The molding process of float production is completed in the tin bath with protective gas (N2 and H2). The molten glass flows continuously from the kiln 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 tin liquid surface, forming a smooth upper and lower surface, hardening, cooling and then being led to the transition roller table. The roller of the roller table rotates, pulls the glass belt out of the tin trough and enters the annealing kiln. After annealing and cutting, the flat glass product is obtained. Compared with other forming methods, float method has the following advantages: it is suitable for high-efficiency manufacturing of high-quality flat glass, such as no ribs, uniform thickness, flat upper and lower surfaces, parallel to each other; the scale of the production line is not limited by forming methods, low energy consumption per unit product; high utilization rate of finished products; easy to scientific management and full realization. Mechanization, automation, high labor productivity; continuous operation period can be as long as several years, conducive to stable production; can provide suitable conditions for on-line production of some new varieties, such as electrofloatation reflex glass, annealing sprayed glass, cold end surface treatment.
