In the cold rolling of flat steel strips, electric energy consumption is one of the highest expenses. The tandem cold rolling mill (TCM) studied in this paper, composed of four stands, has a total installed electrical power of MW. Such highpower requirements rest in the fact that steel presents a high resistance to plastic deformation.

Steel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.

Rolling schematic view Rolling visualization. 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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
