一、序言随着用户对钢材性能要求的提高,各种钢包精炼法大量推广采用。虽然钢的质量提高了,但从经济观点考虑,精炼炉的设备费用和处理费用却大大增加。因此,国外在继续开发既便宜,效果又好的二次精炼法。日本川崎钢铁公司最近在综合真空脱气法和惰性气体喷吹法二者优点的基础上,开发了一种名为“喷流式搅拌法”的钢包精炼法,即——Pulsating Mixing Process,简 First, the preface As users improve the performance requirements of steel, a large number of various ladle refining method to promote use. Although the quality of the steel has improved, from the economic point of view, equipment costs and processing costs of the refining furnace have increased significantly. Therefore, foreign countries are continuing to develop secondary refining methods that are both cheap and effective. Japan’s Kawasaki Steel recently developed a new ladle refining method called the “jet mixing method” based on the merits of both vacuum degassing and inert gas injection, namely the Pulsating Mixing Process
