Problems solved by technology

Because float glass manufacturers need to adjust product specifications frequently according to market demand, this requires a large distance between the glass ribbon in the tin bath and the edge of the tin bath, resulting in a large area of ​​tin liquid surface that cannot be covered by the glass ribbon. We refer to the tin liquid surface in the tin bath not covered by the glass tape as the exposed tin liquid surface in the tin bath, and the exposed tin liquid surface in the tin bath will continuously evaporate the tin liquid, forming a large amount of tin in the tin bath. Steam, tin vapor is oxidized and drips onto the upper surface of the glass ribbon or condenses into tin droplets and then drips onto the upper surface of the glass ribbon, resulting in tin defects and affecting glass quality, etc.
[0003] The inventor found through searching that those skilled in the art have not yet proposed a method to solve the above technical problems. Therefore, how to propose a method for reducing tin defects in glass products has become a long-term technical appeal for those skilled in the art

Abstract

The invention discloses a method for reducing tin defects in a glass product, relates to the technical field of glass production, and aims to assemble an exposed tin liquid level graphite cover plate(4) matched with a tin liquid tank (7) according to the shape and size of the surface area of exposed tin liquid (6) in the tin liquid tank (7), cover the exposed tin liquid level in the tin liquid tank and reduce the exposed area of the tin liquid in the tin liquid tank to the greatest extent. The method has the advantages that the operation steps are simple, the use effect is good, and the method is suitable for large-scale popularization and application. The tin evaporation is effectively reduced, the internal space environment of the tin liquid tank is improved, and the quality of the glass tape is improved.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a method for reducing tin defects in glass products. Background technique [0002] It is known that with the development of the glass production and processing industry, especially the increase in the amount of electronic glass, the quality requirements of the original glass are getting higher and higher. Taking float glass as an example, the main reason affecting the quality of float glass is currently One of these is tin defects. Because float glass manufacturers need to adjust product specifications frequently according to market demand, this requires a large distance between the glass ribbon in the tin bath and the edge of the tin bath, resulting in a large area of ​​tin liquid surface that cannot be covered by the glass ribbon. We refer to the tin liquid surface in the tin bath not covered by the glass tape as the exposed tin liquid surface in the tin bath, and the...
