Abstrakt: We herein present a mathematical model of hot rolling temperature parameters that factors in how the strip temperature changes in the rolling stand and in the inter-stand gap as well as when metal is transported along the mill train. It factors in the temperature losses caused by thermal radiation and the convective transfer of heat from and to the environment, occurring in the inter-stand gap; temperature losses are also caused by the contact heat transfer from and to the rollers as well as by the heating of the strip in the plastic deformation site. This paper presents the results of using this model to make calculations for a wide-strip hot rolling mill. It illustrates how the model could be used in the algorithm for building a state-of-the-art virtual training simulator.
