~The graphite electrode is made of high-quality petroleum coke,
needle coke, coal pitch and other raw materials through
calcination, intermediate crushing, screening, dosing, mixing,
compression, roasting, high pressuer impregnation, graphitization,
machining and other processes, has compact and even structure, good
electric conduction and heat-conducting properties, high mechanical
strength and strong oxidizatin corrosion resistance at high
temperature, is widely usded for arc furnaces and submerged arc
furnace to smelt various alloy steel, yellow phosphorus, industry
silicon, brown aluminum oxide and other alloy and nonmetal
materials.
