Performance Application

The graphitized carbon electrode of our company use petroleum coke andcoal pitch as a binder agent made through calcining. burdening, kneading,pressing, roasting, graphitization and machining. It is a conductor which releases the electric energy to heat and melt materials in the form of electricarc in an electric arc furnace. The electrode we produce is a graphitized carbonelectrode, and is suitable for the mine furnace smelting production of silicon metal, iron alloy, etc.

Application Industry

The electrode is an ultra-high temperature conductive material which is mainly used in submerged arc furnaces to produce silicon metal, iron alloy, yellow phosphorus, calcium carbide and so on.

Since the 1980s, with the increasing scale of China's infrastructure construction,industries which use submerged arc furnaces to smelt yellow phosphorus, calciumcarbide, ferroalloys, industrial silicon have developed very fast. Especially after the 1990s, the development has become more rapidly. As the final heating treatment temperature of the conventional carbon electrode is about 1100 ° C,while the temperature of using submerged arc furnaces to smelt silicon, yellow phosphorus, calcium carbide, iron alloy and fused magnesium is 1800-2200 °C, when reaching the temperature range of 1600-2000 °C, the nitrogen, sulfur and othermetal impurities contained in the conventional carbon electrode escape in agaseous form, a serious "crystal rise" phenomenon will occur which will cause cracks inside the electrode. In severe cases, the block of the electrode may drop or break off during use which will affect the smelting production in the submerged arc furnace. However, this kind of phenomena can be avoided by the graphitized carbon electrode and it can effectively prevent cracks or falling off in the use process.
