Sn含量对高磁感取向硅钢热轧板织构的影响

Effect of Sn content on texture of high induction grain-oriented silicon steel hot rolled

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。

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 1100} ; While the hot rolled slab with 0. 10% Sn, the surface layer and subsurface layer have a sharpness Goss texture and the finished products have a highest magnetic induction intensity which reaches 1. 875 T.
