摘要

Last month, in our discussion of mold flux properties, we focused on measuring mold flux viscosity and the factors that determine viscosity. This month, we will describe some of the models for the calculation of viscosity. Models for the calculation of viscosity - Several investigators have developed, empirical models for calculating the viscosities of casting fluxes from their chemical composition. McCauley and Apelian~(20) measured the viscosity of 20 moldfluxes within the composition ranges given in Table III. They found that the viscosity at a given temperature can be expressed as a function of the ratio of network forming ions to anions, or as a function of the mole fraction of silicon. Kiboud et al. at IRSID carried out viscosity measurements on a set of 23 synthetic and 22 industrial fluxes within the ranges of composition given in Table III, IRSID's model utilizes the Frenkel equation to correlate the viscosity with temperature and composition:
