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 used in high temperature vacuum furnace heating body, the highest temperature can reach 3000 ℃, is easy to be oxidized at high temperature, in addition to vacuum, can only be used in the neutral atmosphere and reducing atmosphere. Its smaller thermal expansion coefficient, thermal conductivity, resistivity (8 ~ 13) x 10-6 Ω m., good workability with SiC, MoSi2 rods, high temperature resistant, resistant to extreme cold hot sex good, price is cheap.
