UHP graphite electrode refers to a kind of ultra high power graphite based electricity conduction material, which adopts petroleum coke, needle shaped coke as aggregate, coal asphalt as binder, and are processed by complex crafts such as calcining, crushing, milling, batching, mixing, forming, roasting, impregnating, graphitization and mechanical processing. UHP graphite electrode is usually used as conductor of large capacity electric arc furnace. The intense electric arc generated between UHP graphite electrode and bottom electrode can heat and melt furnace load.
Rongsheng Kiln Refractory Company is a professional graphite electrode manufacturer in China. Our company always devoted into manufacturing high quality graphite electrodes for all customers that are demanded for their ease of use, long time service and options for wide ranging usages. Besides, our company also provide RP Graphite Electrodes, HP Graphite Electrode that you can choose from Rongsheng Group.
Ultra-high-power graphite electrodes (EHSP-UHP) are manufactured for operation at currents with a density of more than 25A / cm2, and the graphite electrode UHP is mainly used for for ultra-high-power arc furnaces and powerful ladle furnaces.
(1) Used in Electric Arc Furnace
Electric furnace steelmaking mill is the largest user of graphite electrodes. Graphite electrodes used in steelmaking accounts for 70%-80% of the total graphite electrodes production. Graphite electrodes are used to conduct electric current into electric furnace, electric arcs generated between electrodes end and loaded materials can release large amount of heat for high temperature smelting.
(2) Used in Mine Electric Furnace
The ore electric furnace is mainly used for the production of industrial silicon and yellow phosphorus. It features in that the lower part of the conductive electrode is buried in the charge, electric arcs are generated in material layer, and the heat released in the charge is used for the smelting. Mine electric furnaces which require high electric current density need to use graphite electrodes. For example, about 100 kg of graphite electrode is consumed for every t of silicon yield, and about 40 kg of graphite electrode is consumed for each t of yellow phosphorus production.
