Graphite electrode press device
Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking
(1) ordinary power graphite electrode, using graphite electrode with current density lower than 17A / cm 2, is mainly used in steel-making, smelting silicon, refining yellow phosphorus and other common power electric stove(2) anti oxidation coating graphite electrode. The surface is coated with an anti oxidation protective layer of graphite electrode to form a protective layer which has both conductive and high-temperature oxidation resistance, thus reducing the electrode consumption during steelmaking
Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
