异步轧制速比对3%硅钢织构转变的影响

采用不同的速比对取向硅钢进行异步冷轧，并在常规的生产条件下进行退火，研究速经对织构转变的影响。结果表明；速比对冷轧样品的表面及靠近快速辊侧的区域影响较小，但对心部的影响较大；速比的增加有利于样品两侧亚表层及心部织构组态的改善；

THE INFLUENCE OF MISMATCH SPEED RATIO ON TEXTURE DEVELOPMENT IN CROSS SHEAR ROLLED 3% SILICON STEEL

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.
