application
(1) For steel making in EAF/LF
Graphite electrode is mainly used in Electric arc furnace for steel smelting. When graphite electrode is working in EAF, the current will be introduced by graphite electrode into the furnace, and there will be heat source which is generated by electric arc between electrode end and furnace charge for smelting.
(2) For producing metallic silicon and yellow phosphorus in submerged arc furnace
Some carbon electrode with large size (eg.700mm-1400mm) is used for producing metallic silicon and yellow phosphorus in submerged arc furnace. The lower part of the carbon electrode is buried in the charge, forms an arc in the charge layer, the material will be smelted by the heat energy generated by the resistance of the charge. For example, about 100kg of graphite electrode is consumed for 1 ton of metallic silicon.
(3)For producing corundum in electric furnace
(4)Used for processing special-shaped graphite products
The blank of graphite electrode is also used to process various special-shaped graphite prod
