Physical modelling of slag splashing practice of an 80 t combined blown converter was conducted in this paper. Through measuring the mass flux of splashed slag, the effect of different operating parameters on slag splashing was investigated. By means of variance analysis, the influence significance of different operating parameters on slag splashing was obtained, and the optimal combination of operating parameters were acquired as follows: lance height 600?mm, top gas flowrate 18000?Nm3?h?1, four nozzles lance, bottom nozzle configuration D4, bottom gas flowrate 100?Nm3?h?1, and amount of remained slag 10%. In addition, the relation between the agitation energy of top blow and mass flux of splashed slag was discussed, and the estimation model for mass flux of splashed slag during BOF slag splashing practice was proposed through data analysis. |
