High density Unmachined graphite block for Casting sand turning compression mold
The fine grain graphite block produced by cold molding are widely used in machinery, electronics, semiconductors, polycrystalline silicon, monocrystalline silicon, metallurgy, chemical, textile, electric furnaces, space technology and biological and chemical industries.
The graphite has the following characteristics:
1.Good electric conductivity and high thermal conductivity
2.Low thermal expansion and high resistance to thermal shock.
3.The strength increases at high temperature, and it can withstand over 3000 degrees.
4.Stable chemical property and hard to react
5.Self lubrication
6.Easy to process
Application
Graphite products Used for :
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.
