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.
