UHP Graphite Electrode for Arc Furnaces is made up of high quality need coke. As a kind of conductor, it releases electrical energy in the form of an arc in an electric arc furnace to heat and melt the charging materials.What's more, it has the advantages of good electrical conductivity, low ash content, compact and uniform structure, good oxidation resistance and high cost effective. It is widely used in electric arc furnaces, refining furnaces, steel plants, silicon plants and so on.
