摘　　要：通过改善原燃料质量、合理的煤气流分布、提高炉顶压力、降低入炉焦比、富氧、喷煤、高风温协调互补、适当提高炉渣碱度等措施,使唐钢炼铁北区1号高炉生铁〔Si〕有0.68%降至0.45,取得了较好的经济效果。Through improving the quality of raw materials and fuel, optimizing the distribution of coal gas stream, enhancing top pressure, reducing charge coke ratio, harmonizing rich oxygen, pulverized coal rejection and high wind temperature, properly increasing slag basicity, silicon content in hot metal of Tangshan Steel No. 1 BF is reduced to 0.45 % from 0. 68%.
