Graphite is widely used in the electrical industry as electrode, brush, carbon rod, carbon tube, positive electrode of mercury rectifier, graphite gasket, telephone parts, television picture tube coating and so on. Among them, graphite rod electrolysis is the most widely used. When smelting various alloy steel and iron alloy, graphite rod counter electrode is used to generate electric arc, so that electric energy is converted into heat energy, and the temperature rises to about 2000 degrees, so as to achieve the purpose of smelting or reaction.

ADVANTAGES OF GRAPHITE ROD ELECTRODE



Graphite rod thermal conductivity and electrical conductivity is very high, such as: thermal conductivity is different from the general metal materials, it is greater than iron, lead, steel and other metal materials, and will increase with the temperature, the thermal conductivity is reduced.
