| 摘 要： | 通过物理模拟测定了RH精炼过程的循环流量、钢包的均混时间、真空室内物料的平均停留时间及容量传质系数，重点分析了RH上升管内的提升气体用喷嘴个数及其布置对上述4个方面特性的影响．结果表明，提升气体用喷嘴个数及其布置对RH内钢水流动有很大的影响，循环流量随喷嘴个数和气泡行程的增加而增大，但均混时间、平均停留时随喷嘴个数和气泡行程的增加而减小．

| Abstract: | The circulation flow rate, mixing time, mean residence time, volumetric mass transfer coefficient of the RH refining process were determined by water modeling. The influence of number and distribution of nozzles in up-snorkel of RH on characteristics of flow was analyzed. The results show that, with the increase of the number of nozzles and the bubble traveling paths, the circulating flow rate increases, but the mixing time and mean residence time decrease with it. |

| Keywords: | RH refining circulating flow rate physical modeling volumetric mass transfer coefficient mean residence time mixing time |
