Description

RP HP UHP graphite electrode rod

 

Graphite rod for non-metallic products, as a necessary in the process of carbon arc air gouging cutting cutting in front of the welding consumables, is made of carbon, graphite, and the proper adhesive, by extrusion forming, after 2200 ℃ baking spin segments is made by a layer of copper plating, high temperature resistance, good electrical conductivity, not easy to break, suitable for metal cutting into the shape of a meets the requirements.

Graphite rod is often used in high temperature vacuum furnace heating body, the highest use temperature up to 3000℃, easy to oxidize at high temperature, in addition to vacuum, can only be used in neutral atmosphere or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13) ×10-6 ω ·m, better processing than SiC, MoSi2 bar, high temperature resistance, cold and hot resistance is good, the price is cheaper.
