Commercial grain oriented silicon steel was cold rolled to thickness from 0.06 to 0.10 mm by cross shear rolling, then annealed in vacuum or a hydrogen atmosphere furnace. Deformation textures of the sheets were researched by ODF method and reverse pole figure quantitative analyses. The results indicate that: in the condition of the cross shear rolling, the deformation texture of rolled sheet is generally similar to that of conventional rolled sheet, however, the texture distribution through the thickness is asymmetrical. With mismatch speed ratio increasing, the amount of Goss texture increases. With reduction ratio increasing, the intensity of γ-fiber becomes strong. 展开更多

Commercial grain oriented silicon steels 0 30mm thick were cold rolled to thinner than mm by the cross shear rolling (CSR) and the conventional rolling respectively, then annealed in a normal hydrogen atmosphere furnace. The influence of the process parameters on rolled textures and the magnetic property of thin silicon steel sheets were investigated. The results indicated that the cross shear rolling was beneficial to improve the rolled textures and the magnetic property of the thin silicon steels. The amount of nucleus of Goss grain increased with increasing the mismatch speed ratio; in addition, magnetic properties were improved further with increasing reduction rate, meanwhile, rolled textures tend to well distributed through the thickness of the sheet. 展开更多

The texture inhomogeneity in cross shear rolled grain oriented Si steel was investigated by means of the through thickness texture analysis. For the chosen rolling reductions (55%, 66.5%) and mismatch speed ratios (1.0, 1.1, 1.3), the deformation textures in various thickness layers consist of three major components, i.e. strong γ-fiber, medium α-fiber and weak η-fiber, and they show an asymmetrical distribution throughout the thickness. The effect of reduction on the texture gradient is found to be more significant at and near the center layer; however, the effect of mismatch speed ratio is less important. In most cases, a strong {111}<112> texture component appears in the subsurface layers, that may favour the formation of a sharp Goss texture during the subsequent annealing. 展开更多

The texture change along the normal direction to rolling plane of cross shear rolled commer- cial copper has been studied by means of two step method for ODF caleulation and computer simulation.The texture of cross shear rolling of copper is similar in primary components to that of conventional cold rolling,but the scattering degree and direction of the texture are dif- ferent,due to the residual shear strain change in different position along the normal to rolling plane.It seems that no more effect of the shear strain upon the recrystallization texture. 展开更多

The grain oriented silicon strip was rolled by cross shear rolling (CSR) and then annealed to manufacture non-oriented thin silicon strip of high quality. The recrystallization of rolled 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 better the properties of the non-oriented thin silicon strip are. The optimum annealing schedule is heating at 1 000 ℃ for 1 h in pure hydrogen atmosphere added with H 2S of 0.001 0 %. 展开更多

The Hi-B silicon steels were cold rolled by cross shear rolling (CSR) with different mismatch speed ratio(MSR)s and conventional rolling(CR) respectively, followed by primary recrystallization annealing. The effects of MSR and annealing temperature on magnetic properties of ultra-thin grain oriented silicon steel were analyzed. Experimental results show that, with the increase of MSR, the magnetic properties can be remarkably improved. The higher the annealing temperature is, the higher the magnetic induction and the lower the iron loss in ultra-thin silicon steel is. 展开更多
