The components of the graphite electrode are mainly petroleum coke, needle coke, coal pitch, which are produced by calcination, compounding, kneading, pressing, roasting, graphitization and machining. The electric energy is released in the form of an electric arc in the electric arc furnace. Heat the melted conductor. Graphite electrodes are used in steelmaking electric arc furnaces and refining furnaces as conductive electrodes. It is used as a conductive electrode for industrial silicon furnaces, yellow phosphorus furnaces, corundum furnaces, and the like. The performance of graphite electrode mainly includes: good electrical conductivity, strong thermal shock resistance and high mechanical strength.
     1. According to the capacity of the electric furnace and the load of the transformer, the grade and diameter of the electrode are appropriately selected.
     2. When charging the electric furnace, the bulk material should be installed at the bottom of the furnace to prevent the furnace material from collapsing and breaking the electrode. In the smelting process, lime and other non-conducting should be avoided.

     3, the object is concentrated in the bottom of the electrode, otherwise it will affect the electrode energization, and even lead to the electrode breakage and other matters needing attention.
