The applications of graphite plate:
1. Refractory material: widely used in the metallurgical industry.
2. main graphite materials to machine graphite products
3. Conducting material: In the electronics industry, widely used for graphite electrode, brush, etc.
4. Sealing material: it can be as sealing ring in the equipment, such as centrifugal pump, hydraulic turbine, etc.
5. Anticorrosion material: Widely used in petroleum, chemical, hydrometallurgy departments.
6. Isolation, high temperature resistant, radiation protection materials
7. Molds: hot pressing molds, static casting molds, centrifugal casting molds, pressure casting
molds, fused refractory molds, etc.
8. Furnace parts: resistance heating elements, induction susceptors, structural elements and charging plates, furnace linings, heat shields and covers for pulling monocrystalline silicon or optical fibers, etc.
9. Anodes for the electrolysis of metals.
10. Parts for heat exchangers.
The precautions to extend the service life of graphite plate:
A. 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.
B. It’s much better to parallel the graphite plates rather than connect in series.
C. 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.
D. When continue to use graphite plate, the resistivity could be slowly appended to maintain long service life.
E. 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 1400℃. Please notice the surface temperature of graphite plates.
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?
