In the hot rolling mill, a cold slab is reheated in reheating furnace and then rolled into thin coils through hot rolling process. Traditional research on hot rolling mill generally takes the two processes as two separate singleobjective scheduling problems, though they are closely connected and their optimization objectives are conflicting with each other.

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.

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the ...

In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types. Cold rolling mills may be further divided into continuous or batch processing.
