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
