Continuous extrusion process and quality control of 425/630mm ultra wide copper strip blank
The continuous extrusion process of 425/630 mm ultra wide purple copper strip was studied and the forming process was simulated.The results showed that:the 425 mm wide straight copper strip formed by one extrusion had a uniform and fine microstructure,with an average tensile strength greater than 210 MPa;The performance was ideal and suitable for subsequent large deformation rolling processing of billets;The mechanical analysis of the continuous extrusion model was carried out,and the theoretical values obtained through calculation were similar to the simulation results of Deform-3D soft-ware,with small errors.The numerical simulation model is feasible.
