Calcium, magnesium, aluminum and silicon building float glass ceramic channel and method for applying same

Abstract

The invention relates to a calcium, magnesium, aluminum and silicon building float glass ceramic channel and a method for applying the same, and belongs to the field of technologies for producing glass ceramics. The calcium, magnesium, aluminum and silicon building float glass ceramic channel comprises a channel body. The channel body comprises a pool bottom, pool walls and a cover plate, a shellis arranged outside the channel body, a discharge pool and a stirring pool are arranged inside the channel body, the channel body is provided with molten glass temperature measuring devices and moltenglass heating devices, a heating space is arranged between the cover plate and the shell and is provided with space temperature measuring devices and space heating devices, all measured temperature data are transmitted to an automatic DCS (distributed control system) so that the temperatures of corresponding locations can be controlled and regulated, and hot air circulating holes are formed in the pool walls. The calcium, magnesium, aluminum and silicon building float glass ceramic channel and the method have the advantages that molten glass crystallization can be prevented and treated by thecalcium, magnesium, aluminum and silicon building float glass ceramic channel with the structure, the calcium, magnesium, aluminum and silicon building float glass ceramic channel is beneficial to improving the clarification and homogenization quality of molten glass, the safety and the stability can be guaranteed by the calcium, magnesium, aluminum and silicon building float glass ceramic channel in glass ceramic float production procedures, the temperatures and the quality of the molten glass can be precisely adjusted, defects of glass ceramic products can be ultimately reduced to a great extent after molding operation is carried out on the glass ceramic products by the aid of a molten tin bath, and the yield can be obviously increased.

Description

technical field [0001] The invention belongs to the technical field of glass-ceramics production, and in particular relates to a channel for calcium-magnesium-aluminum-silicon architectural float glass-ceramics and a method for using the same. Background technique [0002] At present, the calendering and sintering methods are mainly used in the production of glass-ceramics. In 2014, the national production of calendering glass-ceramics reached 14 million square meters, while the output of sintering glass-ceramics was only 150,000 square meters. The market has not yet matured. float glass-ceramic products. As the leading method in the market, the calendering method has many problems: fluoride is generally used as a crystal nucleating agent, which not only erodes refractory materials, but also pollutes the environment; the product surface is not flat, the amount of mechanical polishing is large, and the yield is low; Production of thick and thin plates. The above problems re...

Problems solved by technology

As the leading method in the market, the calendering method has many problems: fluoride is generally used as a crystal nucleating agent, which not only erodes refractory materials, but also pollutes the environment; the product surface is not flat, the amount of mechanical polishing is large, and the yield is low; Production of thick and thin plates

At present, the flat glass and daily glass forehearths commonly used in production do not meet the requirements of the glass-ceramic production process, and the existing glass-ceramic forehearths do not meet the float glass-ceramic production process, and there are local crystallization and easy Defects such as stripes, unstable product quality control, etc., and the structure of the connection between the forehearth and the forming equipment are not suitable for the forming conditions of CaMgAlSi architectural float glass-ceramics, and cannot meet the requirements of CaMgAlSi architectural float glass-ceramics According to the requirements of production technology, a forehearth structure and process control method must be designed on the basis of the existing forehearth to meet the production requirements of float glass-ceramic
