摘要

A three-dimensional mathematical model for the molten steel flow in a degasser during the RH refining process has been proposed and developed. The physical characteristics of the process, particularly the behaviour of gas-liquid two-phase flow in the up-snorkel and the momentum exchange between the two phases are considered. The ladle, snorkels and vacuum vessel are regarded as a whole in the model, and the gas-liquid two-phase flow is treated and described on the basis of the two-fluid model and using the especially modified two-equation kappa-epsilon model. The details of the model are presented.
