The forming methods of graphite bricks include moulding, extrusion, vibration and isostatic pressure.
Characteristics of graphite bricks:
1.Low electric resistance,
2.Good electric and thermal conductivity,
3.High oxidation resistance,
4.Greater resistance to thermal and mechanical shock,
5.High mechanical strength,
6.High machining accuracy and so on.
1. Refractory material:
Widely used in the metallurgical industry.
2. Conducting material:
In the electronics industry, widely used for graphite electrode, brush,, etc
3. Wear-resisting material and lubricant:
Use graphite as wear-resisting and lubrication materials, can be 100m/s speed sliding in - 200 ~ 2000 °C temperature range, no or less lubricanting oil.
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. Protection materials:
Insulation, high temperature resistant, radiation
7. Furnace parts:
resistance heating elements, induction susceptor, structural elements and charging plates, furnace linings, heat shields and covers for pulling monocrystalline silicon or optical fibers, etc.
8. Anodes for the electrolysis of metals.
9. Parts for heat exchangers.
