摘　　要：上海市于１９９２～１９９３年在上钢五厂的１５ｔ复吹转炉上完成了铬矿、氧化镍、铁矿的熔融还原工业性试验，炼成了Ｃｒ１３、Ｃｒ１８Ｎｉ８两种不锈钢母液和铁液。不锈钢母液的熔融还原以含碳铬矿团块、氧化镍矿冷料入炉，过程速率平均为０．１６～０．２５［％Ｃｒ］／ｍｉｎ；铁矿的熔融还原以巴西铁矿氧化球团为原料，冷态入炉，反应速率常数在０．１ｋｍｏｌ（Ｏ＿２）／［（％ＴＦｅ）·ｍ￣２·ｍｉｎ］左右。试验中，二次燃烧率达２４％～４８％，二次燃烧热能利用率为８０％。通过试验，建立了监察渣况的有效手段，掌握了各种参数的合理匹配关系。During 1992～1993,a 15 t combined blowen converter was used to run the pilot test of smelting reduction of Cr-ore, Ni-oxide and iron ore at Shanghai Steel Works No,5.Two kinds of stainless steel master material, Cr13, Cr18Ni8 and hot metal were obtained. The process for stainless steel was adopted the carbon bearing Cr-ore lump ard Ni-oxide. The resulting rate in average was found to be 0.16～0.25%/min For the process of hot metal, the iron-ore pellets produced by Brazil as raw material were added in the converter in cold state, The average reaction rate was shown to be about 0.1 kmol(O_2)/[ (%TFe)·m￣2·min].During this pilot test,the post combustion ratio reached 24%～48%, and its heating efficiency was 80%. Through this pilot test,the effective mean to monitor slag behaviour was established and an operating procedure to match all the parameters was reasonably optimized.
