UHP600 EAF Graphite Electrodes Electric Arc Furnace Electrodes
UHP600 EAF Graphite Electrodes Electric Arc Furnace Electrodes
Introduction of EAF Graphite Electrodes
The EAF Graphite Electrodes is in electrically calcined anthracite, petroleum coke, graphite scrap, coal tar as main raw materials, carbon conductive material mixing, molding, sintering, mechanical processing, it is since twenty-first Century in a new energy saving and environmental protection materials in China gradually promote the use of, as the furnace with conductive electrode widely used in industrial silicon, iron alloy, calcium carbide, phosphorus and other metal or non metal smelting process. Carbon electrode is an energy saving and environmental friendly product.
