Abstract
A process and apparatus for improving the removal of gaseous inclusions from molten materials is disclosed. The inclusions, e.g., seeds or bubbles, are removed by applying vibrations to a restricted zone for discharging molten material from the melting tank. The seeds are slowed during a 'pile up' in the restricted channel and are more easily brought to the surface of the molten material.
