摘　　要：通过水模实验研究了210t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50000Nm3/h,底吹流量1000Nm3/h,枪位1700mm,喷孔倾角17°.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°.
