UHP Graphite Electrodes For Arc Furnace

UHP Graphite Electrodes For Arc Furnace

  【Introduction of Graphite Electrode】


       Using coal pitch as binder, the graphite electrode which is mainly made of petroleum coke and needle coke is being made through the process of calcination, compounding, kneading, pressing, baking, impregnation, graphitization and machining. It is a conductor that release electrical energy to heat and melt the charge in the form of an electric arc in an electric arc furnace, and has the characteristics of low electrical resistivity, good electrical conductivity, low ash content, uniform structure, good oxidation resistance and high mechanical strength.

【Application of Graphite Electrode】

    1. Used in electric arc steelmaking furnace Graphite electrode is mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. A strong current generates an arc discharge through the gas at the lower end of the electrode, and uses the heat generated by the arc to smelt.

    2. Used in ore-heating furnaces Graphite electrode ore-heating furnaces are mainly used to produce ferroalloys, pure silicon, yellow phosphorus, matte and calcium carbide, etc., which is characterized by electrical conductivity.

    3. For resistance furnaces, graphitization furnaces for producing graphite products, melting furnaces for melting glass, and electric furnaces for producing silicon carbide are all resistance furnaces.

    4. Used for processing a large number of graphite electrode blanks; also used for processing into various crucibles, graphite boats, hot die casting molds and heating elements for vacuum electric furnaces, etc...

【Using Guide for Rongxing Group Graphite Electrode】

    Being hard and brittle, artificial graphite electrode shall be specially handled. Proper operation may reduce the consumption and cost.

    A, Use special hoist tools to hoist graphite electrode. It is strictly forbidden to prize electrode ends up with crowbar. It must be handled with great care during transportation to avoid damage.

    B, Graphite electrode must be kept away from being moistened or wetted by rain, snow and water, and must be kept dry. It must be dried in the furnace before use. The drying temperature in  the furnace shall be less then 100℃.The drying period shall be not less than 48 hours.

    C, Not to be stored up near clay,slag etc.to avoid surface pollution and increasing resistivity. 

    D, Carefully checking before connection, make sure that the socked and nipple thread is not damaged, nipple pitch plug is in. Nipple screw shall not be damaged during lifting.

    E, Blow the nipple and socket threads with compressed air.

    F,Graphite electrode must be connected contacted closely and straightly.Use moment spanner for connecting electrode with suitable force.The gap between electrodes shall less than 0.4mm.

    G, The holding device must hold the electrode tightly,good contact and no arc.Otherwise,the connecting area will get red and oxidized and thin,leading breakage.

    H, Threaded portion of nipple socket shall not be damaged during hoisting by metal plug.Hoisting plug shall spin out and keep nipple socket clean.

    I, Lifting device of electrode must move stably when moving electrode.carefully check the  position of furnace cover after being repaired.To seal the cover with refractory to prevent up electrode from being oxidized by fire.

    J, The holding device of electrode shall hold the electrode beyond the socket area.
    For charging the furnace, the large scrap should be put at the bottom, the small one on the top, Charge material with low electric conductivity shall not been put on the top. In the course of melting, un-melted material shall be taken in time to avoid electrode breaking by falling material.
