电磁搅拌技术是70年代初开发的一项新技术。工业发达国家正在加紧研究、试验,有的已在生产中采用。其主要工作原理是利用旋转磁场或行波磁场使未凝固的钢水产生高速运动,从而使钢坯质量得到改善,浇钢速度得到提高,操作技术也得到放宽。 Electromagnetic stirring technology is a new technology developed in the early 70s. Industrialized countries are stepping up their research and experiments, some of which have been adopted in production. Its main working principle is the use of rotating magnetic field or traveling wave magnetic field so that the solidification of molten steel to produce high-speed movement, so that the quality of the billet to be improved, the speed of steel is improved, operating techniques have also been relaxed.
