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.

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.



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.



3. Scope of Supply


  • Raw material treatment system
  • Internal and external cullet system
  • Glass furnace
  • Tin bath
  • Cold end device
  • Utlity equipemnt
  • Auto control system


4. Raw Materials


Main materials are mainly including:


Silica Sand
Soda Ash
Salt Cake




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.


6.4.Protection Gas Station



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.

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.


Basic Physical and Chemical Characters of Nitrogen and Hydrogen Gas:


Nitrogen gas:


Molecular Mass 28.02
Density under standard state 1.251 kg/m3
Critical Property Temperature -149.1°C
Pressure 3.39 MPa
Density 310.96 kg/m3
Boiling Point -195.8 °C
Specific Heat Capacity Cp 1.047 kJ/kg·°C
Cv 0.745 kJ/kg·°C
Thermal Conductivity 0.233 W/m·k


Hydrogen gas:


Molecular Mass 2.02
Density under standard state 0.090 kg/m3
Critical Property Temperature -239.9°C
Pressure 1.30 MPa
Density 31 kg/m3
Boiling Point -252.2 °C
Specific Heat Capacity Cp 12.269 kJ/kg·°C
Cv 10.132 kJ/kg·°C
Thermal Conductivity 9.469 W/m·k



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.





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
