Abstract：

In order to study the effect of temperature on the roller pass changes, the roller temperature field of universal mill was simulated by the finite element Ansys software, the temperature field distribution law in the steady state was obtained, and the changes of roller temperature field under different rolling conditions were studied. The results show that the roller temperature field is cyclical change, comparing with the speed, the effect of flow of cooling fluid on roller temperature field distribution is too bigger, the error between simulated data and measured data is within 5 ℃ which provides the reliability of model. Because the relevant roller pass changes caused by the deformation of rollers, the changes of roller temperature and stress are decreased gradually from center to edge portion. The thermal expansion of internal roller, stress field, external rolling force and friction make the horizontal roller have a larger displacement along the axial and radial of the corner.
