Three Dimensional Simulation of Edge-Plate Rolling Process Using Rigid Plastic Finite Element Method
초록
In the rolling process, keeping the accuracy of the slab width is a very important problem. So the edge rolling is used with the plate rolling. But in the edge rolling, a local contraction of width, called "width necking", occurs in the top and tail portion of a slab and becomes the cause of crop loss. In this investigation, the three dimensional deformation behavior in the edge-plate rolling is simulated by rigid plastic FEM(PROLL). And the influence of the rolling condition on "width necking" and the accuracy of width is examined.
