Based on the results of water modeling, the influence of the design of the bottom blowing device for the teeming ladle on the efficiency of mass-transfer processes in the liquid melt has been determined, namely, the effect of the bubble-forming chamber design on the duration of the melt homogenization has been determined. The bottom blowing devices equipped with bubble-forming chamber of slit, channel and non-directional types have been studied. According to the research, it was determined that the most effective design of the bubble-forming chamber for bottom blowing devices is the use of non-directional porosity materials. Their use allows obtaining a stable column of small bubbles, thereby reducing the time of homogenization by 14%.
