摘　　要：用３０ｔ电弧炉１∶７水模型测定了底吹气体流量、喷嘴孔径及孔数、喷嘴布置方式以及渣对熔池底吹搅拌混合均匀时间的影响。确定了底吹气体流量为１．０～１．５Ｎｌ／ｍｉｎ，喷嘴孔径为　１．０～１．５ｍｍ。回归了各条件下溶液均匀混合时间与气体搅拌能密度的关系。The effect of bettom stirring gas flowrate, diameter and number of nozzles, nozzle arrangement and presence of slag on homogenous mixing characteristics is determined experimentally in water model which is 1: 7 scale of 30t bottom stirring EAF. the appropriate gas flowrate is determined as 1.0～1. 5Nl/min,and the optimum diameter of nozzle as 1.0～1. 5mm, The relationship between solution homogenous mixing time and stirring energy density is calculated in re-gression method.
