Graphite Electrode

Graphite Electrode

Short Description:

Description: Graphite electrode mainly with petroleum coke and needle coke as raw material and coal tar as binder, it is made by calcining, batching, kneading, kneading, pressing, baking, graphitization and machining. It is a conductor that releases electric energy to furnace material in the form of arc in electric arc furnace, and can be divided into ordinary power, high power and high power according to its high quality index. Usage :    (1) For arc furnace (2) For ore thermal furnace (3) F...
