Embodiment 1

[0040] Such as figure 1 As shown, the above background technology has mentioned that the traditional production process of ultra-thin float glass, the steps are as follows:

[0041] Step 1: Mix quartz sand powder and sodium carbonate powder evenly, heat at high temperature, smelt into glass water, and then add calcium carbonate;

[0042] Step 2: Pour the liquid glass water into the tin liquid surface in the tin bath to dilute it naturally. After the glass water cools down, it will be in the shape of a glass plate. It will be pulled outward by the edge pulling machine at the edge of the glass plate or formed by itself in the middle of the glass plate. The outward expansion tension makes the middle of the glass sheet thinner and the edge of the glass sheet thicker;

[0043] Step 3: The glass plate formed in the tin bath is first sent to the annealing kiln for annealing through the transition roller table, and then the annealed glass plate is taken out of the annealing kiln.

Abstract

The invention discloses a plate edge thermal cutting process and device in production of ultra-thin float glass, relates to the technical field of ultra-thin float glass, and solves the technical problem of low qualified rate of finished products in annealing and rear-end cutting of ultra-thin glass caused by production defects of float glass. The method comprises the steps: step 1, enabling a glass plate formed in a tin bath to be pulled into transition roller table equipment through a first transition roller of a transition roller table; step 2, enabling the first transition roller to pull the glass plate entering the transition roller table equipment, and performing edge trimming through a cutting device before softening; step 3, separating the edge part and the middle part of the trimmed glass plate; and step 4, annealing the separated glass plate through an annealing section, and performing cutting and packaging the glass plate at a cold end. The method is used for manufacturing ultra-thin glass with the thickness being smaller than 1 mm and has the advantages that the ultra-thin glass is high in qualified rate and good in quality, and the surface of the glass is free of micro scratches.

Description

technical field [0001] The invention relates to an ultra-thin float glass produced by a float forming process, which can be used to manufacture ultra-thin glass with a thickness of less than 1 mm, and specifically relates to a plate edge thermal cutting process and its device. Background technique [0002] The production process of traditional ultra-thin glass and ordinary glass is that the glass is first melted into glass water, and then the glass water is naturally thinned in the tin bath and then artificially drawn into shape. The formed glass plate is sent to the transition roller table, and finally the glass is After the plate is lifted, it is sent into the annealing furnace, which anneals the glass plate. [0003] The existing float glass ultra-thin production line basically follows the original ordinary float process production process. The production process of float glass is to suspend the glass liquid on the tin liquid, and use the self-weight of the glass liquid ...
