The hot steel in rolling mills requires highperformance machinery for handling and transport. In order to remain malleable, these slabs and billets must often be moved at extremely high temperatures, with exceptional reliability. Electric overhead traveling cranes, or EOT cranes, are critical to this process. Their key roles include:

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.

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 ...
