摘自《Steelmaking Conference Proceedings》,1990;73:315-318 澳大利亚布罗希尔公司怀阿拉厂有两座125-t顶底复吹转炉。该炉属“欧洲”型转炉,高8.8m,外径6.1m。采用LBE工艺生产,顶吹氧气通过三孔氧枪吹入,氧气流量主要取决于钢水的终点碳含量,一般为20000m~3/h,喷吹时间为20min。 1987年,该厂扩大了钢种生产,研究了以CO_2作为底吹气体生产高质量低氮钢的生产方法。在转炉中,底吹气体喷嘴要经受机械磨损,热磨损和化学侵蚀。喷吹CO_2时,化学侵蚀和反向冲刷是炉衬及喷
Excerpt from “Steelmaking Conference Proceedings”, 1990; 73: 315-318 Two large 125-t top and bottom converters at Brothers Hill in Australia. The furnace is a “European” type converter, high 8.8m, diameter 6.1m. LBE process using the production of oxygen blowing through the top three holes lance, oxygen flow depends mainly on the end of the carbon content of molten steel, usually 20000m ~ 3 / h, injection time of 20min. In 1987, the plant expanded steel production and studied the production of high-quality, low-nitrogen steel using CO 2 as the bottom blowing gas. In converters, bottom blowing gas nozzles are subject to mechanical wear, thermal wear and chemical attack. When CO2 is injected, chemical attack and back flushing are lining and spray
