AbstractConsidering the effect of work roll shifting on roll temperature field, a finite difference method of PR format for roll temperature field was presented, which can meet the requirements of accuracy and speed of online calculation. The step-by-step accumulation method was used to simulate the roll temperature field and thermal crown, and the evolution of roll thermal crown in a rolling campaign Was studied. And then, the effects of strip width, rolling rhythm and work roll shifting on roll thermal crown were analyzed. It is found that work roll shifting can disperse the thermal expansion of the roll body especially the edge to make roll thermal contour uniform. The effect of work roll shifting on roll thermal crown is mainly concentrated in regions around twice of roll shifting stroke, and the change range of roll thermal crown is +/- 30 mu m or so in the same roll body location.
