Abstract
Using hot modeling technique for conditions of combined blowing of the converter bath with feeding of stirring neutral gas through the bottom, the features of chemical and temperature heterogeneity of the melt, features of parameters of the reaction zones formed and mechanisms of macro-physical processes occurring during metal blowing were studied. When processing the obtained experimental data, numerical values of effective diffusion coefficients and thermal diffusivity coefficients were obtained as characteristics determining the possibilities of increasing the efficiency of blowing and mixing of the converter bath. The established features of the converter bath behavior, features of processes in the reaction zone and other areas of the bath during combined blowing confirm the possibility of increasing the efficiency of blowing and mixing of the melt, and, consequently, reducing chemical and temperature gradients.
