摘要： 通过水模实验研究了210 t顶底复吹转炉底部供气元件的布置方式、顶吹气体流量和顶枪枪位等对熔池混匀时间、冲击深度和冲击直径的影响. 结果表明，各因素对混匀时间、冲击深度和冲击直径的影响不同. 最短混匀时间的操作参数为：底部布置方式A3，顶吹流量50000 Nm3/h，底吹流量1000 Nm3/h，枪位1700 mm，喷孔倾角17°.

关键词: 顶底复吹转炉, 水模型, 混匀时间, 冲击深度, 冲击直径

Abstract: The impacts of bottom tuyeres layout, flowrate of top blowing, lance height and other factors on mixing time, penetrating depth and cavity diameter in a 210 t top-bottom combined blown converter were studied using water model. The effects of different factors on the mixing time, penetrating depth and cavity diameter were not consistent. The operating parameters of the shortest mixing time were obtained as follow: layout A3 of bottom tuyeres, flowrate of top blowing 50000 Nm3/h, flowrate of bottom blowing 1000 Nm3/h, lance height 1700 mm, and nozzle angle 17°.

Key words: combined blown converter, water model, mixing time, penetrating depth, cavity diameter
