Abstract

The improvement of mixing conditions in metallurgical vessels is of fundamental importance to increase furnace productivity, steel cleanliness, removal of impurities, and so on. Water modeling has been used to investigate mixing phenomena; however, there is still a need to clarify the role played on mixing time by process variables such as the nozzle diameter to properly represent the real process conditions. In water modeling design, this parameter is usually ignored. The current investigation has found that changes in nozzle diameter affect mixing time; however, the extent of this effect is influenced by nozzle radial position and gas flow rate. The conditions to minimize mixing time with one nozzle and a top layer of 2 pct have also been identified.
