RP graphite electrodes
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. (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. (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
