Abstract:The differential temperature rolling method using inter-pass water cooling technology was introduced in this paper to reduce the internal defects of heavy plate,such as shrinkage and cracking,from the continuous casting slab in the hot rolling process. The influence of water cooling process on the temperature evolution and rolling deformation of steel plate was analyzed by numerical simulation and experimental study. The results show that the method of “temperature and deformation control” from water cooling process can effectively increase the deformation permeability inside heavy steel plate and improve its quality. The deformation inside the steel plate during high temperature rough rolling with the inter-pass cooling is significant,but is relatively small during the finish rolling process. In addition,for finish rolling with inter-pass water cooling technology,the rolling force is significantly increased and the rolling load is increased.
