Recently, slag splashing has been used successfully to enhance the campaign life with reduced gunning in several BOFs. Most of these BOF shops however, determine their own splashing parameters based on results of experiments carried out through trial and error. Current physical modeling research at UMR focuses on trying to provide a more theoretical and mathematical study of the effects of parameters such as the number of nozzles used, the nozzle angles, the momentum flow rate through each of the nozzles, the bath depth, the viscosity of the slag and the lance height on slag splashing. Experiments were completed in a miniature (1/8) scale model of an actual BOF using small boxes installed on the sides of the BOF for collecting the splash and converting results to mass flux under simulated BOF conditions.
