Electric furnaces and metallurgical industry : Carbon electrodes, as important electrode material in electric furnaces, are widely used in industries such as steel and aluminum electrolysis. Carbon electrodes can complete the smelting and purification of metals by electric arc heating and electrolysis process
1. In the metallurgical industry, carbon electrode is also commonly used in the copper smelting process as anode to achieve the preparation and purification of electrolytic copper
Chemical industry : In chlor-alkali production, carbon electrodes, as important electrode materials in chlor-alkali electrolysis, are used for electrolyzing brine and producing chemical products such as sodium hydroxide
Glass industry : Carbon electrodes are used as electrode materials in glass furnaces for heating and melting raw glass
Other applications : Carbon electrodes are also used in aluminum electrolysis, capacitor manufacturing, semiconductor manufacturing and other fields. For example, in aluminum electrolysis, carbon electrodes provide the necessary path of current to ensure the smooth progress of the electrolysis process
The advantages and disadvantages of carbon electrodes
Advantages :
High-temperature oxidation resistance : Carbon electrodes have excellent oxidation resistance at high temperatures, which can protect the electrode material itself and extend its service life
Good electrical conductivity : Ensure smooth current flow and uniform electrolyte
Strong corrosion resistance : Can work stably for a long time in strong acids, strong alkalis and other media
High mechanical strength : Capable of withstanding heavy pressure and vibration at high temperatures
Disadvantages :
Higher cost : The construction cost of the graphitization workshop is high and the electricity consumption is large, resulting in increased cost
Diameter limitation : Currently, the diameter of graphite electrodes produced domestically is relatively small, which limits their application in large electric arc furnaces
