运用电子背散射衍射(EBSD)技术,研究了50W600无取向硅钢在热轧→冷轧→退火工序间织构的演变。结果表明:由于热轧板沿板厚方向的应力场和温度场存在差异,导致热轧板不同层织构类型和强度存在差异;热轧板表层主要存在铜型、黄铜和高斯织构,1/4层织构主要为α纤维织构和较弱的高斯织构,中心层织构较单一,主要为α纤维织构;和热轧板相比,冷轧板各层织构差异较小,为典型的轧制织构(α纤维织构和γ纤维织构);退火板各层都表现为γ纤维织构增强、α纤维织构减弱,旋转立方织构基本消失。 The texture evolution of 50W600non-oriented silicon steel in hot rolling,cold rolling and annealing process was investigated by electron back-scatter diffraction(EBSD)technology.Results show that the hot rolled plate texture types and intensities along thickness direction were different because of the different stress fields and temperature fields.The major texture types in the surface of hot rolled plate were copper,brass and Gauss texture.The texture was composed ofαfibre texture and weaker Ga...

一种使铋收得率不低于70%的含铋取向硅钢冶炼方法,其步骤:常规转炉冶炼并出钢至钢包中;RH精炼处理,其间:控制渣层厚度不低于45mm,且渣成分在:Al2O3:25~35wt%,CaO:40~50wt%,MgO:10~15wt%,且结束时钢水温度控制在1530~1590℃;真空精炼结束后进行镇静;后将铋颗粒与石灰石颗粒混装容器加入钢水中;保护浇注和后工序生产。本发明将铋颗粒与石灰石颗粒混合加入,石灰石在钢液中分解产生的气体不仅可以减缓铋颗粒下沉速度,使铋能够快速扩散均匀,更主要的是还可以强化铋颗粒在钢液中的扩散,最终可获得铋收得率高于70%即在71~75%的理想效果。

热卷箱位于热连轧带钢生产线粗轧与精轧机之间,是热连轧生产中比较理想的中间保温设备。由于取向硅钢变形温度区间较窄,在生产中易出现边裂现象,同时中间坯的边部温度难于得到保证,因此一般不采用热卷箱设备生产,限制了传统热连轧生产线产品开发的品种。通过合理优化热卷箱控制工艺参数,解决了某厂传统热连轧生产线用热卷箱生产取向硅钢的边部质量问题,成功地生产出取向硅钢带。 The hot coil-box is an ideal heat retaining apparatus for hot rolling,lined between roughing mill and finishing mill. But oriented silicon steel has a narrow deformation temperature range,so that the edge crack easily occurs and it is difficult to insure the temperature of the intermediate blank. Therefore,the hot coil-box is rarely used in producing oriented silicon steel,which restricts the product development of the traditional hot rolling line. The article reasonable optimized process parame...
