TMT bars support the foundation of any building or structure, a strong foundation is the first and the most important step in the formation of invincible building construction. A strong TMT bar has to go through numerous tumultuous processes to help support the strong foundation of any structure.
The manufacturing process of a TMT bar involves a series of small processes like rolling, water quenching, heat treatment, and cooling at various stages of manufacturing to get rid of any significant impurities that might affect the quality of the bar. The production process of the TMT bar holds extreme importance as it will eventually determine the strength of the bar produced.
The process of manufacturing TMT bars entails several steps, which are as follows:
Turning iron ore to iron
iron is the initial raw material that is first converted into steel billets to obtain a TMT bar which is our end product. The iron is produced out of the iron ores, which are generally impure and need to be cleaned and turned into a pure iron form.
Formation of sponge iron
sponge iron is formed by the reduction of iron ore to metallic iron through reaction with carbon in the form of coal, etc. at approx. 1100 degree Celsius. Sponge iron is also referred to as direct reduced iron, metallizes iron, or hot briquetted iron.
The raw material is placed in the furnace and treated with hot gas while in its liquid form. The molten state of iron is pre-processed and converted into steel. iron ore and other iron-bearing materials, coke, and limestone are changed into the furnace from the top & work their way down, becoming hotter as they sink into the body of the furnace which is called the stack.
Continuous casting machine
The liquid form of steel is then poured into a casting machine to get the billets. At this point, the iron ore gets purified, and all the impurities get accumulated in the form of slag.
Formation of billets
steel billets are the first raw materials generally used in the formation or manufacturing of a TMT bar produced by casting iron metal into steel mechanically. Billets are solid lengths of metal with square or circular cross sections. These billets after undergoing a continuous rolling process are converted into solid TMT bars.
The best TMT bars are produced in highly automated, integrated TMT rolling machines. Modern rebar rolling mills use the most recent technological advancements to thermo-mechanically treat steel bars, giving them a hard outer core and a soft inner core, giving them high reinforcing the strength and giving them better ductility. In fully automated and integrated TMT bar rolling mills, the entire integrated process of producing TMT, from melting iron ore to rolling TMT to quenching, is carried out.
The last stage of the TMT bar's manufacturing process is the thermo mechanical treatment. There are three further steps that follow the formation of the final product.
we can in no case compromise the quality of the TMT bars as they are the foundation of the entire building structure. Leniency with the quality check might invite a series of construction disasters.
Ready to Dispatch
the final stage after the preparation of TMT lots and clearing the quality check process, the product is ready to dispatch to the retailers.
Bansal TMT bars are the best in quality, earthquake-proof, flexible, and rust-resistant reinforcement TMT bars. We are committed to building a strong foundation for the future by doing our best in whatever projects we undertake.
