Hot rolling is generally divided into the following stages: (i) Reheating: the first step, since most steel mills cool the steel to room temperaturd after casting. However, there are more contemporary processing routes that do not involve cooling of the cast strand to room temperature, direct rolling, or hot or warm charging.

WhatsAppعرض المزيدHot 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 semifinished casting products, such as slabs, blooms, and billets.
