| Abstract: | The pass system of hot rolling of C-profiled steel was studied with FEM simulation. Based on the simulation, the rationality of deformation distribution, the instability of steel rolling in the pass, and the influence of preformed angle of the billet on the bend forming were analyzed. And the pass systems was improved upon the analyses. |
