摘要

The continuous cast half-finished products quality is in a major part influenced by the lubrication process from the mould, which is influenced at its turn by slag viscosity, resulted from the melting of the lubrication powders. The paper presents the results and conclusions of the laboratory experiments regarding the chemical composition influence on slag viscosity. The research targeted establishing some correlations between the dynamic viscosity and the chemical composition of the slag. For the chemical composition it was chosen as variable factors (representative components) the contents of CaO, MgO, Al_2O_3, and SiO_2 (the last two expressed through Al_2O_3/SiO_2 ratio). The experiments for viscosity were performed on slags at temperatures of 1350 C. Processing the data was performed in Matlab laboratories, obtaining four (4) multiple correlations. The results are presented both in an analytical form and in a graphical form. The use of the obtained relations allows determining slag viscosity with a mathematical error, and using graphical correlations allows establishing the variation area (the limits) of viscosity to the representative components.
