8mm 200Tpd Float Glass Production Line Flint Float Glass for Construction

8mm 200Tpd Float Glass Production Line Flint Float Glass for Construction

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 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.


3.Thickness and Application

4. Raw Materials

Main materials are mainly including:

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.

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.

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.

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

The purpose of glass annealing is to eliminate the internal residual stress and optical heterogeneity of float glass in order to stabilize the internal structure of glass.

Actually, glass annealing process also a cooling process, it need to control the cooling speed according to different thickness and requirements. The residual stress in glass after annealing shall meet the requirement. Meantime, the temporary stress produced during annealing should not be too much, otherwise the glass will crack in annealing lehr.

6.6. Cold-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
