Abstract
In order to control the composition and the inclusion content of a vacuum induction melted maraging steel, an experimental and theoretical study was undertaken to characterize the hydrodynamic behaviour and the transport of elements dissolved in the liquid metal. The bath movement due to stirring forces was calculated with the aid of a model which then determines the transfer characteristics of a solute, due to molecular diffusion, convection and turbulence. Particular attention was given to the phenomenon of volatilization at the free surface. The results obtained using this approach are presented and discussed.
