一、前言铁水炉外脱硫对提高平炉、转炉等炼钢炉的冶炼效果极为有效。它既省能、省力、又节约资源;因此近几年在国内外得到重视并被广泛采用。其中以向铁水罐中喷吹脱硫剂法最好。这种方法能在短时间内处理大量铁水,脱硫剂的反应效率也高,因此,使用的厂家日益增多。宣钢自1982年至1984年用两年多时间研究铁水炉外脱硫工艺、设计,并在第一 I. Introduction Hot metal outside the desulfurization furnace to improve open hearth, converter and other steelmaking smelting effect is extremely effective. It not only saves energy, saves energy but also saves resources. Therefore, it has been valued at home and abroad in recent years and widely adopted. Among them, it is best to spray the desulfurizer into the hot metal tank. This method can handle a large number of hot metal in a short time, the reaction efficiency of desulfurization agent is also high, therefore, the use of the growing manufacturers. Xuan steel from 1982 to 1984 with more than two years of research outside the furnace hot metal desulphurization process, design, and in the first
