Flint ISO9001 300tpd 4mm Float Glass Production Line

4mm-10mm Construction and Pioneer Float Glass Production Line and Processing Equipment
 
 
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.
 
 
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:
 

 
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.
 
 
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.
 
Basic Physical and Chemical Characters of Nitrogen and Hydrogen Gas:
 
Nitrogen gas:
 

 
Hydrogen 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.
 
 

 
 
6.6. Colde-end 
 

• Inspection and pretreatment section
• Cutting and break section
• Stacker and packing section
