The article presents a reflection on the viscosity of the coating extraction using numerical methods. The viscosity of the coating slag is a factor affecting a high degree on the quality of the ongoing process of refining. Too high a viscosity will restrict the diffusion of impurities from the metal to the slag, in turn, too low a viscosity will cause spreading of slag in the vicinity of the furnace wall, and thus exposing the mirror of the liquid metal which may result in adverse effects of an oxidizing atmosphere. You should also remember that too low a viscosity can increase the loss of metal in the slag as well as hinder its recovery during casting. Using the materials database and numerical methods it is possible to determine the level of selected blends of slag viscosity. Additionally, in order to determine their usefulness in refining the values obtained can be confronted with laboratory tests using derivatograph. On the basis of the designated energy index Ew and mass index r can determine the suitability of a mixture of slag and its impact oxidizing or reducing agents.
