The rolling process requires considerable amounts of energy. High horsepower motors turn the rolls, and highpressure hydraulic systems control the rolls and other mill equipment. Rolling fluids on steel mills include water, wateroil emulsions, waterglycol solutions and petroleumbased products.

If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.

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.
