Project Report on TMT ROLLING MILL (Cap: 12,000 Tons/Month

TMT ROLLING MILL (Cap: 12,000 Tons/Month) After the bars pass, the outer surface of the bars solidifies while the core remains hot. This creates a temperature gradient in the bars. After the intensive cooling, the bar is exposed to air and the core re-heats the quenched surface layer by conduction, therefore tempering the external marten

Rolling (metalworking) Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
