* Low thermal expansion coefficient
* Low ash,Its ash content is controlled within 3%.
* Dense and equal structure,Low graphite electrode consumption.
* Good oxidation resistance
* High mechanical strength
* Needle coke content accounts for 80%, raw materials imported from Japan and South Korea

Product Process

1.Raw Material

Use of high-quality calcined petroleum coke production materials

2. Crushing & Screening

They are broken needle coke in mechanical equipment and screening according to the formula after the proportion of the ingredients.

3. kneading

Ingredients of the raw materials with a certain proportion of asphalt heated kneading, made with plastic paste.

4. Forming

After kneading of the paste by temperature cooled to process, and forming into the compressor according to the requirements of product specifications

5. Baking

Within the roasting road, will be a “green” electrode roasting to the specified temperature, according to the requirements of the process. After roasting products with special dipping, density, and mechanical strength, improve product performance in order to improve the products and then repeat the roasting of impregnated products.

6. Graphitization

Second, after roasting the products within the graphitization resistance furnace power up to 3000 ℃, the carbon atoms rearrange into specific crystalline form structure, carbon into graphite.
