Custom Dimension Float Glass Production Line Deep Processing Glass Production


1. Brief Description

JEFFER Engineering and Technology Co., Ltd has already designed and completed equipment supply over different hundreds glass plants in China and abroad.

Glass melting is the most important process in glass production, it is a forming process where the batched materials form a qualified liquid evenly with no bubbles under high temperature heating.

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.

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 the upper space of tin bath, it must be full filled with a protection gas.
Normally, Nitrogen gas (N2) and Hydrogen gas (H2) gas are to be used as protection gas. Which is mainly for preventing or reducing the oxidation of metallic tin liquid.

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
