Product Description

Product Name: High quality UHP graphite electrode
Product features: Ultra-high power graphite electrode is mainly made of petroleum coke and needle coke. Coal bitumen is used as binder, which is made by calcination, compounding, kneading, pressing, roasting, graphitization and machining. In the electric arc furnace steelmaking, electric energy is released as an electric arc as a conductor to heat and melt the charge. According to the high quality of the graphite electrode quality indicators, it can be divided into ordinary power, high power and ultra high power.

Technology and Innovation

In order to maintain our technological leadership and meet the technical requirements of the different types of furnaces( AC/DC, Ladle furnaces), we constantly invest in our production technologies. We have successfully produced large size UHP graphite electrodes with diameters from Dia.600 mm to Dia.700 MM, which filled gap in this field in domestic markets. With the characters of cost savings and good stable performances, our large size UHP graphite electrodes have replaced imported graphite electrodes in domestic market and accepted by overseas famous iron & steel plants gradually.
