Obtener precioThere are two types of processes. One is Hot rolled and another is Cold Rolled. If the strip is rolled after heating the strip above the recrystallization temperature then it is termed as Hot rolled and if that done in room temperature then it is termed as the Cold rolled. Rolling is a process that is widely used and has very high production.

Obtener precioThe hot metal is converted into steel through a steelmaking process called the LD process. Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill. Long Products:

Obtener precio5, 2020. Rolling in metalworking is a metal forming process that helps to reduce the thickness of metal and make the thickness uniform. The metal stock is passed through one or more pairs rolls to reduce the material. Rolling is classified according to the temperature of the metal rolled, it is a hot rolling if the temperature of the metal
