Method and apparatus for manufacturing glass ribbon on a float bath

摘要

A method and apparatus are disclosed for manufacturing glass ribbon by pouring molten glass onto a bath of molten metal. A portion of the molten metal is withdrawn from the molten bath underneath the molten glass, upstream from the location at which the molten glass forms the glass ribbon. The withdrawn molten metla is entrained by a reducing gas, and heated. The molten metal and reducing gas are introduced into the molten metal bath generally at a side region of the bath.
