采用速比为1.2的异步轧制及常规轧制,将0.30mm厚的工业取向硅钢冷轧至0.10mm;在普通氢气炉中退火对退火薄带的再结晶组织、织构和磁性的研究表明:经异步轧制并在1150℃退火的5h中发生了三次再结晶,晶粒度1～3mm、晶粒取向为｛110｝[001];与冷轧前板材相比,薄带的磁性明显改善:铁攒下降了51%,B8=1.978T,P13/50=0.30mW·g-1P17/50=0.72mW·g-1

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.
