Rolling Mill with Thermex Technology - Shyam Steel

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.
