Common graphite electrode is a key material used in electric furnace smelting. RP stands for "Regular Power" and represents a specification for graphite electrodes. Graphite electrode is a conductive material made of coke and graphite particles by baking, shearing, molding, graphitization and other processes.

The graphite electrode has high thermal stability, electrical conductivity, mechanical strength and oxidation resistance, which is suitable for the smelting process in high temperature environment. It is widely used in electric furnace smelting of steel, non-ferrous metals, silicon and other industries, and is one of the core equipment of electric furnace smelting technology.

As a conductive material of electric furnace, graphite electrode plays an important role in the smelting process. Its main functions include:
(1) Conduction: The graphite electrode can effectively transfer electrical energy to the smelting material, so that it reaches the required temperature.
2 Resistance to arc erosion: smelting process will produce a strong arc, graphite electrode can withstand the high temperature and high energy of the arc, with good resistance to arc erosion performance.
3. Responsible for stabilizing the furnace bottom: The graphite electrode plays a role in stabilizing the furnace bottom structure during the smelting process by contacting with the smelting furnace bottom to ensure the stability of the smelting process.
4. Provide chemical reaction conditions required for smelting reaction: graphite electrode can produce some gases and elements required for chemical reaction in the smelting process to promote the smelting reaction.

In general, graphite electrode RP is widely used in the electric furnace smelting industry, and its excellent electrical conductivity, high temperature stability and erosion resistance make it an important part of electric furnace smelting. Different specifications of graphite electrodes are suitable for different types of smelting processes and equipment needs, and play an important role in improving smelting efficiency, reducing energy consumption and improving product quality.
