一、“六五”期间我国平、转炉炉外精炼取得的成绩“六五”期间我国平、转炉炉外精炼工作处于开拓阶段,主要取得了以下成绩: 1.大力推广普及了钢包吹氩技术钢包吹氩是国外应用最广泛的一种简易炉外精炼手段,我国首先由上钢一厂、鞍钢、上钢三厂等企业研究应用了这一技术。1979年,冶金部在鞍山召开的炼钢总工程师会议上,决定普遍推广钢包吹氩技术。从1980年至1982年每年的炼钢厂厂长工作会议都重点讨论了推广这一技术的问题。目前全国重点钢铁企业已普遍应用了钢包吹氩和部分钢种吹氮,经过吹氩处理的钢由1980年的280万
I. Achievements of China’s Flat and Converter Furnaces During the Sixth Five-Year Plan Period During the “6th Five-Year Plan” period, China’s flat and extra-converter furnace refining work was at a pioneering stage with the following major achievements: 1. Vigorously popularized the ladle argon blowing technology Ladle argon blowing is the most widely used abroad, a simple means of furnace refining, China’s first by a steel plant, Anshan Iron and Steel, Steel Works and other third-party research and application of this technology. In 1979, the Metallurgical Department held a meeting of chief steel-making engineers in Anshan and decided to promote the ladle argon-blowing technology in general. From 1980 to 1982, the annual steel mill director conference focused on the promotion of this technology. At present, the key steel enterprises in the country have generally used ladle argon blowing and nitrogen blowing of some steel types. The steel after argon blowing treatment has risen from 2.8 million in 1980
