• Graphite electrode for electric arc furnace

    The graphite electrode of the electric arc furnace refers to the conductor material that the electric arc furnace releases electric energy in the form of an electric arc to heat and melt the charge. It mainly uses petroleum coke and needle coke as raw materials, and coal tar pitch is used as a binder. It is calcined, batched, kneaded, and pressed. , Roasting, graphitization, and machining. According to its quality indicators, it can be divided into regular power graphite electrodes, high power graphite electrodes, and ultra-high power graphite electrodes. The steel-making electric arc furnace uses graphite electrodes as conductive materials and transfers heat energy to the charge through arc discharge to melt the charge. An ordinary electric arc furnace has three electrodes, each of which consists of 3 to 4 electrodes connected together with a tapered joint. The electrode is clamped by the gripper at the end of the cantilever. The cantilever and the soft bus connected to the power…

  • Three important steps of electric arc furnace steelmaking

    What is an electric arc furnace? Industrial furnaces that produce electric arc heating through metal electrodes or non-metal electrodes are called electric arc furnaces. Electric arc furnace (EAF) is an electric furnace that uses electrode arcs to produce high temperatures to smelt ores and metals. Electric arc steelmaking furnace uses electric energy as the main energy source. The electric energy is arc drawn through the discharge of graphite electrodes and the charge to generate high temperatures above 2000 ~ 6000 ℃, and the scrap steel raw materials are melted by means of arc radiation, temperature convection, and heat conduction. Electric arc furnace steelmaking is highly adaptable to the charge. It uses scrap steel as the main raw material, but it can also use molten iron (blast furnace or hot metal), sponge iron (DRI) or hot briquette (HBI), pig iron and other solid And liquid iron-containing raw materials. The development of an electric arc furnace After the middle of the 19th…
