Graphite electrodes are used in electric furnace steelmaking and ore-thermal electric furnaces to smelt alloy steel, brown corundum and other alloys and non-metals. During the EAF steelmaking process, current is introduced through the graphite electrode to generate an arc in the smelting area, and smelting begins when the temperature reaches about 2000 degrees Celsius.

Graphite Electrode Manufacturing Process
The graphite electrode manufacturing process mainly includes the steps of raw material preparation, mixing, molding, roasting, impregnation and graphitization. details as follows:
Raw material preparation: Select petroleum coke, needle coke, asphalt and other binders and mix them according to a certain proportion.
Molding: The mixed material is extruded to form a cylindrical electrode blank.
Roasting: The blank is roasted at high temperature to fully carbonize it.
Impregnation: The roasted blank is placed in an impregnation tank for full impregnation treatment to improve the conductivity of the electrode.
Graphitization: Through high-temperature treatment with electricity, the carbon atoms are rearranged and the graphitization process is completed.
