Product Description

Product Description Steel Casting UHP Extruded Carbon Graphite Electrode with Nipples 
 

Graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading,molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, with low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
There are three grades including RP graphite electrode,HP graphite electrode and UHP graphite electrode.
