摘　　要：对2250 mm热轧生产线生产的取向硅钢热轧钢带的合金体系进行了设计,制定了合理的加热制度和热轧轧制工艺。对添加稀土元素Ce的取向硅钢铸坯和热轧钢带进行了分析,探究了稀土元素Ce对取向硅钢低倍组织、热轧织构及成品磁性能的影响。结果表明,稀土元素Ce能够细化取向硅钢连铸坯低倍组织和热轧显微组织,提高取向硅钢成品磁性能。Alloy system of hot rolled oriented silicon steel strip produced by 2250 mm hot rolling line was designed,and a reasonable preheating and hot rolling process were formulated.The oriented silicon steel billet and hot rolled strip with the addition of rare earth element Ce were analyzed,and the effect of Ce on microstructure,hot rolled texture and magnetic properties of finished products were investigated.The results show that the rare earth element Ce can refine the microstructure of the continuous casting billet and hot rolled strip,and improve magnetic properties of oriented silicon steel products.
