Modeling Physicochemical Properties of Mold Slag

Abstract

Abstract This paper deals with the mathematical modeling of physicochemical properties of mold slag such as: viscosity, surface tension, temperature liquidus, basicity. Computer simulation of slag viscosity was made by the Nakamoto structural model. The effect of addition CaF 2 to the mold slag was estimated by using of Urbain model. The results were compared with the results of the experiment. Surface tension for the basic slag composition: CaO - SiO 2 - Al 2 O 3 was calculated with using Nakamoto model. The results of calculations indicate that the content of the SiO 2 lowers the surface tension, but increase the content of CaO and Al 2 O 3 in the slag increases its value. Calcium fluoride (CaF 2 ) reduces the viscosity of the slag. The increase in temperature reduces the viscosity of the slag, simultaneously increasing the surface tension.
