Characteristics of High Temperature Resistant Graphite Rod
High temperature resistant graphite rod is commonly used as the electric heater of high temperature vacuum furnace. The maximum service temperature can reach 3000 ℃, and it is easy to oxidize at high temperature.
In addition to vacuum, high temperature resistant graphite rods can only be used in a neutral or reducing atmosphere. The thermal expansion coefficient of high temperature resistant graphite rod is small, the thermal conductivity is large, and the resistance coefficient is (8 ~ 13) × 10-6 Ω·m. High temperature resistant graphite rod has good cold and heat resistance and low price.
Application of High Temperature Resistant Graphite Rod
High temperature resistant graphite rod is often used in the metallurgy and machinery industry. It is mostly used as an electric heater of a high-temperature vacuum furnace, and the maximum service temperature can reach 3000 ℃. Because graphite rod has the property of high-temperature resistance, it can be called a protective agent when it is used in steelmaking. It is the lining of people's metallurgy.
In the machinery industry, we usually use graphite rods as a lubricant because they can slide quickly at higher temperatures. As a high-temperature metallurgical material, the graphite composite rod is made of graphite, carbon, and appropriate adhesive. Therefore, this change in high-temperature resistance can be used as a mold for glassware, making the size of the manufactured castings more accurate, which can also save more metal materials.
