1. Brief Description
The name of float glass is because of the glass liquid floating and forming on a metallic tin liquid surface. By using this forming method, it is not need to overcome the gravity of the glass, it can enlarge the width of the glass, improve the speed of stretch, and increase the capacity and scale of production.
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.
2. Characteristic
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.

6. Main Equipment Description
6.1 Batch Plant
For batching and mixing the raw materials. 
6.2 Furance
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
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.
Nitrogen gas, a kind of colorless and odorless gas, which is a main component of protection gas, with a dissociation states in nature. An inert gas as nitrogen gas, it can not combust in air nor dissolve in water, which can prevent the oxidization of metallic tin, and no reaction between nitrogen gas and metallic tin.
Hydrogen gas is a lightest, colorless and odorless combustion gas, mainly existing under compound state. It is a strong reducing agent, with min viscosity, high conductivity and strong chemical activity, which can have chemical reaction with many materials to produce various kinds of hydride.

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.

The purpose of glass annealing is to eliminate the internal residual stress and optical heterogeneity of float glass in order to stabilize the internal structure of glass.
There are two main processes of float glass annealing:
1. Weaken and eliminate the internal stress.
2. Prevent internal stress from producing.

6.6. Colde-end 

It mainly divides into three sections for cold-end part in float glass production line. Details are following:
  • Inspection and pretreatment section
  • Cutting and break section
  • Stacker and packing section
