摘　　要：分析了炼钢小转炉冶炼含铝钢的难点,探讨了小转炉冶炼含铝钢的操作要点：控制好碳、氧平衡。通过＂高拉补吹＂工艺,将钢水终点碳含量和氧含量控制在一个合适的范围,出钢时通过合理的脱氧合金化控制手法,达到对成分铝有效控制的目的。The paper introduces the difficulty in smelting the aluminum-containing steel and discusses the operation points for small converter to smelt the aluminum-containing steel, that is, controlling balance of carbon and oxygen. By means of the process of high-carbon-withdrawal method for combined blowing to control molten steel end point carbon content and oxygen content within a proper range, which attains the purpose of ingredient of aluminum.
