5. Technical Flow Chart of Float Glass Line
 

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

The protection gas station shall operate continuously to produce and supply the required gas for tin bath.

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.

Besides the good melting efficient, the bright and clean surface of metallic tin is also another important key to produce good float glass product, So, an inert gas or reducing gas to be adopted for a kind of protection gas to prevent the tin from oxidized.

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.
