Calculation of temperature and determination of deformation resistance in H-beam rolling: (2) Total change of temperature and deformation resistance

Abstract In this study, a formulation for shuttling temperature drop is developed, therefore the total temperature change in H-beam rolling can be determined, thus enabling the temperatures of the rolled piece before and after rolling at any pass in the continuous rolling process to be obtained. The deformation resistance of a material is a significant parameter influencing the rolling force and torque. The interpolation method is adopted to simulate the true experimental stress–strain curve. By this means the accuracy of calculation of the energy parameters has been greatly improved.
