 1. Company Introduction 

We supply GRAPHITE ELECTRODEs of reasonable price and high quality and are especially expert at producing UHP Grade Carbon GRAPHITE ELECTRODEs and HP GRAPHITE ELECTRODEs for EAF and LF. Our hot sale GRAPHITE ELECTRODEs are with high bulk density, low specific electrical resistivity, low specific consumption and a high content of needle coke.

Our GRAPHITE ELECTRODEs on sale have successfully completed the certification for ISO9001:2000 quality system, ISO 14001:2004 environment system and GB/T28001:2001 safety system. In addition to this, certifications have been given for BV, SGS and Asia Inspection.

We offer carbon GEs to steel mills in Italy, South Africa, Chile, South Korea, Viet Nam and Romania since 2010.

Our GRAPHITE ELECTRODEs are made from high-quality petroleum coke, needle coke and coal pitch. Featuring with low resistivity, good electrical conductivity, low ash, compact structure, good anti-oxidation and high mechanical strength and high precision machining, our products serve as the best conductive material for electric arc furnaces and smelting furnaces.

Our products are widely used in electric arc furnaces and ladle refining furnaces for steelmaking, electric smelting furnace for producing ferroalloy, pure silicon and yellow phosphorus, electrical resistance furnaces for glass melting, silicon carbide making, graphite product manufacturing.

Having an outstanding sales team, we offer first-rate service and technical support in an effective manner. We'd like to establish a good business relationship with companies from home and abroad with all sincerity.
