发明的详细说明: 本发明是没有隆起的表面形状美观的无取向电磁钢板的制造方法。特别是把成份经过适当调整了的硅钢钢水,通过连铸铸成板坯,将这个连铸板坯进行调整热轧,在这个调整热轧板坯之后,通过冷轧、退火的配合,制造出没有隆起的无取向电磁钢板。最近,无取向电磁钢板的制造技术发展很快,特别是由于钢水成份调整,铸锭技术的发展,并且由于这个适用电磁钢板制造技术的提高,使得能够制造出高质量的电磁钢板。
DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for producing a non-oriented electrical steel sheet having a superficial shape without bump. In particular, the silicon steel molten steel whose composition has been appropriately adjusted is cast into a slab by continuous casting, and the continuous cast slab is subjected to hot rolling. After this hot-rolled slab is adjusted, cold rolling and annealing are combined to produce There is no uplift of non-oriented electromagnetic steel. Recently, the manufacturing technology of non-oriented magnetic steel sheets has been rapidly developed, particularly due to the adjustment of molten steel composition and the development of ingot technology, and the improvement of the manufacturing technology of this suitable magnetic steel sheet enables the production of high-quality magnetic steel sheets.
