Graphite electrode production process

1) Calcination
During the calcinating process, the physical and chemical properties of raw materials are increased.
2) Forming
Kneaded material is formed using an extrusion press.  
3) Baking
Through the baking process, the thermal stability, mechanical strength and electrical conductivity of materials can be greatly improved.
4) Impregnation
The baked electrodes are impregnated with a special pitch to give them the higher density, mechanical strength, and electrical conductivity to withstand the severe operating conditions inside the furnaces.
5) Graphitization
Processing the baked material at extremely high temperatures to change its structure from amorphous carbon to graphite and obtain excellent material properties.
6) Machining
Machining the graphitized material to achieve the required size, shape and accuracy, to make the electrode body and pin according to the specification of customers.
