On-line production method of glass plate product

Abstract

The invention relates to a method for producing glass board products online, which aims to solve the problems of high equipment investment and high production cost of the prior method. After melting liquid glass flowing out form a glass furnace is shaped by a flat board glass shaper, glass boards are cut at the temperature from 550 DEG C to 900 DEG C, and heat processing or after-shaped heat processing is carried out to the glass boards. The glass boards are cut at the temperature from 550 DEG C to 900 DEG C, and the solid plastic temperature sections of the glass boards are cut by an online synchronous cutter which comprises a transverse cutting knife and a longitudinal cutting knife or a model cutting knife with the same size and shape as a processed glass product. The glass board products are made of plane steel glass, curved-surface steel glass, thin reinforced glass, hot-bent glass or curved-surface doubling glass. The invention can save the investment on preprocessing equipment, simplify production technology and obviously save baking expense, and has the advantages of low investment and low cost.

Description

technical field [0001] The invention relates to a glass production technology, in particular to an on-line production method of glass plate products. Background technique [0002] Glass plate products are glass products produced by using glass plates as raw materials. The current method used is to cut the glass plate at room temperature, edge grinding, heat treatment at 720°C or heat treatment after forming. Made of tempered glass or hot bending or hot bending laminated glass. [0003] At present, the common production methods for producing toughened glass from flat glass are: cutting, roasting and heat treatment. Among them, the heat treatment is to cool the formed glass running on the roller table with high-speed air after roasting, and the equipment used is called a roller table tempered glass heat treatment device. The difference between the production method of curved tempered glass and flat tempered glass is that it needs to be molded after firing and before heat tre...

Problems solved by technology

[0004] The inventors have found through research that: pre-production treatment and roasting of glass plate products requires a large number of equipment and manpower, and the heating process needs to consume a large amount of heat, which makes the production cost high. Among them: taking 5mm thick glass products as an example, the cost is as high as 39 yuan / square meter, a medium-scale production line requires an investment of 1.2 million yuan
