Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, with coal tar pitch as the binder. They are produced through calcination, batching, kneading, forming, baking, impregnation, graphitization, and machining. They are conductors that release energy in the form of an electric arc in an electric arc furnace to heat and melt the furnace charge. They are mainly used in steelmaking production, and in submerged arc furnaces for metal silicon and yellow phosphorus production, etc. According to its quality indicators, it can be classified intoregular power grade, high-power grade and ultra-high-power grade. The holding parent company, Lanzhou Jinkaize Industry and Trade Co., LTD., as an authorized sales subsidiary of Shanxi Sinsage Carbon Materials Technology Co., LTD. (formerly Shanxi Ximu Donghai Carbon Co., LTD.), a domestic high-quality graphite electrode manufacturer, is responsible for the sales business of graphite electrodes. The annual production capacity is 40,000 tons.
