摘要 |
<p>Provided are a vacuum-degassing method and vacuum-degassing device having superior efficacy in the vacuum-degassing of molten glass; more specifically, provided are a method for vacuum-degassing of molten glass and device for vacuum-degassing of molten glass whereby the occurrence of reboil bubbles is effectively suppressed. A method for vacuum-degassing of molten glass by melting raw glass material, which becomes silicate glass, and allowing the molten glass to flow to a passage within a vacuum-degassing tank the interior of which is held in a depressurized state, the method for vacuum-degassing of molten glass being characterized in that the vacuum-degassing is carried out under conditions satisfying equation (1) at the base of the vacuum-degassing tank. SS=pSO2/Pabs2 in the molten glass; pSO2 is the partial pressure (Pa) of SO2; and Pabs is the pressure (Pa) of the base of the glass passage in the vacuum-degassing tank.</p> |
