Graphite electrode HP

Graphite electrode:

Main material is calcined coke and coal tar pitch as binders , via burdening, mixing, extruding, baking, (dipping), graphitizing, and machining to form. This product have the advantage of low specific resistance, high electric and thermal conductivity, excellent resistance to oxidation, high thermal shock resistance and mechanical strength, can be machined easier. Our graphite electrode products including RP, HP, and UHP. Widely apply into EAC smelting for alloy steel and other metallic or nonmetallic materials. We can also painting the electrode with wax, oil etc.as your required.
