THE INFLUENCE OF MISMATCH SPEED RATIO ON TEXTURE DEVELOPMENT IN CROSS SHEAR ROLLED 3% SILICON STEEL
异步轧制速比对3%硅钢织构转变的影响

Commercial grain oriented silicon steel was cold rolled by cross shear rolling (CSR) with different mismatch speed ratios (MSR), followed by industry annealing. The effects of MSR on the texture development were analyzed. Experimental Results show that the MSRexerts little effect on the surface layers and the area near the higher speed roll, but more influenceon the middle section. With increasing the MSR, the texture configuration at the subsurface andthe middle section can be improved significantly. In this process the texture development exhibitsthe "inherence ", but does not influence the final results. The effect of secondary recrystallizationannealing in a CSR process is similar to that in conventional rolling process, i.e. Goss texture grows abnormally, and form the only texture component. Under different MSR being used, thefinal texture and the magnetic properties of samples are resemble, so the MSR can be selectedwithin a certain range.
