Needle Coke EAF Graphite Electrodes High Electrical Conductivity

UHP graphite electrodes always go along with following strength

* Low electrical resistance

* High electrical conductivity

* Strong chemical stability.

* High resistance to oxidation and thermal shock

* High machining accuracy, good surface finishing

Needle coke is a kind of high-quality coke with obvious fiber texture, particularly low thermal expansion coefficient and easy graphitization. Therefore, needle coke is a key raw material for manufacturing high-power or ultra-high-power graphite electrodes featured with low resistivity, small thermal expansion coefficient, and good thermal shock resistance.

Separated package---The electrodes and nipples are packaged separately.

Pre-connection package--- The nipples are connected with one end of electrode body in advance, and then both of them are packaged by wooden rafters, strapped with steel bands outside, the threaded nipples and end faces are covered by foamed plastic caps in order to protect them from damage.
