Tin bath structure for forming high borosilicate float glass

Abstract

The invention discloses a tin bath structure for forming high borosilicate float glass. The tin bath structure for forming high borosilicate float glass includes a processing table, a transition roller table, a flattening device, a slag removal device and a gas conveying device. There is a tin bath on the top surface, and the processing table is fixedly connected horizontally with the transition roller table. The flattening device is installed on the top surface of the processing table and is slidingly connected with the processing table. The slag removal device is also installed on the top surface of the processing table and slides with the processing table. Connection, the gas conveying device communicates with the transition roller table; the low-emissivity coated energy-saving glass is produced by using the tin bath structure for forming high borosilicate float glass. The device of the present invention realizes convenient and stable feeding of molten glass, and the molding glue is neat, reducing waste, and at the same time, the molten glass is evenly distributed and has a high surface smoothness; moreover, the impurities in the tin bath are easy to salvage, and the practicability is strong. The flow rate of sulfur dioxide gas can also be well controlled during output, so as to realize strict control of glass quality.

Description

technical field [0001] The invention relates to the technical field of glass processing and molding, in particular to a tin bath structure for molding high borosilicate float glass. Background technique [0002] The forming process of float glass production is to pass protective gas (N 2 and H 2 ) in a tin bath. The molten glass flows continuously from the tank kiln and floats on the surface of the tin liquid with high relative density. Under the action of gravity and surface tension, the glass liquid spreads and flattens on the tin liquid surface to form a flat upper and lower surface, hardens and cools Afterwards, it is led to the transition roller table. The rollers of the roller table rotate, and the glass ribbon is pulled out of the tin bath and enters the annealing kiln. After annealing and cutting, the float glass product is obtained. [0003] The forming process of high borosilicate float glass production is to pass protective gas (N 2 and H 2 ) in a tin bath. ...

AI Technical Summary

Problems solved by technology

However, the quality of the low-E coated energy-saving glass produced by the existing processing and forming production line is not high. It will be oxidized into tin dioxide and adhere to the glass ribbon, which will deteriorate the quality of the glass. When passing through the transition roller table, the flow rate of sulfur dioxide gas flowing into the roller table is difficult to control, which affects the quality of the glass and is difficult to operate.
