The rolled strip was divided into a number of strip elements, and the deflection function model was constructed with the third-power spline function and the sine function. Using the minimum potential energy principle, the shape discrimination was transformed into the solution of characteristic values. The influence of different elements on the shape stability of rolled strip was discussed. 相似文献

The grain oriented silicon strip was rolled by cross shear rolling (CSR) and then an-nealed to manufacture non-oriented thin silicon strip of high quality. The recrystallization ofrolled grain-oriented silicon steel into non-oriented silicon steel was studied. For this purpose,CSR is better than conventional rolling, and the higher the mismatched speed rate is, the betterthe properties of the non-oriented thin silicon strip are. The optimum annealing schedule isheating at 1 000 :C for 1 h in pure hydrogen atmosphere added with H2S of O. 001 0 %. 相似文献

The strip flatness and crown control model is the foundation of automatic strip shape control. In this paper, considering the metal transverse flows and the inter stand second deformation, the trip flatness and crown control model has been developed , which can be applied to CVC mills and PC mills as well as normal four-high mills. The strip flatness and crown control model has a high precision, and has been successfully applied to the automatic strip shape control system reconstruction of Tangshan Ganglu 1250mm hot strip plant. 相似文献
