2017 11/10

A, raw material
The graphite electrode is made of high quality and high quality.
2. Broken and sieving
The needle coke is broken in the mechanical equipment and after sieving, according to the formula requirements proportion.
Three, kneading,
The ingredients are mixed with a certain proportion of asphalt to make a plastic paste.
Four, pressed
After mixing, the paste is cooled to the process temperature, and the press is pressed to the press according to the specifications.
Five, the roasting
Born in baking furnace, the "embryo" electrode according to the process requirement of roasting to the specified temperature, roasting products using special impregnating pitch, after dipping, according to specific process to improve the density, mechanical strength, and then to repeat the roasting of impregnated products, to enhance the product performance.
Vi. Graphitization

To the roasting of secondary products within the graphitization resistance furnace power up to 3000 ℃, the carbon atoms rearrange a specific crystalline form structure, carbon into graphite.
