Abstract
The removal of alumina particles from steel is considered for two configurations of a (90–100)-t intermediate ladle. Mass transfer is analyzed on the basis of simultaneous solution of the convective-diffusion equations of the inclusions in the melt and equations describing melt flow within the ladle, taking account of turbulence. An innovation in the assessment of the mass-transfer coefficient between the alumina particles and the refining flux is the concept of wave flow of a thin liquid-flux film as it interacts with the rough surface of the sintered slag. The removal of alumina particles (10–100 μm) from the metal is assessed.
