CSP流程试制50W270高牌号无取向硅钢织构的演变
研究了CSP流程试制50W270高牌号无取向硅钢热轧→常化→冷轧→退火过程中织构的演变.利用电子背散射衍射技术对全流程织构进行测量和分析.发现热轧板织构在厚度方向上存在较大差异,表层主要为铜型、黄铜和高斯织构,1/4层存在微弱的高斯织构和旋转立方织构,中心层以γ纤维织构和旋转立方织构为主,还含有较弱的α纤维织构.与热轧板相比,常化板表层和1/4层织构变化不大,中心层旋转立方织构和α纤维织构增强.冷轧板各层均具有α纤维织构和γ纤维织构.与冷轧板相比,成品板各层中α纤维织构基本消失,还出现了立方织构和高斯织构. This article focuses on texture evolution in 50W270 high-brand non-oriented silicon steel produced by CSP in hot rolling,normalizing,cold rolling,and annealing processes.The texture in the whole process was measured and analyzed by electron back-scatter diffraction.It is found that the texture along the thickness direction in hot-rolled strips changes obviously;there are mainly copper,brass,and Goss textures in the surface layer;the 1/4 layer has weak Goss texture and rotating cube texture;γ-fib...
