Study on crystallizing properties of mold fluxes in electric field
To improve the surface quality of cast strand, crystallizing behavior and properties of mold fluxes in electric field were investigated. The crystallizing properties of mold fluxes in DC and AC electric field were mainly studied. The experimental results showed that the crystal grain size of mold flux gradually grew larger with voltage rising in DC electric field changing from 1V to 3V, while the crystal grain size gradually became smaller with the same voltage increasing in AC electric field. In DC electric field, the grain growth would be promoted, and the grain would be refined in AC electric field. The crystallization ratio of mold fluxes was effectively promoted in both DC and AC electric field. When the voltage of electric field was 0V, the crystallization ratio was only 28.76％. However, if the voltage of DC or AC electric field was 3V, crystallization ratio was increased to 74.35％ and 85.24％ respectively. In electric field, there were no new phases of mold fluxes generated, but the amount of main phases were changed, such as cuspidine (Ca4Si2O7F2) and melilite (Ca2AlSiAlO7) phases became the main phases. The amount of main phases were increased with voltage rising in DC electric field from 1V to 3V, while the amount of main phases were gradually reduced with voltage rising in AC electric field from 1V to 3V.
