FLOAT GLASS MELTING FURNACE AND METHOD FOR FLOAT MELTING OF GLASS

摘要

PROBLEM TO BE SOLVED: To make a float glass melting furnace of the kind described above, in which the danger of generating the float bath air bubbles opened downward in the glass to be floatingly melted is definitely reduced.;SOLUTION: In the case of the float glass melting furnace for a float glass perfecting apparatus, which furnace is provided with a lower easing housed therein with a multiplicity of lower blocks placed to border on each other, is formed with a bath region for housing molten tin above the lower blocks at this time and is extended with the bath region between a bath inlet and a bath outlet, at least portions of the lower blocks are covered by covering materials consisting of tungsten or tungsten alloys according to at least the regions on the surface facing the bath region and the regions of the covering materials extend to the transportation direction of the glass starting from the bath inlet.;COPYRIGHT: (C)2003,JPO
