Toughened glass cover made of float glass: The forming process of float production is completed in a tin trough fed with protective gases (N2 and H2). The molten glass flows into and floats on the surface of the relatively dense liquid tin from the tank kiln. Under the effect of gravity and external tension, the liquid tin is spread and spread out on the surface of the liquid tin to form a flat, hardened and cooled upper and lower surface and is led to the transition roll table. Roller of roller table rotates, pulls glass belt out of tin trough and enters annealing kiln. After annealing and cutting, flat glass products are obtained.

Compared with other moulding methods, the advantages of float method are: suitable for making high-quality flat glass with high efficiency, such as no ribs, uniform thickness, flat upper and lower exterior and parallel to each other; the scale of production line is not limited by moulding method, and the energy consumption per unit product is low; the product utilization rate is high; it is easy to handle scientifically and realize full mechanization and automation, and the labor output rate is high successively; The operation cycle can be as long as several years, which is conducive to stable production. It can provide suitable conditions for on-line production of some new varieties, such as electro-floatation reflective glass, spraying film glass during annealing, cold end surface treatment, etc. Toughened glass cover made of Gefa glass: Gefa is also known as Gravelberg Pinafar, also known as Deep Pool Pinafar. It is an improvement of Shallow Pool Pinafar by Belgians.
