利用快冷凝固薄板坯生产单取向电工钢薄板新日本钢铁公司开发了利用高硅钢水浇铸直接生产薄钢坯，并经轧制制取磁性能优良的单取向高硅钢板的方法。该工艺采用规定成分的快冷凝固薄钢坯作为原始材料，通过冷轧至所要求的最终板厚．然后进行脱碳退火，表面涂以退火分离剂之... Production of unidirectional electrical steel sheets by rapid solidification of thin slabs Nippon Steel has developed a direct production of thin steel billets by high-silicon steel casting and the production of uniaxial high-silicon steel sheets with excellent magnetic properties by rolling. The process uses a rapidly solidified thin slab of the specified composition as the starting material and is cold rolled to the desired final slab thickness. Then decarburization annealing, the surface coated with annealing separator ...
