摘　　要：分析认为,济钢3200m3高炉铁口喷溅主要原因是碳砖与冷却壁及碳砖与刚玉复合砖之间的缝隙填充不密实以及应力导致的炮泥裂纹等,致使煤气窜漏,铁口喷溅。采用在风口以下铁口区域钻孔灌浆的措施封堵砖缝煤气窜漏;利用专用炮帽,通过铁口通道压入自配浆料,封堵炮泥裂纹,两种方法的结合解决了铁口喷溅的问题。Main reasons of taphole splashing in Jinan Steel＇s 3 200 m3BF are not airtight solid fill of the gaps between carbon brickand cooling wall and carbon brick and composite corundum brick.The other reason is the cracks of taphole clay induced by stresses.They caused the coal gas blowby and taphole splashing.Boring in the taphole area below the tuyere and grouting for plugging thebrick gaps and pressing into self-prepared slurry through taphole by appropriative tapping cap for plugging the cracks of taphole clay.The combination of the two methods solved the problem of taphole splashing.
