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.

Key words: Oxygen Converter, Top Lance Flow Rate of Gas, Lance Position, Mixed Time, Impact Depth

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。
