Product Description Product DescriptionGraphite recarburizers generally come from two ways, one is the waste cutting of graphite electrodes, and the other is the graphitized product of petroleum coke 3000 degrees.Carburizer can be used during casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or use no pig iron. Most of the recarburizers are suitable for electric furnace melting, and a small number of recarburizers with particularly fast absorption rate are used in cupolas. The charging method of electric furnace smelting should be to put the carburizing agent together with the scrap materials such as scrap steel. The small amount of addition can be added to the surface of the molten iron. However, it is necessary to avoid feeding large quantities into the molten iron, in order to prevent too much oxidation and the situation that the carbon increase effect is not obvious and the carbon content of the casting is insufficient. The amount of recarburizer is determined according to the proportion of other raw materials and the carbon content. Different types of cast iron, choose different types of carburizing agents according to needs. The characteristics of the recarburizer itself select pure carbon-containing graphitized substances to reduce excessive impurities in pig iron. The proper choice of recarburizer can reduce the production cost of castings.Detailed PhotosProduct Parameters itemvaluePlace of OriginChina HebeiTypeFoundry CokeCalory (J)7200Sulphur Content (%)0.5Ash Content (%)8Fixed Carbon (%)90Moisture (%)0.45Phosphorus Content (%)0.03Volatile Matter (%)1.37Abrasive ResistanceM10<5%Crushing StrengthM40>90%Brand NameNalaiModel Number Nl81CertificateRoHS, ISO, CESpecific Area0.6-0.8m2/GOther nameGraphitized Petroleum CokeColorBlackUsageBlast Furnace IronmakingIgnition temperature (in air) is450-650Bulk Density400-500kg/ M3Apparent Density0.88-1.08g/ Cm3True Density1.8-1.95g/cm3CertificationsPackaging & ShippingCompany ProfileShijiazhuang Nalai Biotechnology Co., Ltd Provide high quality Graphite electrode, Graphite electrode mainly petroleumcoke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization,machining, made of, can be divided into ordinary power, high power and high power, mainly used in steel smelting electric arc furnace and refining furnace smelting furnace, electric furnace steelmaking is the use of graphite electrode in furnace to importhe current, strong current in the lower electrode by gas arc discharge, use the heat generated by the arc for smelting.Graphite electrodes of different diameters are used according to the capacity of the electric furnace. For continuous use of the electrodes, the electrodes are connected by the threaded joint of the electrodes. The graphite electrode used in steelmaking accounts for about 70 ~ 80% of the total graphite electrode consumptionIf you need, please feel free to contact us.
