1. Brief Description
In 1965, China started to research and develop its own float glass technology and successfully put into production and exported the float glass products and technology to the world.
Nowadays, the international glass new technology is developing in the fields of energy, materials, environmental protection, information, biology. Developing new technology by changing the external and internal performance of glass product, it allows the glass product having excellent function of strength, energy saving, thermal insulation, fire resistance, sunlight protective......etc.
The float glass has a flatness surface, excellent optical performance, no distortions, due to its good quality, the yield float glass can be used for deep processing fabrication.
Because the glass liquid forms on the metallic tin liquid surface, it could achieve a high grade double faced fired polishing glass surface. The parallelism and flatness of float glass are as better as mechanical polishing effect, but it has a better mechanical capacity and chemical stability than mechanical polishing glass.

4. Raw Materials
Main materials are mainly including:
Auxiliary materials as the important raw materials, it mainly includes:
5. Technical Flow Chart of Float Glass Line
6. Main Equipment Description
6.1 Batch Plant
For batching and mixing the raw materials.
The melting tank is key part of glass production line, the refractory materials quality is very important.
6.3 Tin Bath
Glass liquid float on the metallic tin, through stretching, forming, polishing and cooling processing, a qualified glass plate is formed and its temperature reduces around 600°C, the transition roller will send the plate to annealing lehr.
6.4.Protection Gas Station
The protection gas station shall operate continuously to produce and supply the required gas for tin bath.
Tin is easy to reaction with oxygen, sulfur under high temperature and form an oxide, its oxide (SnO2, SnO) will seriously pollute the glass liquid, this will affect the quality of the glass.
Normally, Nitrogen gas (N2) and Hydrogen gas (H2) gas are to be used as protection gas. Which is mainly for preventing or reducing the oxidation of metallic tin liquid.
In order to overcome the air and oxygen brought through the entering of the glass liquid and inert gas itself, a center percentage of hydrogen gas shall be added into nitrogen gas.
6.5. Annealing Lehr
In glass technology, annealing means to put the glass into the annealing lehr for a certain time or reduce the temperature with a slow speed, so as to no additional permanent stress or temporary stress will produce. Namely, annealing also means a process which will reduce or eliminate the thermal stress of glass.
When the heat treatment of glass is under taking between normal temperature and softening temperature, the structure and property of glass will change obviously, such as stress, phase splitting, devitrification, etc.
