The graphite electrode has a cylindrical shape. They are obtained by sintering a mixture of bituminous coke, thermal penicillin, coke, grapitization waste, coal tar pitch and coal tar, and then grapitization for 100 hours or more at 2,700-2,900℃, after which they acquire different properties necessary for different electrodes. We are graphite electrode manufacturers, production experience, strong technical force, welcome to consult and purchase.
The graphite electrode design consists of two working parts made of graphite with an insulating washer between them. The gasket consists of iron oxide, aluminum, copper and cryolite particles. It also contains magnesium or other metals that are chemically more active than iron instead.
Graphite electrode manufacturers. The synthetic graphite used to make products is a carbon modifier derived from coal pitch and petroleum coke. After proper treatment, the material becomes heat- resistant. Graphite melts at a temperature of about 3500℃, so it is optimal for producing non- melting electrodes. Depending on the diameter, the thread shape of the graphite product varies: for the d electrode, from 75 to 200mm, the thread is cylindrical and more than 250mm is conical.
It has good conductivity and less loss in operation. Even at high temperatures in the air, the material does not oxidize and can be used for a long time. High purity, high chemical resistance, low resistance, even at high current density, the graphite material shows good durability.
We are a professional graphite electrode manufacturers with rich experience. With many years of manufacturing experience, strong technical force, complete product categories, sincerely welcome all users to come to our factory to visit and purchase, we will serve you wholeheartedly.
