Graphite electrodes are widely used, mainly used in electric furnace steelmaking, submerged thermal electric furnaces, resistance furnaces, etc.1. Graphite electrodes are used in electric arc steelmaking furnacesThe main user is electric furnace steelmaking. Electric furnace steelmaking uses graphit Read More
IntroductionGraphite electrodes are mainly made of petroleum coke and needle coke as raw materials, and coal tar pitch as binder. They are made by calcining, batching, kneading, pressing, roasting, graphitization and machining. Electric energy is released in the form of electric arc in an electric a Read More
What is Quenching? Quenching of steel is a heat treatment process in which the steel is heated to the critical temperature Ac3(hypo-eutectoid steel) or Ac1(hypereutectoid steel), holding it for a period of time to make it austenitized in whole or part, and then rapidly cooling to below MS( or isothe Read More
Graphite electrodes are mainly divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes. Graphite electrode manufacturers will introduce their respective characteristics and precautions.Ordinary power graphite electrodeThe current densi Read More
