The largest arc length curved tempered glass in the world--arc length of 4500mm curved tempered glass has been successfully off the assembly line. It marks the China enterprise independent research and development of glass bend tempered furnace set a new world record by its own creation, and further consolidate the Chinese glass keep the international leading position in the field of curved toughened glass.

The curved tempered glass which set the world record: The whole piece of glass is 4500 mm long, 2200 mm high and 17.5 mm thick, showing a smooth curved surface and it looks very transparent.

The relevant person in charge said that: the whole piece of glass is actually composed of two ultra clear tempered curved glass, but from the appearance of the two pieces of glass look exactly fit, the alignment is very high. Between the two ultra clear curved tempered glass is thick 1.5 mm PVB film, for bonding effect. But in order to achieve the effect of strict fit, the surface coincidence error of the two pieces of glass of which square nearly 10 square meters must be controlled within 1.5 mm, that’s a great difficulty.

Curved glass is produced by heating the ordinary glass to soften point, and then via the usage of the curved steel furnace according to a certain radius, after rapid cooling, the curved tempered glass formed. It has been widely used as curved glass curtain wall, lighting ceiling, landscape balcony, partition wall, etc. 

In the 1990s, Chinese glass enterprises developed the first curved tempered furnace in China and produced curved steel with a arc length of 2440 mm. In 2005, we set a record of arc length of 3660mm curved tempered glass and kept the leading position.

In recent years, with the development of economic society, the market demand for longer arc curved toughened glass is increasingly strong. After nearly a year of continuously debugging, we successfully completed the upgrade of curved tempered furnace . Now we 
can produce such a large size of the curved glass.
