摘要
采用光学显微镜和X射线衍射仪研究了常化退火处理对无取向硅钢热轧板和成品退火板显微组织和织构的影响。结果表明:常化退火处理消除了热轧板中的变形组织,促使变形晶粒完成再结晶;常化退火处理使高斯织构和立方织构易通过再结晶在变形带内形核和长大,可显著降低成品退火板的{111}和{112}不利织构组分的占有率,提高{100}和{110}有利织构组分的占有率,从而有利于提高无取向硅钢成品板的磁性能。
The effect of normalizing annealing treatment on microstructure and texture of non-oriented silicon steel hot rolled plates and final products were investigated by means of optical microscope and X-ray diffractometer analysis. The results show that the deformed microstructure of the hot rolled plates transformed into recrystallized grain after normalizing annealing treatment. The grains of Goss texture and cubic texture crystallographic orientation were formed and grown by recrystallization in the deformation bands. The intensity of { 111} and{ 112} unfavorable texture of the final products was decreased, and intensity of the { 100} and { 110} favorable texture was increased significantly. So the magnetic properties of the non-oriented ＂silicon steel final products were improved obviously.
