Graphite electrode is a high-temperature resistant graphite conductive material, which is widely used in various industrial furnaces. The raw materials of graphite electrodes are finally made into finished graphite electrodes that meet customer needs through a series of production processes. Due to the characteristics of raw materials and the characteristics of graphite electrodes, the production cycle of graphite electrodes is generally longer. Rongsheng graphite electrode suppliers sell high-quality graphite electrode products. Learn more about the Application of UHP Graphite Electrodes. Please contact RS or email us directly.
Classification of Graphite Electrodes
- Ordinary power graphite electrode (RP);
- High power graphite electrode (HP);
- Quasi ultra-high power graphite electrode (SHP);
- Ultra-high power graphite electrode (UHP).
Application of UHP Graphite Electrodes
The graphite electrode has the advantages of low resistivity, low ash content, uniform structure, good thermal shock resistance, high mechanical strength, and low thermal expansion coefficient. The UHP electrode and nipples are precisely matched. It is an excellent material for electric furnace steelmaking and smelting in a mineral furnace.
(1) Used in an electric arc steelmaking furnace
Graphite electrode materials are mainly used in electric furnace steelmaking. Electric furnace steelmaking is to use the research graphite electrode to introduce working current into the furnace. A strong current can affect the arc discharge through these gas environments at the lower end of the electrode, and use the heat generated by the arc to smelt. According to the capacity of the electric furnace, graphite electrodes with different diameters are used. In order to use the electrodes continuously, the electrodes are connected by electrode nipples. Graphite electrodes for steel making account for about 70 to 80% of the total amount of graphite electrodes.
(2) Used in ore heating furnace
Mine-fired electric furnaces are mainly used to produce ferroalloys, pure silicon, yellow phosphorus, matte, and calcium carbide. Its characteristic is that the lower part of the conductive electrode is buried in the charge. Therefore, in addition to the heat generated by the arc between the electric plate and the charge, heat is also generated by the resistance of the charge when the current passes through the charge. It takes about 150kg of graphite per ton of silicon, and about 40kg of graphite electrode per ton of yellow phosphorus.
(3) Used in a resistance furnace
In the production process, graphitization furnaces, melting glass furnaces and electric furnaces for producing silicon carbide are all resistance furnaces. The materials contained in these furnaces are both a heating resistor and an object to be heated. Generally, graphite electrodes for electrical conduction are embedded in the furnace headwall at the end of the resistance furnace, and the graphite electrodes used here are not continuously consumed.
(4) A large number of graphite electrode blanks can also be processed into various shaped products such as various crucibles, graphite boats, hot die-casting molds, and heating elements for vacuum electric furnaces. For example, in the quartz glass industry, every 1t of the fused tube requires 10t of graphite electrode blank; for every 1t of quartz brick, 100kg of graphite electrode blank is consumed.
Rongsheng Graphite Electrodes Supplier
Rongsheng graphite electrode supplier has sold graphite electrodes to Russia, South Africa, Chile, and other countries and regions. Graphite electrode is mainly made of petroleum coke and needle coke as raw materials, coal pitch as binder, and is made by calcination, batching, kneading, pressing, roasting, graphitization and machining. The graphite electrode is a conductor that releases electrical energy in the form of an arc to heat and melt the charge in the arc furnace. The use of graphite electrodes is basically the same as that of UHP graphite electrodes, except that UHP graphite electrodes can be used in electric arc furnaces under ultra-high power voltages.
