Problems solved by technology

[0004] However, the current problem in the field of glass melting is that the glass batch material will volatilize certain components during the process of melting into glass liquid or during the clarification process, such as sodium oxide, sulfur dioxide, boron oxide, lead compounds, water vapor, etc. , especially high borosilicate glass, low melting point glass and leaded glass, etc., the volatilization phenomenon is more significant, and the volatilization amount of some components may even exceed 10% of its content in the glass
[0008] However, none of the above solutions can solve the problem that the volatilized components of the volatile glass will condense on the refractory structure of the furnace during the melting process, causing erosion to the refractory material or the condensation will drop into the glass to form defects.

Abstract

The invention provides a glass melting furnace and a glass melting method. A clarification part of the glass melting furnace contains spray guns, and the spray guns are fixed in the clarification part. The glass melting method comprises the steps of adding raw materials for preparing glass into the glass melting furnace, performing glass melting, opening the spray guns of the clarification part ofthe glass melting furnace in the glass melting process, and obtaining a glass melting solution with the viscosity meeting molding requirements. According to the provided glass melting furnace, by arranging the spray guns in the clarification part, volatile components generated in the glass melting process are blown out of the melting furnace and can be diluted, the concentration of the volatile components in the melting furnace is decreased, the volatile components cannot be condensed on a refractory material of the melting furnace, the service life of the glass melting furnace is prolonged,and the maintenance cost is reduced. At the same time, defects, in the glass, caused by falling due to erosion of the surface of the refractory material cannot occur, and the quality of the glass melting solution is ensured.

Description

technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a glass melting furnace and a method for melting glass. Background technique [0002] In the glass production process, the process of heating batch materials to form glass is called glass melting process. Glass melting is an important stage in the glass production process. The quality and speed of melting determine the quality and output of products. [0003] The melting of glass needs to be carried out in a glass melting furnace. The glass melting furnace is a kind of melting device that the glass manufacturing industry must have. The inner high temperature melts, clarifies and forms molten glass that meets the molding requirements. Glassmaking is 5,000 years old, and the method of making glass, fueled by firewood, by melting glass batches in clay pots has continued for a long time. In 1867, the German Siemens brothers built a continuous coal-fired pool k...
