Title: Production of glass product for grinding, production of glass product, production of glass lump for reheating press and producing device for glass lump
Inventor: TSUKADA SHOGO
IPC: C03B19/10
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To obtain a product small in the variation of the weight and reduced in the generation of grinding scrap with excellent reproductivity by press molding after reheating a glass lump formed from a molten glass to adjust the viscosity to a specific range. SOLUTION: The molten glass supplied from a nozzle is charged into a mold to be formed and slowly cooled to produce the glasss lump. The lass lump is reheated to be controlled to the viscosity of 104-106 poise and press molded with a mold. Because the main surface on the molten glass is formed by the surface tension, the variation of the weight is suppressed. The glass lump small in the variation of the weight is easily obtained by controlling the viscosity of the molten glass. Many glass lumps are produced and stocked to produce many glass products having various kinds of shapes. The temp. of the mold is preferably 600-750 deg.C. The surface roughness Rmax of the mold in the glass lump is controlled to 10-50 μm and the surface roughness Rmax of the mold for reheating press is preferably 1-10 μm.
