This paper presents a heuristic algorithm to schedule a hot rolling mill in the aluminum industry. One problematic issue is the tight coupling between the homogenizing furnaces and the mill, which needs to be integrated into the heuristic design. The latter also takes into account standard technological constraints like alloy hardness transitions, roll …

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. Achieving this heating temperature is a major ...

When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.

When the objective is to obtain hot-rolled coils (HRC), the slab passes to a continuous or semi-continuous rolling mill, previously subjected to a descaling process by pressurized water. The continuous rolling mill is usually comprised of between 5 to 7 stands, with final thicknesses being comprised between 12 and 1 mm (and even less).
