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 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.
