High Carbon Low Sulphur Graphite Carbon in Steel Casting

Semi-graphitized petroleum coke is widely used in industry. It is used in metallurgy, casting and precision casting as a carburizing agent. It is used to make high temperature crucible for smelting, lubricant for mechanical industry, making electrode and pencil lead; It is widely used in high-grade refractory materials and coatings in metallurgical industry, military industrial fire materials stabilizer, pencil lead in light industry, carbon brush in electrical industry, electrode in battery industry, catalyst in chemical fertilizer industry, etc. Graphitized petroleum coke is used in graphite, smelting and chemical industry according to its quality. Low sulfur, high quality cooked coke such as needle coke, mainly used in the manufacture of ultra-high power graphite electrodes and some special carbon products; Needle coke is an important material for developing new technology of electric furnace steelmaking in steelmaking industry. Medium sulfur, ordinary cooked coke, used in aluminum smelting. High sulfur, ordinary coke, is used for chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting fuel. Most of the petroleum coke produced in China is low-sulfur coke, which is used to make aluminum and graphite.

Graphite electrode is mainly made of high quality petroleum coke, needle coke as raw material, coal asphalt as binder, by calcination, batching, kneading, pressing, roasting, graptitization, machining and made, is in the arc furnace in the form of electric energy release electric energy to the furnace charge for heating and melting conductor, according to its quality index, can be divided into ordinary power, high power and ultra high power.
