一、绪言近年来,广泛采用电磁搅拌装置(以下简称EMS)作为改善连铸坯内部质量的有效手段。电工钢也可通过改善等轴晶率来改善后工序的处理方法,达到降低成本的目的。新日铁広畑制铁所于1977年在板坯连铸机上安装了EMS,结果大幅度地降低了生产成本。本参考资料是以広畑的电工钢的经验为基础整理出来的,作为武钢1号连铸机EMS生产的指南。 I. Introduction In recent years, the electromagnetic stirring device (hereinafter referred to as EMS) is widely used as an effective measure to improve the internal quality of continuous casting slabs. Electrical steel can also improve the processing method of the post-process by improving the equiaxed grain ratio to achieve the purpose of reducing costs. Nippon Steel Corporation installed EMS in its slab caster in 1977, resulting in a significant reduction in production costs. This reference is based on the experience of 広 畑 of electrical steel sorted out as a WISCO No.1 continuous casting machine EMS production guidelines.
