一、前言喷射冶金技术具有设备简单、投资少、上马快、效果显著等优点,当今国内外冶金工作者已将它作为提高钢质量行之有效的一个重要手段。为了改善特殊钢的质量,提高生产率,降低生产成本,为众多的冶金单位服务,我所从1979年开始试验研究喷射冶金工艺,对喷射冶金的基本原理、冶金条件,喷吹工艺、 I. Introduction Spray metallurgy has the advantages of simple equipment, less investment, quick start-up and remarkable effect. Today, metallurgists at home and abroad have taken it as an important means to improve the quality of steel. In order to improve the quality of special steel, improve productivity, reduce production costs, for many metallurgical units, I started from 1979 experimental study of jet metallurgy, the basic principles of jet metallurgy, metallurgical conditions, injection process,
