Mathematical Modelling of Roll Cooling and Roll Surface Stress
ISIJ International, 2005 In a hot strip mill, the quality of the rolled products and the productivity of the mill depend on the efficiency of roll cooling to a great extent. To study the influence of the cooling system on roll performance, a good understanding of the thermal aspects of roll cooling is essential.
