► Description
Graphite electrodes are made of mixed needle coke and coal pitch, to be extruded, baked, impregnated, graphitized and machined for use as conductive material on EAF (Electric Arc Furnace) and LF (Ladle Furnace) for steelmaking.
In the steelmaking process, the EAF method recycles used iron scrap by melting it at a temperature of about 1600 ℃ in an electric arc furnace. Graphite electrodes, a kind of conductor, are an essential component in this kind of furnace.
► Applications
For AC Furnaces, they require 3 columns of graphite electrodes, and mostly use diameter from 400 to 700 mm (16-28 inch).
For DC Furnaces, they require 1 column of graphite electrodes, and the maximum diameter is up to 800 mm (22-32 inch).
For LF, they have a small capacity than DC Furnaces, and mostly use diameter from 200 to 450 mm (8-18 inch).
