Introduction to some categories of graphite electrode

The graphite electrode 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 plus appropriate adhesives, 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 electrical conductivity, and is not easy to break. It is suitable for cutting metal into a shape that meets the requirements.

The graphite electrode is often used as an electric heating element in a high-temperature vacuum furnace. 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, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, graphite The raw material price is relatively cheap.
