The heat deformation failure form of workroll bearing chock in Bao Shan steel 2050mm hot strip mill was studied by using finite element method. This phenomenon indicates that the internal friction heat in the bearing is the major heat source that results in temperature rise. With the establishment of reasonable temperature boundary conditions on free and contact surfaces, the heat conduction model of bearing chock was built and discreted. By means of finite element method and three dimensional FEM program, the rules of temperature distribution and heat stress distribution of bearing chock were discussed. Moreover, some suggestions on bearing improvement were brought up.
