High Precision Rolling Force Prediction Model for Plate Rolling

Based on the Shougang revamping project and plate rolling process, a plate rolling force model of high precision was developed considering the influence functions of deformation area, deformation rate and deformation velocity. Bases on the analysis of influence of residue strain, the residue strain model and dynamic correction of rolling force for different steel grades were obtained. The result of on-line application indicated that rolling force model has good precision of prediction with an error less than 5%.
