FE Analysis on Rolls Deformation in Rolling Process of 4100 Heavy Plate Mill

Against 4100 heavy plate miller, a 3-D rolling model involving rolls’ elastic deformation and workpiece’s elastic-plastic deformation is established using large deformation elastic-plastic finite element method. The distributions of the rolls’ bending deformation and the roll gap shape by simulation under the different processes. The results can provide the practical referential value for equipment design and processing setup of heavy plate mill. The FE model may be used to analyze skinning process on off-line.
