Product description: This product is produced with ordinary grade petroleum coke. It has low graphitization temperature,Website:http://www.cnjingganrefractory.com, high resistivity, high expansion coefficient, poor thermal shock resistance and low permissible current density. 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:ItemRegular PowerΦ200-Φ300Φ350-600Resistivity μΩ•m ≤（Max）Electrode8.5Nipple6.5Bulk density g/cm3 ≥（min）Electrode1.531.52Nipple1.69Modulus of rupture Mpa ≥（min）Electrode8.57.0Nipple15.0Young’s modulus Gpa ≤（Max）Electrode9.3Nipple14.0Ash % ≤（Max）Electrode0.5Nipple0.5CTE(100-600℃) 100-6 /℃ ≤（Max）Electrode2.9Nipple2.8Additional note: 1) Small product size and specifications, high consumption rate per ton of steel 2) The products are used in ordinary power electric furnaces and other mining furnaces.
