1. Product Description:

Semi-graphitized petroleum coke is the product of calcined petroleum coke as raw material, which is placed in a graphitizing furnace, after high temperature graphitization, physical and chemical reaction and removal of sulfur and ash and other impurities. Sometimes called artificial graphite, used in carburizing agent, often known as ultra low sulfur/low carburizing agent.

An oily or dull gray hard solid petroleum product with a metallic luster and porosity, consisting of microscopic graphite crystals forming granular, columnar, or needle-like carbon bodies. Petroleum coke is a hydrocarbon, containing more than 99% carbon, but also contains nitrogen, chlorine, sulfur and heavy metal compounds.

2. Nature and use:

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.
