  As a   Graphite Electrodes Manufacturer , share with you. Graphite electrodes are the main heating element used in electric arc furnaces, which is a steelmaking process that melts scrap from old cars or old home appliances to produce new steel. The construction cost of an electric arc furnace is cheaper than that of a traditional blast furnace, which is made of iron ore to make steel and is fueled by coking coal. However, steelmaking costs are higher because they use scrap steel and are driven by electricity. Graphite Electrodes The electrode is a part of the furnace cover and is assembled into a cylinder. Then, the current passes through the electrodes, forming a strong arc, melting the scrap. The size of the electrodes varies greatly, but the diameter can reach 0.75 meters (2 and a half feet), and the longest can reach 2.8 meters (9 feet). The largest weighs more than two metric tons. Up to 3 kilograms (6.6 pounds) of graphite electrodes are required to produce one ton of ...

  As a   Graphite Electrodes Solutions Supplier , share with you. Graphite has excellent thermal conductivity, 700-1300 watts/(MK) thermal conductivity (corresponding to 2 to 3 times copper, thermal conductivity of metal materials such as copper and aluminum far exceed), the weight is more than copper and aluminum Light, with a density of 0.85-1.9 g/cm3 (corresponding to 1/4 to the density of copper, 1/10 of the density of aluminum, 1/1.3 to 1/3), and has a better processing natural graphite material than aluminum It is made of copper material with high thermal, chemical and physical stability and high conductivity. Excellent heat dissipation is the material used for radiators. Graphite Electrodes Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in neutral or reducing atmospheres. Its thermal expans...
