摘要： 研究了取向硅钢制备过程中常见的两种冷轧工艺，主要研究了一阶段冷轧与两阶段冷轧+中间退火工艺对初次再结晶组织及织构的影响.结果表明:采用两阶段冷轧+中间退火工艺制备以Cu2S为主抑制剂的取向硅钢，其初次再结晶平均晶粒尺寸为181μm，高斯晶粒的体积分数为06%，迁移性强的重位点阵晶界(Σ5+Σ9)和高能晶界(20°~45°取向偏差角)所占比例分别为18%和504%.与一阶段冷轧工艺相比，其初次再结晶晶粒较细，且高斯晶核与特征晶界所占的比例较高，有利于高斯晶粒发生二次再结晶.

Abstract: Two common coldrolling processes of grain oriented silicon steel and the effects of the single stage cold rolling and twostage cold rolling with intermediate annealing processes on the primary recrystallization microstructure and texture were investigated. The results revealed that for the grain oriented silicon steel prepared under the twostage cold rolling process with intermediate annealing with Cu2S as the main inhibitor， the average grain size of the primary recrystallization microstructure was 181μm，the volume fraction of Goss grain was 06%， the ratio of coincidence site lattice(CSL，Σ 5+ Σ 9)and high energy grain boundaries(20~45° misorientation angles)which have the higher migration than the conventional boundaries were 18% and 504%， respectively. Compared with the single stage cold rolling process， the primary recrystallization grains of the twostage cold rolling with intermediate annealing were finer; moreover， the proportion of Goss grain and high migration boundaries were larger， which were favorable to the secondary recrystallization occurrence of the Goss grain.
