采用冷态模拟实验 ,比较酒钢 5 0t转炉使用普通氧枪喷头与旋流氧枪喷头的溅渣护炉效果 ,结果是在气体流量为 47.6Nm3/h(相当于现场流量 13 0 0 0Nm3/h) ,渣量为 12 % ,枪位为 2 47mm(相当于现场枪位 190 0mm) ,使用旋流喷头溅到炉衬表面的溅渣密度约是普通喷头的 2倍 ;考虑到在实际的溅渣过程是非等温过程 ,对冷态实验得出的最佳溅渣枪位应该予以修正 ,修正系数为 0 .85～ 0 .95 ,本实验取 0 .9。
Cold simulation experiments were carried out to compare the effect of slag splashing on the 50T converter with conventional oxygen lance nozzle and swirl oxygen lance nozzle. The result is that when the gas flow rate is 47.6Nm3 / h (equivalent to the on-site flow rate of 1300Nm3 / h), slag volume of 12%, gun position of 477mm (equivalent to the scene gun position 190mm), the use of swirling nozzle splashing the surface of the slag splashing slag density is about twice the normal nozzle; taking into account the actual spatter The slag process is a non-isothermal process, and the best slag splashing position obtained from the cold test should be corrected with a correction coefficient of 0.85-0.95. The experiment takes 0.9.
