Influence of an Induction Furnace’s Electric Parameters on Mass Transfer Velocity in the Liquid Phase

Comprehensive analysis of the chemical phenomena taking place in the liquid metal/gaseous phase systems typical for metallurgy requires knowledge of the mass transfer phenomena occurring in both the said phases. This results from the fact that in heterogeneous systems, the components of the individual phases react with one another only after penetrating the interface. The parameter characterising the mass transfer velocity in the given phase is the so-called mass transfer coeffi cient. Knowing its value with reference to both phases as well as knowing the constant velocity of the reaction taking place in the interfacial area enables calculation of the general mass transfer coeffi cient values characteristic for the given process but also identifi cation of the stages determining the coeffi cient. This paper is an analysis of the results obtained under the tests aimed at determination of the impact exerted by the selected electric and geometric parameters of the furnace on the mass transfer coeffi cient for an induction-stirred liquid metallic phase.
