The bubble removal from glass melts in a rotating cylinder
Original language description
The goal of this work is to present results of the mathematical modeling of bubble behaviour in the centrifugal field. The multicomponent bubbles were examined under different conditions. The effect of the cylinder rotation velocity, the degree of its filling by the melt, the cylinder radius, temperature, the bubble size and the bubble initial position in the cylinder on the bubble removal time were studied. The results show that the bubble removal under effects of centrifugal force is a complicated process affected by several mutually contradicting factors. The most problematical is the removal of small bubbles having size under 0.2mm. The very small bubbles are completely dissolved in the melt, but the complete dissolution is a slow process. The searching for optimum conditions of the centrifugal fining needs to get rid of small bubbles by melt pretreating or to inhibit the bubble partial dissolution at higher rotation velocities.
