Float glass processing occupies a dominant position in the world glass industry. After high temperature melting, it flows to the surface of metal liquid, and then it can be separated from the metal liquid after cooling and hardening. Finally, it is a kind of glass formed by cutting. The forming process of float production is completed in the trough of milk protective gas. Float glass is widely used, which is divided into colored glass, silver float glass, float glass (automobile windscreen grade). Super white float glass has a wide range of uses and broad market prospects, mainly used in high-grade buildings, high-grade glass processing and solar photovoltaic curtain wall field.

Float glass processing from the tank kiln continues to flow into and float on the surface of the absolute density of the liquid tin, under the action of gravity and external tension, the liquid glass on the surface of the liquid tin spread, flattened, forming the upper and lower surface flat, hardening, cooling is brought to the transition roll table. The roller of the roll table rotates and pulls the glass strip out of the tin groove into the annealing kiln. After annealing and cutting, the flat glass product is lost.
Float glass forming and other forming methods, its advantages are: suitable for high efficiency manufacturing of high quality plate glass, such as no reinforcement, average thickness, surface flat, parallel to each other. The scale of consumption line is not limited by the forming method, and the energy consumption per unit product is low. The application rate of finished products is high, and it is easy to manage and complete the mechanization and automation of all present, and the rest consumption rate is high. The continuous operation cycle can be as long as several years, conducive to the fluctuation of consumption, can provide suitable conditions for the online consumption of some new types, such as electric float reflection glass, annealed spraying film glass, cold end surface treatment, etc.
