Description
"A mathematical model for hydrogen degassing of molten steel in an argon-stirred ladle has been developed and implemented using ANSYS Fluent. Hydrogen removal has been predicted for a range of argon injection flowrates and validated with industrial data from a full-scale vacuum arc degasser. The effect of nozzle arrangement, ladle aspect ratio and the physical properties of the slag layer on degas rate were quantified. By predicting hydrogen removal rate for a given set of conditions, this model may be used as predictive tool to optimise hydrogen degassing efficiency through appropriate design of the ladle and selection of operating parameters."
