Graphite Electrode Introduction Graphite Electrodes for sale from RS Factory are a high temperature resistant graphite conductive refractory material used in the metallurgical industry.Graphite Electrode is made of petroleum coke, bituminous coke as aggregates,coal tar pitch as binders,after raw material calcination,crushing and milling,batching,kneading,molding,roasting,impregnation,graphitization and machining,which is also known as artificial graphite electrodes in order to distinguish from natural graphite electrodes made of natural graphite.If you are looking for high quality graphite electrodes for sale,Contact us for more details. Graphite Electrodes Classification Graphite Electrodes for sale can be divided into regular power graphite electrode,high power graphite electrode and ultra high power graphite electrode based on its quality index.There are also other grades including regular power （RP）,normal power（HP）,and medium power or（UHP）.However,these grades are less commonly used Regular power graphite electrodes（RP） are mainly used in ordinary power electric furnaces for steel making,silicon refining,and yellow phosphorus. High-power graphite electrodes（HP） are primarily applied in the high-power electric arc furnaces for steel making. Ultra high power graphite electrodes（UHP） are mainly used in the ultra high power steelmaking electric arc furnaces.
Graphite Electrodes Uses
As a conductive electrode, not only can graphite electrodes be used in steelmaking electric arc furnaces, refining furnaces, but also in industrial silicon furnaces, yellow phosphorus furnaces, and corundum furnaces. The uses of graphite electrodes are mainly as follows:
1.Electric Arc Furnace
Graphite electrodes are the most widely used in electric furnace steelmaking. China’s electric furnace steel production accounted for about 18% of crude steel production, and the graphite electrode for steelmaking accounts for 70%-80% of the total amount of graphite electrodes. Electric furnace steelmaking uses a graphite electrode to introduce a current into the furnace and uses the high-temperature heat source generated by an arc between electrical extremes and the charge for smelting.
2.Ore Electric Furnace
The ore electric furnace is mainly used for the production of industrial silicon and yellow phosphorus which is characterized by the lower part of the conductive electrode buried in the charge, the formation of arc in the material layer, and the use of the heat emitted by the resistance of the charge itself to heat the charge, wherein the higher density current electric furnaces needs graphite electrodes. For example, about 100 kg of graphite electrode is consumed for every 1t of silicon produced, and about 40 kg of graphite electrode is consumed for each 1t of yellow phosphorus.
3.Electric Resistance Furnace
The graphitization furnace for producing graphite products, the melting furnace for melting glass, and the electric furnace for producing silicon carbide belong to electric resistance furnaces. The materials contained in the furnace are both heating resistors and objects to be heated. Usually, graphite electrodes for electric conduction are embedded in the furnace head wall of the electric resistance furnace end, the graphite electrode used here is not continuously consumed.
4.For The Preparation of Shaped Graphite Products
The graphite electrode blank is also used to process a variety of shaped graphite products such as enamel, mold, boat and heating element. For example, in the quartz glass industry, for every 1 ton of electrofusion tube, 10 t graphite electrode blank is required; for every 1 t of quartz brick, 100 kg graphite electrode blank is consumed.
