Product introduction:
Our graphite blocks, made from excellent petroleum coke, are widely used in metallurgy, machinery, electronics and chemical industry, etc.
Various graphite blocks with qualified materials are available in our factory.
We could supply fine-grain graphite, medium-grain graphite, high pure graphite, isostatic graphite, kinds of domestic and imported graphite, and so on.
Typical sizes as follows: 400x400x1800; 500x500x1950, 500x330x1950, 500x430x1950, 520x350x2150, 630x630x2200, 600x500x2200, 820x340x2100, 520x350x2600, 1100x11000x350, etc.
Application:
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.
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.
The characteristics of our graphite blocks:
1. low electric resistance
2. high temperature resistance
3. good electric and thermal conductivity
4. high oxidation resistance
5. greater resistance to thermal and mechanical shock
6. high mechanical strength and machining accuracy
7. homogeneous structure
8. hard surface and good flexural strength
The forming process of our graphite blocks:
Our graphite block is made from superior petroleum coke, and manufactured through crushing, calcining, medium crushing, milling, screening, dosing, kneading, forming, baking, impregnation, graphitization, machining, and inspection. Every step procedure is strictly controlled by our engineers to ensure the product quality.
