Premium High Purity Graphite Board for Vacuum Sintering Use

Product Description

High Purity Graphite Board Graphite Mould for Sintered Vacuum Furnace

Graphite sheet is made from the domestic petroleum coke and widely used in the metallurgy, machinery, electronics and chemical industry, etc. From the dimension to material selection, our company keeps providing the best for customers. Our graphite plate is manufactured by advanced production technique and equipment with characteristics of good conductivity, high temperature resistant, acid and alkali resistance, corrosion resistance, great resistance to thermal and mechanical shock, and easy processing characteristics.

Our Advantages:

1. Special treatment on graphite plates with longer service life.

2. Various dimensions according to customers' requirements

3. Exact machining accuracy

4. Relevant suggestions based on your condition

5. Stable after-sale service

How to choose the graphite plate?

Customers have various requirements about graphite plates. The working environment, the material, density or other requirements all could affect the selection of graphite plates. You may use graphite plates for electrolysis, thermal conductivity, or applied as the furnace liner, trays, sealing parts, and so on. Our factory will definitely afford your conditions. And our engineers could assist you and provide the best advice for you to choose the appropriate graphite plates, even if you don't know much about the graphite. The most suitable density, grain size, strength, electric resistance of the graphite products will be offered based on your exclusive occasions.

The precautions to extend the service life of graphite plate:

1. When the current of the graphite plate becomes larger, the surface temperature of the graphite plates will be higher. Under such climate, we advise to use the low surface load power.

2. It's much better to parallel the graphite plates rather than connect in series.

3. After the graphite plates are heated in air, the surface forms compact silicon oxide film to resist oxidation. Kinds of surface coating have been applied to avoid the plate cracks.

4. When continue to use graphite plate, the resistivity could be slowly appended to maintain long service life.

5. The service life will be shorter when the temperature moves up in the usage of graphite plates. The oxidation rate could increase after the furnace temperature arrives above 1800ºC. Please notice the surface temperature of graphite plates.
