Product Description of High Conductivity RP HP UHP Graphite Electrode For EAF Electric Arc Furnace With Manufacturer Price
Graphite electrode is mainly made of Petroleum coke and needle coke as raw materials and coal tar pitch as binder after calcination, batching, kneading, molding, roasting, graphitization and machining. It is a conductor that releases electric energy in the form of arc to heat and melt furnace materials. According to its quality indicators, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode.
Advantages of Graphite Electrode
1, The process of graphite electrode production is simple, high efficiency, small graphite loss
2, Fast processing speed, lower production costs
3, Different sizes available, including large diameter
4, Our graphite electrodes are very durable and have a long service life
5,Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capability, precise machining accuracy, especially with low sulphur and low ash will not give steel second time
Graphite Electrode Application
1 for EAF arc furnace; 2 for ore-thermal furnace; for the resistance furnace; 3 for the production of profiled graphite products; 4 for the production of shaped graphite products. Diameter of electrodes: from 75 to 800mm. We can produce various specifications in accordance with customer requirements. Our advantages: Manufacturer from China; Buy directly from the factory; High-quality products; Profitable price.
