由于高炉原料无法完全脱除砷，进入高炉后将导致铁水含砷量过高，从而影响炼钢工艺及钢材质量.通过控制入炉全铁含砷量、铁水温度、碱度、炉顶压力等参数，高炉获得了较高的铁水脱砷率，得到符合生产要求的铁水.试验表明：当入炉全铁砷含量、铁水含硅量、R2、渣比、铁水温度、炉顶压力分别控制在0.015%、0.4%、1.20、400 kg/t、1490℃、220 kPa时，铁水脱砷率最高达67%，铁水含砷量仅为0.007%.

As arsenic can not be fully removed before iron is fed into blast furnace, the high arsenic content in the molten iron distracts steelmaking process and affects steel quality. A favorable dearsenization rate is obtained by controlling arsenic content, molten iron temperature, alkalinity and furnace top pressure. The research results show the maximum dearsenization rate reaches 67 % with arsenic content 0.007 % when the parameters of arsenic content of iron feed, silicon content of molten iron, R2, slag ratio, molten iron temperature and furnace top pressure are controlled respectively as 0.015%,0.4%,1.20,400 kg/t,1 490℃and 220 kPa.
