本文叙述了鞍钢150吨氧气顶吹转炉投产以来喷头的使用情况。对于大型转炉来说,喷头还是采用三喉式为好。使用这种喷头,热效率稳定,冶炼强度较高,枪龄也有显著的提高,平均寿命达到260炉,最高650炉,个别的已用了1169次。同时,从本文中也可以得出这样一个结论,即:设计合理的喷枪还需合理的使用。 This article describes the use of sprinklers since the start-up of the 150-ton oxygen top-blown converter at Ansteel. For large converters, the nozzle or the use of throat as well. The use of this nozzle, thermal efficiency and stability, higher smelting power, gun age also significantly improved, the average life expectancy of 260 furnaces, the highest 650 furnaces, some have been used 1169 times. At the same time, from this article can draw a conclusion that: a reasonable design of the gun needs to be reasonable use.
