Usage:
Graphite electrode is a conductive material for smelting iron and steel, brown corundum, metal
silicon and so on in electric furnace. Circuit steelmaking.
HP graphite electrode is mainly used for ultra-high power electric arc furnaces with the current
density range of 18-25A/cm2.
Features :
Anti-oxidation treatment for longevity.
High-purity,high-density,strong chemical stability.
High machining accuracy,good surface finishing.
High mechanical strength,low electrical resistance.
Resistant to cracking & spalling.
High resistance to oxidation and thermal shock.
