Abstract
A numerical simulation model for vertical-horizontal rolling process in roughing trains is built according to 3-D rigid-plastic finite element method (FEM), which is validated by comparing the simulation results with measured ones of industrial production. The principle of width deviation appearing on head and tail of slab is investigated by the finite element (FE) simulations. A new polynomial short stroke control (SSC) model is developed based on the comprehensive simulation results and the analyzed results show that, at the aspect of width control, the new SSC model is more effective than the two line one.
