Abstract

Abstract

In order to effectively reduce the quantity of slag entrained into ladle during tapping and improve steel quality,a more efficient and low-cost method of slag stopping should be developed.In this paper,numerical simulation for static tapping process under different original molten steel levels has been computed by pressure based segregated implicit solver and k-ε turbulence model in commercial software Fluent 6.3.Under different original molten steel levels in the converter,formation time and movement of vortex flux and the flow characteristics of molten steel during tapping are illuminated in the aspect of numerical simulation by analyzing the flow field of molten steel.The research on slag entrainment during tapping,as well as simulation of tapping and vortex deforming,is expected to provide researchers with useful guidance in exploring advanced slag stopping technology.
