本文论述了利用氢等离子体的高温和高还原性,使铬粉的还原过程处于高温悬浮状态,对铬粉进行瞬间脱氧的研究。应用氢等离子体进行还原的同时,解决了以下问题:避免高温烧结和产物重氧化;最大限度减少超细铬粉的生成;使超细铬粉与产品铬粉分离,达到脱氧的目的。铬粉经还原后,其氧含量由0.7～0.9％降低到0.2％以下;同时其它杂质含量亦有降低。本工艺无环境污染。 This paper discusses the use of hydrogen plasma high temperature and high reducibility, the reduction process of chromium powder in high temperature suspended state, the instantaneous deoxidation of chromium powder research. Application of hydrogen plasma reduction at the same time, to solve the following problems: to avoid high temperature sintering and product reoxidation; minimize the formation of ultra-fine chromium powder; ultra-fine chromium powder and chromium products separated to achieve the purpose of deoxidation. After the reduction of chromium powder, the oxygen content decreased from 0.7 to 0.9% to below 0.2%; meanwhile, the content of other impurities also decreased. This process has no environmental pollution.
