Roller Conveyor: An Essential In Rolling Mill Operation

Roller Conveyor

 

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.

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:

Reheating Furnaces In Steel Rolling Mills

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. 

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?

TMT 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?

Rolling Mills

 

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

Our products and manufacturing process goes through constant up-gradation and improvement to guarantee that our clients only receive the best of the best.

Now, let us give you a glimpse at our vast product line.

Reheating Furnaces

Reheating Furnaces are essential for hot rolling mills. They help in converting the Billets into rolling temperatures and making them suitable for deformation and further use. The Steefo Group’s reheating furnaces stand apart from the rest because it ensures several benefits that are necessary for improved performance, such as

  • Consistent Thermal Level and Thermal Homogeneity
  • Mark Elimination
  • Combustion Automation
  • High-Quality Refractory Material Installation

Rolling Mill Gearbox

As the number one rolling mill manufacturers in India, we also create rolling mill gearboxes. A gearbox is a housing that contains numerous open gear sets. The housing comprises shafts and bearings and contains lubricants, and protects the component from other conditions. The job of the gearbox is to increase or decrease the speed and torque of the drive unit depending on the requirement. Our gearboxes are available in several load capacities and have multiple speed ratios. The Steefo Group ensures that our rolling mill gearboxes have the best-

  • Dimensional Accuracy
  • Reliability
  • Optimum Performance

Mill Stands

Mill Stands are an essential part of rolling mills. They can do quick roll change and complete automation to create numerous products, namely, wire rods, universals, channels, beams and more. The Mill Stand produced by the Steefo Group has several purposes, such as the hot rolling of wire rods, TMT bars, strip mill and much more. To work with the demand of our clients, we ensure that our mill stands can be upgraded and customized. Fibre Bearing and Anti Friction Roller bearing upgrades in our conventional stands are some.

Shears

The Steefo Group has the expertise in creating some of the best shears among all rolling mill manufacturers. The Shearing machine is an integral part of the entire hot rolling process. These are installed to cut the tail end and the length. This step is taken to fit the cooling bed and the commercial length of the TMT bars. Our shears have the Steefo guarantee of being of superior build and performance-driven.

Pinch Rollers

A Pinch Roller created by the Steefo Group is essential when working with hot rolling and strip steel mills. Pinch Rollers operate horizontal cantilever structures that require an air cylinder and double roll device, which allows the up and down synchronous roll clamp. A pinch roller aids in removing coil rejection because of poor surface quality. In general, pinch rollers are designed to provide superior performance and can meet the expectation and needs of the hot steel strip coiling application.

Loopers

If searching for the best loopers, you should rely on the ones produced by the best rolling mill manufacturers in India. Our Loopers are required at the finishing mill area for a tension-free rolling process and to ensure accurate section tolerance is achieved. To improve production capacity by reducing miss rolls, installing loopers is critical. Looper also can be installed in the inter-stand position to decrease the tension variation by a simple angle adjustment, improving bar threading and product quality.

Quenching System

The Quenching System supplied by the Steefo Group is trusted by rolling mills in India and worldwide. A quenching system, also known as the TMT box, is installed after the final finishing stands on the mill train to provide the rebars with the thermal treatment necessary to create the product. The Quenching system provided by us also cleanses the surface via scrubbing. These are some of the characteristics our superior quality quenching system offers:

  • Consistent ring formation
  • Uniform tensile strength along the length of the bar
  • Motorized valves
  • Corrosion-free
  • Time-efficient
  • High-quality design
  • Powerful construction
  • Closed frame to adapt the forces in the sizing press
  • It can be operated under extreme conditions

Automatic Cooling Beds

Our Automatic Cooling Beds are necessary to cool down TMT bars by using uniform air cooling and are also used to transport it in a phased manner to the discharged side. These beds also provide alignment when they are transferred onto the roller table to the finishing section.

Packing Beds – Tying & Bundling

The Steefo Group creates superior quality and advanced packing beds for steel rolling manufacturing. Packing beds are necessary for tying and bundling rebars. These packing beds are critical, enhance productivity, and improve plant function.

Roller Table – Conveyor

We manufacture some of the most efficient range of Roller conveyors or roller tables necessary for rolling mills. These roller tables transfer a billet to the charge furnace, then transfer it from the furnace to the roughing mill and cooling bed. It is then used to shift the product to the shearing machine, which is cut depending on the desired length.
