本发明是关于用连铸坯生产无取向硅钢片的方法。原来,无取向硅钢片的生产方法是将转炉冶炼的钢水出钢后,经过脱气,添加铁合金等来调整成份。然后。将模铸得到的钢锭进行初轧开坯,或把连铸生产出来的板坯直接冷到常温,再在加热炉内加热到高温。长时间保温后,接着经热轧,冷轧工艺制成无取向硅钢片。就是说,为了热轧和得到电磁性能,原来将板坯直接冷到常温的方法就需要消耗大量的热
The present invention relates to a method of producing a non-oriented silicon steel sheet by using a slab. It turned out that the non-oriented silicon steel production method is the converter steel smelting after tapping, after degassing, adding ferroalloy to adjust the ingredients. then. The ingot obtained by die casting is subjected to initial rolling and blooming, or the slab produced by continuous casting is directly cooled to normal temperature and then heated to a high temperature in a heating furnace. After a long time insulation, followed by hot-rolled, cold-rolled non-oriented silicon steel sheet made. That is, in order to hot-roll and obtain electromagnetic properties, the original method of slab directly cooled to room temperature requires a large amount of heat
