High Carbon Graphite Electrode Rod For Industrial Use
Graphite rod is a non-metallic product. As a necessary cutting consumable before welding in the carbon arc gouging cutting process, it is made of carbon and graphite with appropriate binders, formed by extrusion, and baked at 2200℃. It is made by plating a layer of copper after the section. It has high temperature resistance, good conductivity, and is not easy to break. It is suitable for cutting metal into a shape that meets the requirements.
Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, the resistivity is (8~13)×10-6 Ω·m
