一、前言钢包喷粉是70年代发展起来的一项炉外精炼新技术,它设备简单、投资少、见效快。因此,自问世之日起就受到炼钢界的广泛重视。鞍钢第二炼钢厂自1981年11月建成第一台钢包喷粉装置之后,经工业试验与2年多的生产实践表明:工艺可行;效果明显。1983年8月通过了部级鉴定。从1982年4月至1985年5月共处理低合金钢、碳素钢30多 First, the foreword ladle dusting is developed in the 1970s a new furnace refining technology, it is simple equipment, less investment, quick. Therefore, since the advent of the steel industry by the extensive attention. After the first steel ladle dusting device was completed in November 1981 in Anshan Iron and Steel No. 2 Steel Plant, industrial experiments and more than two years of production practice show that the process is feasible and the effect is obvious. August 1983 passed ministerial appraisal. From April 1982 to May 1985, a total of more than 30 low-alloy steel and carbon steel were processed
