Sn含量对高磁感取向硅钢热轧板织构的影响

【摘要】 实验室模拟薄板坯连铸连轧(TSCR)流程制造高磁感取向硅钢,借助电子背散射衍射(EBSD)技术对不同Sn含量的热轧板织构进行了研究。研究结果表明:不同Sn含量热轧板表层及次表层均为高斯织构、铜型织构及黄铜织构的混合织构,中心层为{100}面织构;Sn含量为0.1%时,热轧板表层及次表层高斯织构组分最多,取向密度最大,成品磁感最高,达到1.875 T。 

【Abstract】 Texture of grain oriented silicon steel hot rolled by thin slab casting and rolling process(TSCR) in laboratory with different Sn contents was analyzed by electron back-scattered diffraction(EBSD).The results show that the hot rolled slabs with different Sn contents have the same texture,i.e.,Goss,Copper and Brass.Specifically,the texture of core layer is {100};While the hot rolled slab with 0.10% Sn,the surface layer and subsurface layer have a sharpness Goss texture and the finished products h…
