Thin float glass mfr using edge rollers - to keep glass edge close to tank edge and obtain improved optical quality of glass

摘要

Float glass is made in thicknesses 2.5 mm by pouring glass melt at 105.25 poises viscosity so that the melt rings the edges of the float tank with a safety margin or =15 cm and drawing it in the deformable region (105.25-106.75 p) at increased speed so as to keep the edges hugging the tank edges, letting the width reduce the is not 20%. Prod. is suitable for automobile windscreens.
