Product Details

ultra high power graphite electrode uhp for arc furnaces with factory price

 

  1. Product detail

    Graphite electrode raw materials use the domestic petroleum coke and pitch coke. HP grade graphite electrode add 30% imported needle coke. UHP graphite electrode use more than 80% imported needle coke. They are widely used in electric arc furnace, ladle furnace for the production of alloy steel,metal and nonmetallic materials. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc
