Numerical Simulation of Multi-Phase Melt Flow in a 250t Top-Blowing Convertor
The three-dimensional mathematical model of supersonic oxygen jets on molten steel flow and slag interface distribution has been studied for a 250t multi-hole top lance converter.The interface shape of slag and liquid steel is acquired by the volume of fluid approach.The effects of oxygen flow rate and lance height on the flow of molten bath have been illustrated by their velocity and Mach number distribution.The interface shape between the molten steel and slag is presented under the simulation results of the velocity field distribution.The velocity of liquid steel distribution is not symmetry although the converter with symmetry geometry under oxygen impinging jets.The stirring effects of decarburization and bottom combined blow were not take into account in this paper.The visualization display way for numerical simulation results in different blowing time,lance position and slag layer thickness is convenient.
