A rapid prediction method for geometric size in profiled ring rolling process

For the rolling process from rectangular blank to profiled ring, there is a lack of simple and rapid prediction method for geometric size. Based on the constant volume principle and the discrete idea from slab method, a rapid prediction model (RPM) describing the exact geometry of ring is established, and a simplified prediction formula for the section shape of profiled ring in the rolling filling process is proposed. This method is used to analyze the rolling process of typical profiled ring, and the results are compared with the rolling experiment, the finite element model (FEM), and the formula model (FM). The results show that this method has higher prediction accuracy than the constant volume formula method and higher calculation efficiency than the finite element method. The rapid prediction method proposed in this paper is of great significance for improving the analytical efficiency of profiled ring rolling.
