中文摘要：

为生产 Fe-6.5wt% 的一个新技术原型由方向性的团结的 Si 电的钢表，在滚动前的热处理，温暖的滚动，并且冷滚动在现在的学习被建议。在滚动和这个技术原型的合理过程参数前的 Fe-6.5wt% Si 电的钢的 formability 被获得。试验性的结果表明 Fe-6.5wt% Si 电的钢的 formability 在滚动前在方向性的团结和热处理的联合下面显著地被改进。没有在完整的滚动期间退火的任何中介，有 0.15 公里，明亮的表面，很少边裂缝，和高滚动产量的厚度的 Fe-6.5wt% Si 电的钢表能成功地用这种技术被制作。方向性的团结的联合，在滚动前的热处理，温暖的滚动，并且冷滚动能为 Fe-6.5wt% Si 电的钢表的高度有效、紧缩的制造作为一个新过程工作。

英文摘要：

A new technical prototype for producing Fe-6.5wt% Si electrical steel sheets by directional solidification, heat treatment before rolling, warm rolling, and cold rolling was proposed in the present study. The formability of Fe-6.5wt% Si electrical steel before rolling and the reasonable process parameters of this technical prototype were obtained. Experimental results reveal that the formability of Fe-6.5wt% Si electrical steel is improved significantly under the combination of directional solidification and heat treatment before rolling. Fe-6.5wt% Si electrical steel sheets with the thickness of 0.15 ram, bright surface, few edge cracks, and high rolling yield can be successfully fabricated using this technology without any intermediate annealing during the whole rolling. The combination of directional solidification, heat treatment before rolling, warm rolling, and cold rolling can work as a new process for highly efficient and compact fabrication of Fe-6.5wt% Si electrical steel sheets.
