【Abstract】 In order to realize ferritic rolling of IF steel in the 2050 mm hot strip mill of Baosteel, its present finishing rolling force model was modified. The new model deals with the effect of deformation temperature by dividing it into three ranges and introduces a new parameter called ZJJ, which embodies the influence of static softening behavior. The modified model improved the accuracy of forecasted rolling force remarkably.更多还原
