UHP Graphite Electrode

Product description: The product is made of high-grade needle coke.The graphitization heat treatment temperature is as high as 2800-3000?. The resistivity of the product is lower,Website:http://www.cnjingganrefractory.com, such as <5.5µO•m. It allows higher current density, smaller expansion coefficient and excellent thermal shock resistance. The graphite electrode products we supply are used in roughing furnace and refining furnaces. They have three quality grades: RP, HP and UHP. They are divided into various specifications according to their diameters and lengths. It is a good conductive and heat conductive high temperature product for steelmaking.  The product we supply has a low consumption rate per ton of steel.in roughing furnace, the consumption rate of UHP product per ton steel is less than 1.8kg, and in refining furnace, the consumption rate of UHP product per ton steel is less than 0.5kg.  The product is black and cylindrical.Index:ItemUitra high PowerF250-F400F450-600Resistivity  µO•m =(Max)Electrode5.5Nipple4.5Bulk density  g/cm3 =(min)Electrode1.671.66Nipple1.75Modulus of rupture  Mpa =(min)Electrode11.0Nipple20.0Young’s modulus  Gpa =(Max)Electrode14.0Nipple18.0Ash   % =(Max)Electrode0.3Nipple0.3CTE(100-600?) 100-6 /? =(Max)Electrode1.5Nipple1.4Additional note: 1)Product specifications are F 400-700 mm 2)The product is used in UHP electric furnace, and the Consumption rate per ton of steel is lower.
