Calcined Petroleum Coke The main uses of petroleum coke are pre-baked anode and anode paste used in electrolytic aluminum, carbon industry production of carbon additive, graphite electrode, smelting industry silicon and fuel. According to the different sulfur content, it can be divided into high sulfur coke (sulfur content more than 3%) and low sulfur coke (sulfur content less than 3%). Low sulfur coke can be used as anodic paste and prebaked anode for aluminum plant and graphite electrode for steel plant. The high quality low sulfur coke (sulfur content less than 0.5%) can be used to produce graphite electrode and carbonizer. Low-sulfur coke of general quality (less than 1.5% sulfur content) is often used to produce prebaked anodes. The low quality petroleum coke is mainly used in industrial silicon smelting and anode paste production. High-sulfur coke is commonly used as a fuel in cement factories and power plants.

The product application 1, graphitization petroleum coke is a very good smelting carburizer. 2, graphitized petroleum coke is the production of large cathode block, large carbon electrode, large graphitized electrode and high performance electrode paste raw material. 3, graphitization coke after deep processing can produce lithium ion battery anode materials, military industrial pyrotechnics material stabilizer, etc. 4, can also be used in the chemical industry reducing agent, casting reduction inoculated agent, refractory and other fields.

Graphite electrode is mainly made of petroleum coke and needle coke as raw materials, and coal asphalt as binder. It is made by calcination, batching, mixing, pressing, roasting, graphitization and machining. It is a conductor for heating and melting the charge in the form of electric arc in the electric arc furnace. It can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode. (1) For arc steelmaking furnace Electric furnace steelmaking is a major user of graphite electrodes. The output of eAF steel in China accounts for about 18% of the output of crude steel, and the graphite electrode used in steelmaking accounts for 70% ~ 80% of the total amount of graphite electrode. Electric furnace steelmaking is the use of graphite electrode into the furnace current, the use of electric extremes and charge between the arc generated by the high temperature heat source to smelting. Specification of high power graphite electrode: diameter 100mm-700mm, length 1500mm-2400mm

Graphite electrode mainly petroleum coke, needle coke as raw material, coal asphalt binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, according to its quality index, can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode. Graphite electrode production of the main raw material for petroleum coke, ordinary power graphite electrode can add a small amount of asphalt coke, petroleum coke and asphalt coke sulfur content can not exceed 0.5%. Needle coke is also needed to produce high - or ultra-high - power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and control sulfur content is not more than 1.5% ~ 2%, petroleum coke and asphalt coke should meet the relevant national quality standards.

(2) For mineral thermal electric furnace -arc furnace is mainly used in the production of industrial yellow phosphorus and silicon, etc., its characteristic is the lower part of the conductive electrode buried in furnace charge, arc formed within the material layer, and use the furnace charge itself from the resistance of the heat energy to heating furnace charge, one of the high current density required -arc furnace need graphite electrode, such as silicon 1 t per production to consumption of graphite electrode is about 100 kg, About 40kg of graphite electrode is needed to produce 1t yellow phosphorus. (3) For resistance furnace The graphitization furnace for the production of graphite products, the melting furnace for melting glass and the electric furnace for the production of silicon carbide belong to the resistance furnace. The material in the furnace is both the heating resistance and the heating object. Usually, the conductive graphite electrode is embedded in the furnace wall at the end of the resistance furnace, and the graphite electrode is used for the discontinuous consumption here. (4) For the preparation of special-shaped graphite products The blank graphite electrode is also used for processing various crucible, mold, boat and heating body and other special-shaped graphite products. For example, in the quartz glass industry, 10T of graphite electrode billet is needed for every 1T of electric fuse tube production; 100kg of graphite electrode billet is needed to produce 1t quartz brick Ordinary power graphite electrode specifications: diameter 75mm-1272mm, length 1500mm-2200mm
