| Abstract: | Based on the analysis of the process data for producing the non-oriented silicon steel during hot rolling by Six Sigma Quality Analysis Method,it was determined that the heating temperature and margin width of the side guide to the finishing mill were the key factors for causing edge cracks of the hot rolled non-oriented silicon steel sheet.By using the response surface regression analysis method,the related technical parameters for producing the non-oriented silicon steel during hot rolling were optimized and then the edge cracks of the non-oriented silicon steel during hot rolling were greatly reduced. |
