摘　　要：天钢第二炼钢厂供氧系统供氧强度低,冶炼周期长,限制了铸坯产量的提高。为此进行了供氧系统的改造。文章介绍了改造的重要内容。供氧系统改造后供氧强度增大,每炉缩短供氧时间3min,吹炼平稳,渣中FeO下降,取得了较大的经济效益。Because of the low oxygen blowing intensity, long smelting period and low billet yield, the oxygen system is rebuilt in No.2 Steelmaking Plant of Tiangang Group.The paper introduces the key points of the rebuilding.The result shows the oxygen intensity is increased, oxygen time per converter is shortened by 3 min,the FeO in reduction is reduced and the obvious economic benefit gained.
