Research and Application of Forging Process for 3800 mm Rolling Mill Backup Rolls
The diameter of the forging of 3800 mm rolling mill backup roll exceeds Ø2300 mm,the core of the steel ingot is difficult to compact. By means of process technology research and numerical simulation demonstration,a composite forging main deformation process of"upsetting-WHF drawing+upsetting-FM drawing"has been determined. After the production validation,the forging process is proven to be reasonable and feasible.
