Carbon and graphite products
A、Graphite electrode is mainly made of petroleum coke and needle coke as raw materials, using calcination, proportion, kneading, pressing, roasting, graphitization, mechanical processing and other binder.They are conductors that release electrical energy in the form of electric arcs to heat and melt furnace materials.According to its quality index can be divided into ordinary power, high power and ultra high power.Graphite electrodes include:
(1) General power graphite electrode.The graphite electrode with current density less than 17A/cm 2 can be used in ordinary electric furnace such as steelmaking, ironmaking and smelting.
(2) Oxidation resistant coated graphite electrode.The graphite electrode, coated with an oxidation protection, forms a conductive layer that conducts electricity and resists high-temperature oxidation, reducing the cost of the electrode during steelmaking.
(3) High-power graphite electrode.Graphite electrodes with allowable current density of 2 / cm are mainly used in high-power electric arc furnaces for steelmaking.
(4) Ultra-high power graphite electrode.Graphite electrodes with current densities greater than 25A/cm 2 are allowed.Mainly used in ultra-high power electric arc furnace for steelmaking.
