Float Glass is the ultra-thin glass produced by the float process, and can be drawn to 0.3mm thickness of the product glass. It is a new High-tech, high value-added high-quality glass, with high transmittance, surface roughness, high hardness, good chemical stability, wide application surface and so on.
The application of Float Glass has been involved in six major industries and technology fields:
(1) Electronic information Industry flat panel display panels with substrate glass, such as TN, STN, TFT, LCD liquid crystal display, electroluminescent display (ELD) and field light-emitting display (FED) glass substrate.
(2) watches The masked glass, the instrument and the automobile instrumentation glass, the industrial likeness holographic plate-making glass, the picture machine cover plate glass.
(3) solar power base plate glass, solar cell protection cover plate glass.
(4) Copiers, fax machines and various types of encoder glass.
(5) microscope, medical glass.
(6) Industrial materials with flake glass.
The melting part of the float glass furnace is the part of the melting of the mixture and the clarification and homogenization of the glass solution. The melting part is composed of the melting zone and the clarifying area, and the upper and lower chamber is divided into the top flame space and the bottom kiln pool. The upper space is also called the Flame space, which is filled with flame space by the front face wall, the glass liquid surface, the kiln arch and the chest wall of the kiln wall; the lower pool kiln consists of a pool bottom and a pool wall. In other words, the function of the melting zone is to form the glass liquid by physical and chemical reaction at high temperature, and the function of the clarifying area is to make the bubbles in the glass liquid of the formation quickly and completely discharged, and to achieve the glass liquid quality required for production.
The lower pool kiln of the melting part consists of a pool bottom and a pool wall,
1, flame space is filled with hot flame gas from the heat source, the flame gas will use its own heat to melt the mixture, but also to the glass liquid, kiln wall and kiln. The flame space should be able to meet the full combustion of the fuel, ensure the supply of glass melting, clarification and homogenization of the required heat, and should minimize heat dissipation.
2, pool kiln is a mixture of materials melted into the glass and to clarify and homogenization of the site, it should be able to supply enough to melt completely transparent glass liquid. In order to make the kiln pool reach a certain service life, the wall thickness of the pool is generally 250~300㎜. The bottom thickness of the pool varies according to its thermal insulation condition, and the thickness of the bottom of the insulation zone is generally 300 ㎜.
Compared with other flat glass furnaces, float glass furnace The structure is not too big difference, belong to shallow Chiching pond kiln, but from the scale, float glass furnace scale is much larger, at present, the world float glass melting kiln daily melting amount of up to 1100t above (usually with/expression). The float glass furnace and other flat glass furnaces are different, but their structure has a common place. The structure of float glass furnace mainly includes: feeding system, melting system, heat supply system, waste heat utilization system, exhaust gas supply system and so on.
