Head and Tail Shape Control in Vertical-Horizontal Rolling Process by FEM

Using 3D rigid-plastic finite element method (FEM), a numerical simulation model for nonsteady state vertical-horizontal rolling process in roughing trains was built and was validated by comparing the simulated values with experimental ones of width and shape of the stock ends. According to certain 2050 roughing processing technologies, the short shape control (SSC) of the stock ends was investigated using the model. Based on the simulated results, a new SSC model was developed. The analyzed results showed that the new SSC model is effective in improving the shape of the stock ends.
