Method and apparatus for molten metal flow diffusion in a float glass tank

摘要

A method and apparatus for reducing longitudinal distortion in float glass is disclosed. A beam or barrier having cross-hatched grooves is installed below the advancing float glass ribbon in a float glass-forming chamber. The barrier acts to divert or diffuse laterally the molten metal which is being drawn by interfacial drag with the bottom surface of the glass. The diffusion evens the heat on the undersurface of the glass and reduces glass distortion.
