  As an   HP Graphite Electrodes Manufacturer , share with you. Graphite as electrode: mainly use petroleum coke and needle coke as raw materials, coal tar pitch as binding agent, made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is an electric arc model in an electric arc furnace The form can release electric energy to control the structure of the furnace charge, heating and melting the conductor, according to its quality management index level, can be divided into a normal user power, high power and high power. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge can be classified into ordinary power, high power and ultra-high power a...

  Steelmaking process and how to avoid graphite electrode fracture? Let  Graphite Electrodes Exporter  bring you a look! The following solutions can be taken during the steelmaking process, which can effectively avoid electrode breaking and tripping: (1) The electrode phase sequence is correct and counterclockwise. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price Cheaper. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make h...
