefo group. You also get your hands on the most ingenious and futuristic products that will help you convert the face of your business.

Hot Rolling Mill

 

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.

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.

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

 

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.
