Calcining
High quality needle coke or petroleum coke is broken into particle size meeting process requirements by mechanical equipment after self calcination
01
Crushing Screcning Burdening Kneading
Needle coke is broken in mechanical equipment, and after screening, it is proportioned according to the proportion required by the formula. The screened raw material particles are mixed with a certain proportion of asphalt according to the formula requirements, and heated and stirred to form a paste with certain plasticity
02
Forming
The paste with suitable temperature is added to the molding machine, pressed and extruded, and formed into green green body according to the specification
03
Baking for the first time
The graphtie electrode is roasted to a certain temperature in the roasting furnace according to the process requirements
04
Impregnation
The roasted graphite electrode is treated with special asphalt and vacuum high pressure to make the product more compact
05
Baking for the second time
After the impregnation, the products are fired in the tunnel kiln for the second time to fully coke the asphalt and improve the density and strength of the products
06
Graphitization
After the impregnation, the products are fired in the tunnel kiln for the second time to fully coke the asphalt and improve the density and strength of the products
07
Machining
The graphitized products are machined into finished products that meet the dimensional accuracy requirements

Quality Control

The processed products need to be tested for various physical and chemical performance indicators and processing accuracy before they can be packed.
The packing is packed in wooden cages, the joints are packed in wooden cases, or the electrodes and joints are packed together according to the user's requirements, lined with waterproof and dustproof plastic cloth, and the external steel belt is fixed, beautiful and firm, which is suitable for land and sea transportation
