Graphite Electrodes Manufacturing (Production) Process | Graphite & Carbon |


1. Raw materials (100% imported needle coke, coal tar pitch).
a) Crushing.
b) Calcining (Calcination).
c) Pulverizing, Weighting, Screening and Dosing (Classify the screened coke according to gain size and store them in individual silos).
d) Mixing (Knead the mixed coke and binder pitch into kneader).
2. Forming (The kneaded material is formed into green electrode by extrusion press through various press nozzles and by the extrusion press and cut into specified lengths).
a) Water-cooling
3. Baking (1200 °С, 40-60 days)
4. Impregnation
5. Rebaking
6. Graphitizing – 10 days. 2800 до 3000 °С.
7. Machining
8. Inspection
9. Packing
10. Shipping
