In the production of the national economy, the application of graphite rods is particularly extensive. Now, Henan Liugong Graphite Co., Ltd. will introduce to you the specific meanings of graphite rods, high-purity graphite rods, and high-temperature resistant and high-purity graphite rods:
Graphite rod is a non-metallic product. As a kind of cutting consumables before welding in the carbon arc gouging cutting process, it is made of carbon, graphite and appropriate binders, and is formed by extrusion, baked at 2200 ° C and then plated Made of a layer of copper, high temperature resistance, good electrical conductivity, not easy to break, suitable for cutting metal into required shapes.
Graphite rods are often used in the electric heating body of high temperature vacuum furnaces. The operating temperature can reach 3000 ° C. It is easy to be oxidized at high temperatures. Except for vacuum, it can only be used in neutral atmosphere or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, and its resistivity is (8~13) × 10-6?Ω·m.
Henan Liugong Graphite Co., Ltd. specializes in the production of small-sized high-purity graphite rods, and high-strength graphite rods are machined.
