Abstract：The temperature of cold-rolled strip contacting with the shapemeter roll is obviously different in cold reversible rolling’s different passes. Therefore, the temperature field and stress field of shapemeter roll are very instable. Using finite element software ANSYS, the coupled thermo-mechanical model was established to analyze the shapemeter roll’s transient temperature field and stress field in cold reversible rolling process. Analysis results show that the contacting strip’s heat transfers gradually from roll body’s outside surface to inner hole surface in rolling process, and the temperature of roll body’s outside surface right above the sensor rises fastest and attains maximum value of 135℃ after 1940 seconds’ rolling. Because of the thermal contact resistance of sensor framework’s top surface and roll body’s inner hole surface, the sensor’s temperature rises slowly, and the temperature of framework’s top surface attains maximum value of 134℃ after 2280 seconds’ rolling. Shapemeter roll body’s maximum stress occurs at the contact area of roll body’s inner hole surface and sensor framework’s top surface. The maximum value of 301MPa occurs after 940 seconds’ rolling, and it can fulfill the material strength requirement. Comparisons of simulation results with field test data prove the correctness of finite element model.
