Graphite electrode and nipples, Graphite electrodes cost
The production cost of graphite electrode is mainly raw materials and electricity, Graphite electrode cost of raw materials accounted for about 67%.

Graphite electrode and nipples

Graphite electrodes are made of petroleum coke, needle coke, etc. as raw materials, coal tar pitch, etc. as binders, through raw material crushing, batching, mixing, compression molding, roasting, impregnation, secondary roasting, graphitization, machining, quality inspection, It is prepared in 11 processes including packing and leaving the factory, with many production processes.
Graphite electrodes structure drawing, It's composed of body and nipple.
Graphite electrodes structure drawing, It's composed of body and nipple.
The production cycle of ordinary graphite electrodes is as long as 50 days, and the ultra-high power needs at least 65 days. Graphite electrode nipple require two times of impregnation and three times of firing, and the production cycle is longer.

Graphite electrodes cost

Graphite electrode cost is greatly influenced by the price of raw materials.
Calculation method of cost per ton of graphite electrode:
Calculation method of cost per ton of graphite electrode
CPC--unit price per ton of petroleum coke
CNC--unit price per ton of needle coke
CCT--unit price per ton of coal pitch
