Product Description

Product Description

Graphite Electrode with Nipple

Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace,ladle furnace, submerged arc electric furnace for theproduction of alloy steel, metal and nonmetallic materials. 

Our graphite electrodes include regular power, high power, super high power and ultra high power. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, ect. 
 

Our plant offers various dimensions and grades to meet customers' requirements for the specific applications.

Graphite electrode refers to a kind of resistant electrode made of petroleum coke and pitch coke as aggregates and coal pitch as binder. It is made by calcining raw materials, crushing and grinding, batching, kneading, shaping, roasting, impregnation, graphitization and mechanical processing. High temperature graphite conductive material. It can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
