摘要：
By Fluent 6.3, develop a mathematical model of three-dimensional and three-phase flow in the molten bath of EAF with side accessorial oxygen lance to study the transient phenomena of jet impingement on the molten steel and the molten slag. The simulation result shows, the impingement of the supersonic oxygen jet will cause flow of molten steel and the molten slag by inspiring wave of the molten bath surface from the impinged hollow centre to the bath centre, and will cause vortexes under bath which become the centre of molten steel circumfluence. The velocity of flowing molten steel under the oxygen lance or around furnace wall will be faster than that at the center of bath. With oxygen jet enhance, the frequency of the molten bath surface wave will increase, and the center of vortexes will be more apart from the impingement point of jet and will be lower to the bottom of bath, the number of vortexes will increase and the effect of impingement on molten steel will increase accordingly.
