摘　　要：通过降低生铁含硅量,可达到降低生铁生产成本,取得较好经济效益的效果。结合马钢2#2500m3高炉自身炉型特点,通过采取精料入炉,高顶压、高风温、大富氧喷煤,适宜的造渣制度,合理的煤气流分布等强化冶炼措施,使生铁含硅量控制在0.25%～0.3%的水平,取得了较好的综合经济技术指标。Ironmaking cost can be lowered and better economic result can be achieved by reducing silicon content in iron.Based on the features of Masteel's No.2 2500m3 blast furnace and through taking measures such as using concentrated ore,high top pressure,high blast temperature,coal injection with enriched oxygen,suitable slag making and reasonable gas flow distribution,silicon content was controlled at 0.25-0.3% and better economic and technical indicators have been obtained.
