Zhen'an Graphite Electrode Production
Graphite electrodes are made of low-ash raw materials such as high-quality petroleum coke, imported needle coke, and high-quality coal tar pitch. They are made into graphitized semi-finished products through calcination, batching, kneading, molding, multiple roasting and impregnation, and graphitization. Finally, they are finely processed by professional CNC lathes. The products have the advantages of low resistivity, low ash content, uniform structure, good thermal vibration resistance, high mechanical strength, low thermal expansion coefficient, and precise matching of electrodes and joints. They are excellent materials for electric furnace steelmaking and ore-heat furnace smelting.
