Research on Temperature Difference Controlling of Hot Rolling H-Beam

Abstract:

Complex shape of H-beam section and uneven elimination of heat on the section result in too big temperature difference between web and flange. At the same time,as the roller cooling water forms tank on H-beam web, the section temperature difference further increases. Based on finite element analysis software DEFORM-3D, the FEM model of finished product size of H194×150×6×9 is established. Thermo-mechanical coupled method is adopted to simulate the rolling process of H-beam. The cooling water influence on section temperature distribution, equivalent stress and strain distribution is analyzed. The section temperature change characteristic are studied to provide reference for further research.
