Tin bath structure for forming of high-borosilicate float glass

Abstract

The invention discloses a tin bath structure for forming of high-borosilicate float glass. The tin bath structure for forming of high-borosilicate float glass comprises a processing table, a transition roller table, a spreading device, a slag removing device and a gas conveying device, wherein the top surface of the processing table is provided with a tin bath; the processing table is horizontallyand fixedly connected with the transition roller table; the spreading device is arranged on the top surface of the processing table and is slidably connected with the processing table; the slag removing device is also arranged on the top surface of the processing table and is slidably connected with the processing table; and the gas conveying device communicates with the transition roller table.The tin bath structure provided by the invention is used for processing and producing low-radiation coated energy-saving glass. The tin bath structure of the invention realizes convenient discharge ofa glass liquid and stable blanking; formed glue is neat and tidy, so waste is reduced; the glass liquid is uniformly distributed, so surface flatness is high; impurities in the tin bath are easy to scoop up, so good practicability is realized; and the flow of sulfur dioxide gas can also be well controlled during outputting, so the quality of the glass is strictly controlled.

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 completed in a tin bath filled with protective gas (N2 and H2). 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.

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.
