Graphite electrode is a high temperature resistant graphite conductive material made of petroleum coke and needle coke as the main raw materials and coal tar as the binder, through a series of processes such as calcination, crushing and grinding, mixing and kneading, extrusion molding, roasting, pitch impregnation, graphitization, and mechanical processing. Calcined petroleum coke is a product formed by calcining petroleum coke at a high temperature of 1300 degrees without contact with oxygen. Graphitized petroleum coke recarburizer has the characteristics of high purity, high fixed carbon content, low sulfur and low nitrogen, making it an indispensable recarburizer in the metallurgical industry.
