Tin bath atmosphere control system and float glass tin bath

Abstract

The invention provides a tin bath atmosphere control system and a float glass tin bath. The tin bath atmosphere control system comprises an oxygen content probe, a protection gas supplying pipeline and a controller, wherein the oxygen content probe is used for detecting oxygen content and is arranged in the tin bath; the protection gas supplying pipeline is used for supplying protection gas into the tin bath; the controller is used for controlling the content of hydrogen gas in the protection gas in the tin bath through controlling the protection gas supplying pipeline in real time according detection information of the oxygen content probe. According to the control system provided by the invention, a nitrogen-hydrogen ratio is adjusted by the controller in real time according to the measured concentration of oxygen in tin liquid and/or a space of the tin bath, a reducing atmosphere of the tin bath is strengthened directly aiming at oxidization and reduction properties on tin and oxygen interfaces and reaction of the hydrogen and the oxygen is promoted to be efficiently and rapidly carried out; the content of the oxygen in the space of the tin bath and the tin liquid can be effectively reduced and oxidization of the tin liquid is reduced so that the aim of improving tin impregnation of glass is realized.

Description

technical field [0001] The invention relates to the technical field of designing float glass forming equipment, and in particular relates to a tin bath atmosphere control system. The invention simultaneously designs a float glass tin bath. Background technique [0002] The forming process of float glass is completed in a tin bath filled with a hydrogen-nitrogen mixed protective gas. Molten glass flows continuously from the tank furnace and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the molten glass is spread and flattened on the surface of the tin liquid to form the upper and lower surfaces. Compared with glass made by other molding methods, float glass has the advantages of no ribs, uniform thickness, smooth upper and lower surfaces, and parallel to each other. [0003] The tin bath will inevitably infiltrate air or bring a small amount of impurities such as oxygen and sulfur with the glass liquid during gla...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the amount and proportion of the protective gas filled in the tin bath is not controlled according to the real-time oxygen concentration in the tin bath, resulting in limited protection effect, thereby providing a tin Tank atmosphere control system and float glass tin bath
