Graphite rod is an important graphite product. It is widely used, has the same excellent performance as other graphite products, high carbon content, high temperature resistance, and conducts electricity under high temperature. There are many good applications in the transportation industry and the energy management industry . At the same time, it is also widely used in its own industry, such as manufacturing graphite electrodes, anodes and cathodes, and other industries, such as manufacturing heating components, capacitors and capacitors into models, manufacturing graphite flats, etc. In addition, it is also widely used in metallurgy, mechanical engineering, chemical industry, electrochemistry and other industries as a special structure.
