Abstract

Viscosity measurements of the molten oxides and the mold powders during the electric power supply are conducted by the rotational cylinder method in order to examine the viscosity change by the electric power. It is derived from the measurement that the viscosity increases by AC power supply and that viscosity change is increase or decrease in DC power supply. It is cleared by the MD analysis that growing network is the main mechanism of viscosity change in AC power supply. On the other, it is found that the viscosity change is occurred by electrolysis in DC power suuply. These results indicate the possibility of the viscosity control of the mold powder by the electric power.
