During the sheet rolling process,the CVC rolls will wear out,which seriously affects the quality of sheet processing.For this reason,a method was proposed to optimize the process parameters of grinding force homogenization for the large margin grinding stage of asymmetric wear in the CVC roll grinding process.According to the working characteristics of CVC rolls,the characteristic asymmetric wear roll curves were analyzed;to reduce the fluctuation of the grinding force during the large margin grinding process,the grinding force homogenization model was established,and the grinding force homogenization software was developed.The results show that by using the proposed method,the fluctuation of the grinding force is significantly reduced.
