摘　　要：对宁钢1号高炉风口出现渣铁熔损和焊缝开焊的情况进行了充分的原因分析,并提出相应的解决措施。分析认为:自产焦炭质量劣化、高炉炉况及气流波动、风口损坏方向壁体温度变化是导致1号高炉风口熔损的主要原因;厂家生产的高炉风口内部焊缝靠前是引起1号高炉风口焊缝开焊的主要原因。There appears slag iron melting loss and weld welding in Ning Gang no. 1 blast furnace tuyere. The causes analysis of this situation is presented and the corresponding solution measures are proposed. The analysis presents the produced coke quality degradation, blast furnace condition and air flow fluctuation, direction of tuyere damage, wall body temperature change are the main reason for No. 1 blast furnace tuyere melting loss. The preceding inner weld of blast furnace tuyere producted by manufacturer is the main reason for the No. 1 blast furnace tuyere open welding seam.
