production of coils in a hot rolling mill. They are also used to heat steel semifinished products (sheet bars, slabs, and ingots) to a temperature of about 1200 C. This temperature is suitable for the plastic deformation of steel. Hot rolling is a process in which the plastic deformation of said steel semifinished products occurs.
