With combined metal blowing in an oxygen converter, the durability of the purge tuyeres when inert gases are supplied through the converter bottom is less than the durability of the converter lining because of the advanced wear of the tuyeres in relation to the bottom lining and the metallization of the capillaries/channels on the tuyeres with a slag–metal emulsion. To increase the performance of tuyeres, their placement in areas with the least wear of the lining and the avoidance of contact with the slag–metal emulsion are recommended.

安装吹扫装置以向转炉中的熔融金属供应惰性气体

对于氧气转炉中的组合金属吹炼，当通过转炉底部供应惰性气体时，吹扫风口的耐用性低于转炉衬里的耐用性，因为与底部衬里和金属化相关的风口的高级磨损风口上的毛细管/通道与矿渣金属乳液。为了提高风口的性能，建议将其放置在衬里磨损最少的区域，并避免与矿渣金属乳液接触。
