The production device of the sheet glass by float method and seal arrangement of the outflow edge of float bath

摘要

Topic Being the new production device of the sheet glass which uses float method, you propose the device which the design of the known seal device which to the outflow edge of float bath is, contact with the glass strip aspect of the combustion gas that tries is obstructed substantially.SolutionsIt was arranged in the glass outflow edge in the device which produces the sheet glass float room and several serial arrangement gap seals (2,2 ') with the float method which is used, the last gap seal of strip traveling direction gap size is 2mm at least, the gases style where the convex surface (7) is provided on the gas exit side, flows out from the seal gap due to this convex surface, (8) the device which becomes to be deflected from the aspect of the glass strip by the Coanda effect.
