Graphite electrodes for nickel smelting

Graphite electrodes are widely used in the nickel smelting industry due to their excellent thermal and electrical conductivity, high mechanical strength, and resistance to chemical corrosion. Nickel smelting involves the use of high-temperature furnaces and reactors, where graphite electrodes are used to provide the electrical energy required to melt and process the nickel ore.

Electric arc furnaces (EAFs): Graphite electrodes are commonly used in EAFs for nickel smelting. EAFs are used to melt the nickel ore, as well as other materials such as iron ore and coke or coal. Graphite electrodes are used to generate an electric arc between the electrodes and the raw materials, which generates heat and melts the materials.

AOD converters: Graphite electrodes are also used in argon oxygen decarburization (AOD) converters, which are used in the refining process of nickel. AOD converters use a combination of argon gas and oxygen to remove impurities from the nickel and improve its quality. Graphite electrodes are used to provide the electric current required for the process.
