What are the application advantages of graphite electrodes in various industries?
Iron and steel industry: In the steel industry, graphite electrodes are mainly used for electric arc furnace steelmaking. The electric arc furnace uses the arc generated between the graphite electrode and the charge to melt the metal to achieve the purpose of refining molten steel. In this process, the graphite electrode plays a dual role of conductivity and high temperature resistance, ensuring the smooth progress of the electric furnace steelmaking process.
