high power graphite rods for electrode

  high power graphite electrodes For electric arc furnace Graphite electrode is mainly used in EAF steelmaking. Electric furnace steelmaking is the use of graphite electrode into the current furnace, powerful current arc discharge is generated in the bottom electrode by gas, produced by arc heat to smelting. According to the electric capacity, equipped with a graphite electrode with different diameters, in order to make the electrode in continuous use between electrodes, electrode thread joint. Steelmaking with graphite electrode for the total amount of graphite electrode in 70 ~ 80%. For ore heat furnace Graphite electrode submerged arc furnace is mainly used in the production of iron alloy, pure silicon, phosphorus, copper and calcium carbide, which is characterized by the lower conductive electrode buried in the burden, so in addition to the arc between the plate and the burden of generating heat, the current through the charge by charge resistance can also produce heat. Silicon consumed per ton of graphite electrode of about 150kg per ton of yellow phosphorus, consumes about 40kg graphite electrode. For resistance furnace Graphitization furnace, melting glass production of graphite products with the furnace and the production of silicon carbide electric stove are resistance furnace, the material is loaded in the furnace heating resistor, it is heated object. Usually, the graphite electrode conductive insert furnace head wall bed end, so the conductive electrode is not continuous consumption. In addition, a graphite electrode blank is also used for processing various crucible, Shi Mozhou ware, casting and vacuum electric furnace heating hot body shaped products. As in the quartz glass industry, the production of LT electric melting pipe with graphite electrode blank 10t, the production of LT quartz bricks of consumable electrode blank 100kg.
