摘要: 根据鞍钢180 t氧气转炉生产情况,进行氧气顶吹转炉1/15模型的水力学模拟实验,以得出吹炼工艺参数对熔池的影响。结果表明,当模型顶吹气体流量≥15.5 m3/h时,枪位和流量变化对熔池均混时间影响较小;熔池的喷溅量随枪位降低和顶吹气体流量的增加而增加;当气体流量为16.0 m3/h时,熔池的喷溅量较大。

关键词: 氧气转炉, 顶枪流量, 枪位, 均混时间, 冲击深度

Abstract: According to production condition of an 180 t oxygen converter, the hydraulic simulation test of 1/15 model of oxygen top blown converter has been carried to get the effect of blown process parameters on bath. Results showed that as top blown gas flow rate was m 15.5 m3/h the change of oxygen lance position and gas flow rate have little influence on mixed time of bath; with lowering top lance position and increasing top blown gas flow rate the splash amount of bath increased ;and as gas flowing rate was 16.0 m3/h, the splash amount of bath was larger.
