组合式氧枪的优点是寿命长,氧流量大,可缩短冶炼时间,在国外得到了广泛的应用。国内引进的50吨奥地利转炉使用的是组合式氧枪。根据我们对奥地利氧枪的解剖,这种枪结构比较复杂,但在二孔中心区(所谓“鼻子”)有很好的冷却,大大避免了目前国内使用的实心氧枪(或称简易氧枪)咬“鼻子”的情况,应该在国内逐步推广。 Combined lance has the advantages of long life, oxygen flow, can shorten the smelting time, has been widely used abroad. Domestic introduction of 50 tons of Austrian converter is a combination of oxygen lance. According to our anatomy of the Austrian lance, this gun structure is quite complicated, but it is well cooled in the center of the two holes (the so-called “nose”), which greatly avoids the current use of solid oxygen lances Bite “nose” situation, should be gradually promoted in the country.
