Overseas JEFFER Flint 8mm Float Glass Making Machinery

2mm-8mm Float Glass Prduction Line Together With Batch Plant, Furnace, Tin Batch
 
 
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 production technology of float glass is the largest scale mechanization and automation methods of production of flat glass production technology at present time.

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.

Main materials are mainly including:
 

 
Auxiliary materials as the important raw materials, it mainly includes:
 

 
 
5.  Technical Flow Chart of Float Glass Line
 

• Qualified batching materials transfer to the furnace for melting.
• Melted glass liquid flows onto tin bath and form a glass plate through mechanical and chemical methods.
• When the temperature of glass plate reduced around 600°C, it will conveyor into annealing lehr and relief the stress.
• After inspection and cutting, the yield glass product conveyors to packing area.

 
 
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

It is a key and one of most important equipment of float glass production line.

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.
 

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.
