The hot rolled bar from the finished mill stand enters into the 'Thermex System' and is rapidly cooled by a special water spray system. This rapid cooling hardens the surface of the TMT Re-bars to a depth optimized for each section, forming a martensitic rim while the core remains hot and & Austenitic. This rapid cooling is called quenching.
This creates a temperature gradient in the bars. When the bars come out of the cooling system, the heat flows from the core to the outer surface. It causes further tempering of steel bars thereby helps them in attaining higher yield strength of steel. TMT steel bar is a newer variety of steel for construction purpose.
