Product Description

HP Graphite Electrode 500mm for Ladle Furnace​

 

Graphite electrode raw materials use the domestic petroleum coke and pitch coke and imported Japanese needle coke .HP grade graphite electrode contain 30% imported needle coke. UHP graphite electrode contain more than 80% imported needle coke. They are widely used in electric arc furnace(EAF), ladle furnace(LF) for the production of alloy steel, metal and nonmetallic materials. They are characterized by low resistance, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc

 

RP/HP/UHP graphite electrodes in diameter 100mm-600mm, we have a complete calcining, crushing, forming, baking, impregnation, graphitization, machining production lines and advanced technology and complete quality test equipment for quality control.
