| 摘 要： | 在实验室条件下对两种电工钢进行了薄板坯连铸连轧,对Fe-3.2%Si取向硅钢板的铸坯组织、偏析、轧后组织和抑制剂形貌、织构等进行了分析,同时利用热模拟技术测定了Fe-1.6%Si无取向硅钢的CCT曲线,建立了变形抗力模型.结果表明:Fe-3.2%Si取向硅钢铸坯等轴晶比例为35%左右,铸坯表面至中心的碳、硫和磷偏析指数为0.9～1.1,热轧后组织不均匀,分三个区域,热轧带次表层有一定的{110}<001高斯织构存在,织构的组分和传统工艺的基本相同,但织构强度稍弱;给出了Fe-1.6%Si无取向硅钢铁素体区、奥氏体区和两相区变形抗力的数学模型.

| Abstract: | Thin slab continuous casting and direct rolling(CCDR) were performed to two kinds of electrical steels in laboratory.Microstructure and segredation of the cast slab,microstructure of the hot rolled strip, inhibitors morphology and textures for Fe-3.2%Si oriented silicon steel were studied.CCT curves and resistance to deformation model for Fe-1.6%Si non-oriented silicon steel were established by simulation experimental.The results show for Fe-3.2%Si oriented silicon steel,the ratio of equiaxial grains was ab... |
