Abstract

Abstract

A three-phase flow mathematical model of argon/liquid steel/slag for a 180 ton ladle was established by using the multi-phase flow volume method according to design parameters of ladle. The interface behavior and mixing phenomena of three-phase flow in the process of bottom blowing argon in the ladle were simulated by CFD software Fluent. Based on the theory of hydrodynamics, the effects of arrangement of double permeable bricks and flow rate of bottom argon blowing on the velocity field, behavior of steel-slag interface and mixing time in ladle were calculated and analyzed. The results show that in the process of bottom argon blowing, the arrangement of double permeable bricks has a great influence on flow field in ladle, and the flow rate of bottom argon blowing has a great influence on behavior of steel slag interface and mixing time. When the angle between two permeable bricks is 135°, the distance from ladle bottom center is 0.6R, and argon flow rate is 600 L/min, flow field distribution in the ladle is better, which is beneficial to improve stirring efficiency of molten steel.
