Vela TMT high quality Thermo Mechanically Treated (TMT) bars are manufactured using the most contemporary technology available worldwide and supervised by metallurgists and engineers. Reheating furnace, pre-finishing & finishing mill, continuous shear to cut bars, roughing mill, intermediate mill, besides the most modern TMT facilities.
Our TMT steel bars are made using the 'Quenching & tempering' (Q &T) technology.
This technology is introduced by RA TMT TECHNOLOGY, A contemporary technology, it allows the production of bars to be on par with international standards. Hot
rolled from steel billets and subjected to PLC-controlled online thermo-mechanical treatment, the bars are made to pass through heat treatment over three successive stages.
1) Quenching
In the first stage of 'Quenching', intense water quenching is executed on the periphery while the core stays unchanged, leading to a martensitic surface and austenitic core. The quenching is done using a special water spray system.
2) Tempering
Subsequently, the bar leaves the quenching box to undergo a process of'Self Tempering In this stage, heat from the austenitic core flows to the Surface,
causing the tempering of die outer martensitic layer into a structure referred to as ‘Tempered Martensite'.The core remains austenitic.
3) Cooling
In the final stage of 'Atmospheric Cooling' that takes place on the Cooling Bed, the austenitic core is transformed into ductile ferrite-peariite structure. The end result is a line combination of a strong outer rim (tempered martensite) and a ductile core (ferrite-pearlite), thereby imparting strength as well as ductility.
After the quenching process, the bars are cut to desired sizes with the Shearing machines and transferred to the Cooling Bed wherein they are cooled to get the defined structure. Unlike conventional bars that are subjected to cold twisting.TMT bars have high strength, greater yield & elongation, uniform micro structure, toughness, ductility and weldability. They also bond better with cement concrete mix. Hence they are equipped with the requisite properties to provide strength to Structures for enduring natural hazards.
