摘　　要：通过分析影响出钢口寿命的因素和损毁原因,从减少钢水和炉渣的摩擦损毁及机械冲刷破坏、钢水和炉渣的高温溶解及化学氧化浸蚀等几方面制定措施,出钢口平均寿命由193炉提高到345炉、铁合金消耗降低约3.5%,取得了良好的效果。并设想了一种水冷长寿命出钢口,以期实现出钢口寿命与转炉炉龄同步的生产需求。By analyzing the factors which affect the life of taphole and relevant reasons,it takes measurement of reducing friction and mechanical erosion,high temperature resolution,and chemical oxidization by molten steel and slag,the average campaign life will be increased to 345 heats from 193 heats,ferroalloy consumption is reduced 3.5%.A new water-cooled long campaign-life taphole is also envisaged which can achieve same working life with BOF iteself.
