Study on Conductivity of Molten Mold Flux

To investigate the effect of electromagnetic field on molten mold fluxMolten mold fluxes, the electrical conductivityElectrical conductivity of the CaO–SiO2–Al2O3–MgO–CaF2–Na2O system was tested by the AC four-electrode methodAC four-electrode method, and the influencing factors and change in the law of conductivity of the molten mold fluxMolten mold fluxes was analyzed. The results show that the conductivity of molten mold fluxMolten mold fluxes increases with the increasing content of Na2O, CaF2, and other components, and the basicity of mold flux. In this work, the electrical conductivityElectrical conductivity of the molten mold fluxMolten mold fluxes is approximately 0.026–0.810 Ω−1 cm−1. For every 0.1 increase in optical basicity, the conductivity increases by about 58.7%. As the temperatureTemperature increases every 25 K, the conductivity increases by about 27.2%.
