Carbon electrode production line

　　Carbon electrodes are generally used in calcium carbide and industrial silicon smelting. Due to their large diameter and high current density, large-sized carbon electrodes are gradually shifting to using low-ash, low-sulfur petroleum coke as raw material to produce large-sized graphite electrodes for industrial silicon and calcium carbide smelting.

　　Carbon electrodes are conductive carbon materials made from raw materials such as electro-calcined smokeless coal, petroleum coke, graphite fragments, and coal pitch, through processes of mixing, molding, baking, and machining. They are a new type of energy-saving and environmentally friendly material, widely used in the smelting of metals or non-metals such as industrial silicon, ferroalloys, calcium carbide, and yellow phosphorus. Carbon electrodes are energy-saving and environmentally friendly products. Their use in calcium carbide and ferroalloy electric furnaces can significantly reduce smelting power consumption and pollution.
　　Currently, they have begun to replace the more expensive graphite electrodes in industrial silicon and yellow phosphorus smelting furnaces. In submerged arc furnaces of the same capacity, compared with graphite electrodes, carbon electrodes can be made with a larger diameter (currently, China can produce carbon electrodes with a diameter of Φ650-Φ1272mm, while graphite electrodes can reach Φ1146mm), widening the arc zone in the furnace, stabilizing the arc, ensuring thermal melting efficiency, increasing product output, and reducing power consumption.
