摘　　要：以现有取向硅钢热轧板为初始材料,利用金相显微技术对比研究了不同常化工艺对取向硅钢常化板组织的影响。结果表明:取向硅钢经常化后原有的条带组织明显减少,晶粒明显长大粗化,特别是在表层,铁素体晶粒尺寸达到34μm。取向硅钢常化板组织有利于改善后续冷轧轧制和脱碳工艺情况。Using the existing grain-oriented silicon steel hot-rolled sheet as the initial material,the effects of different normalization processes on the microstructure of the grain-oriented silicon steel normalized sheet were comparatively studied by metallographic microscopy.The results showed that the original strip structure of oriented silicon steel was obviously reduced after regularization,and the grains were obviously enlarged and coarsened,especially the grain size of ferrite in the surface layer reached 34μm,and the normalized plate structure of oriented silicon steel was beneficial to improve subsequent cold rolling and decarburization processes.
