八十年代氧气转炉炼钢技术的最大进展是复吹技术的工业应用及迅速普及。炉底供气向高压、大气量方向发展(日本住友和歌山厂已采用3.9牛/毫米~2的高压供气);供气元件趋向一致,开发了细金属管透气塞供气元件,气量调节的幅度达10～20倍;开发了新气源,1982年发现CO_2气源对喷咀有浸蚀作用而被淘汰,1985年,CO新气源用于工业生产,CO的物理冷却作用为氩气的1.2倍,是一种很有前途的新气源;开发双流道和多流道氧枪,提高热效率,改进转炉精炼机能。
Oxygen converter steelmaking technology in the eighties the biggest progress is the industrial application of compound blowing technology and the rapid popularization. Bottom gas supply to the high pressure, the direction of atmospheric development (Japan’s Sumitomo Wakayama plant has been used 3.9 N / mm ~ 2 high-pressure gas supply); gas components tend to be consistent, developed a thin metal tube breathable air supply components, gas regulation Amplitude of 10 to 20 times; developed a new gas source, in 1982 found that CO_2 gas source on the nozzle has been eroded and was eliminated in 1985, CO new gas source for industrial production, CO physical cooling effect of argon 1.2 times, is a promising new source of gas; the development of dual-channel and multi-channel oxygen lance, improve thermal efficiency and improve the converter refining function.
