Optimalizace úběrového plánu při válcování sochorů v přípravném pořadí Středojemné válcovny s využitím matematického modelování

Abstract

This thesis is follow up with the design of a new shape of groove and subsequent mathematical modeling based on FEM. A total of sixteen variants of the billet passage were proposed and simulated, from which the input data for the DOE planned experiment were obtained. Subsequently, the DOE was evaluated for our responses. The observed responses include the area of the billet on the exit plane in the region of the deformation zone, the rolling force, the effective strain inside the rolled billet and the effective strain of the collar, and the fracture criterion at the bottom of the groove and of the collar. The input billet for simulation is made of chromium-vanadium steel 58CrV4. The end of the thesis is the operational recommendation for designing the optimal setting of the new groove shape.
