HP Graphite Electrode for Ladle Furnace Supplier
silicon, phosphorus smelting industry. We can provide various grades (UHP graphite electrodes, HP graphite electrodes, SHP graphite electrodes, RP graphite electrodes) and specifications of the graphite electrodes, products with a low resistance, high physical density, oxidation resistance, and high precision machining to meet the needs of different users.
Our graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm.
Programmable properties
-Good electrical conductivity
-High resistance to thermal shock
-High mechanical strength
