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.

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.

5 Benefits of Rolling Mills for Small Manufacturers

 

Rolling mills come with various constructions and are an integral part of any small industry in India. No matter the size of the rolling mill machinery, their performance remains the same in handling heavy metals. You might wonder what a rolling mill is and how it is profitable for small manufacturers? Read on to learn more so that you can make an informed decision.

What Are Rolling Mills?

Rolling mills are a type of metal forming machinery. They help process various metals through one or more rolls to reduce or create uniform thickness or imprint a design.

All rolling mills have at least one pair of heavy rollers. Depending upon your use and requirement, you can opt for mills with more than one pair of rollers that are also heavier to mould high-density metals. The range of sizes the rolling mills offer makes them profitable for small manufacturers.

How Does a Rolling Mill Work for Manufacturing Units?

Rolling mills can help alter the physical properties of a metal sheet. The purpose of a rolling mill is to provide a uniform thickness and consistency. These rollers are constructed with a strength that can easily squeeze and compress hardened pieces of metal as they are passed through a pair of adjoining rollers. 

No matter the initial shape of the metal, once they are squeezed out of the rollers, they acquire a uniform flattened shape ready to be used in various spheres of small-scale and large-scale manufacturing facilities.

Advantages of Installing Rolling Mill Machinery 

Rolling mills come with many advantages for both large-scale and small-scale manufacturers, catering separately to varied needs.

1. Ideal for Processing Metal

For ages, rolling mills have served as the perfect machinery for processing metals of varying densities. Not only do they save time in beating and flattening the metals into sheets, but they are convenient to small-scale manufacturers who place the utmost importance on efficiency and perfection in their work.

2. Good Consistency

Small manufacturers need the highest accuracy in their products because they produce metal sheets of comparatively smaller sizes and less in numbers than large-scale manufacturers. It is only through rolling mills that such constant uniformity is maintained throughout the long material length.

3. Easy to Use

Being able to use good quality rolling mills is no rocket science if you learn the basics of the machine. You can also get a test run to learn how to operate the mills efficiently.

4. High Productivity Rate 

For a manufacturing unit, large-scale or smaller production facility, a high productivity rate in minimal time is the goal of all. With a one-time investment in rolling mills, you can boost the production rate. These machines can help you save time, ensure accuracy and time efficiency, and are a wise investment overall.

5. Lower Operating Cost

Rolling Mills primarily come in two categories: Hand-powered and Electric rolling mills. Hand-powered rolling mills are cost-effective for a firm and preferable for small-scale manufacturers. Electric rolling mills are known to save power, ultimately reducing costs in the long run.

What is a Rolling Mill? Why is the Steefo Group the Best Rolling Mill in India?
Hot rolling is a metalworking process whereby metal is heated above its recrystallization temperature for plastically deforming it in the working or rolling operation. This process is used for developing shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal. Hot metal is passed between two rolls to flatten it, lengthen it, reduce the cross-sectional area, and for obtaining a uniform & consistent thickness. Hot-rolled steel is the most common product of the hot rolling process, which is widely used in the metal industry. It is extensively used as an end product or as raw material for subsequent operations. A rolling mill, by its name, suggests a mill or a set up whereby heated billets are rolled between rollers, which result in the production of sheets and bars, into required forms and sections. While the process of hot rolling has matured since the era of industrialism, constant advancement and automation have increased the demand for higher quality.
