我厂现有两座公称容量为15吨的氧气顶吹转炉,71年6月投产,至今已生产四年多。为了适应铁水成份波动大及原材料极不稳定的情况,在吹炼中对氧枪不断进行改进。几年来,我们生产上曾使用过五种不同结构的三孔喷头,其中单三式三种,5°四孔一种,三喉式一种。分析各种不同结构的喷头对吹炼的影响,掌握生产中容易造成喷
I plant two existing nominal capacity of 15 tons of oxygen top blowing converter, put into operation in June 71, has been produced more than four years. In order to adapt to the volatility of hot metal components and the instability of raw materials, oxygen lances are constantly being improved during the blowing process. Over the past few years, we have used five different configurations of three-hole nozzle, of which three single-three, 5 ° four-hole one, a throat-type. Analysis of a variety of different structures of the impact of blowing on the blow, to grasp the production easily lead to spray
