PRODUCTION SPECIFICATION
HP graphite electrode 400mm
Type: We can supply High purity graphite electrode.Regular power, high power and ultra-high power graphite electrode can be supplied.Fine grained structral graphite electrode and oxidation resistant coating graphite electrode are provided.Any size could be requested by the customer.
Application:Mainly used for the electric arc furnace to smelt the molten steel and used for the refining furnace such as AOD VOD LF furnaces in the steel and non-ferrous metal metallurgy industry.
Advantage:Graphite electrode is more and more widely used in the iron and steel industry.It makes less pollution and saves more power,it's good for our environment.The graphite electrode has long working-life,as it needn't to be changed often,that reduce the labor indensity of the works and avoid much danger.
