Customized carbon medium-grain graphite blocks of good heat resistance

Our medium-grain graphite materials have good resistance to thermal shock, oxidation and corrosion, and have suitable resistivity and homogenous structure. They can deal with the most demanding environments and have been used extensively in industries like solar, foundry, chemicals, electronics, ferrous metals, high-temp. processing, ceramics and refractory.

Product Description

The forming methods of graphite block include moulding, extrusion, vibration and isostatic pressure.

Our main and most preponderant graphite plate is vibratory compaction.

Our graphite block is made from the domestic high quality petroleum coke and needle coke, which is from China National Petroleum Corporation Daqing, Jinxi and Fushun petrochemical Company. So, we can guarantee the first-level quality.

Characteristics of graphite plate:

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.

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 ,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.
