300 X1800mm Graphite Electrode with Nipples for Eaf for Welding Cast Steel

Product Description

Product Description
Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking,
Yellow phosphorus furnace, Industrial silicon furnace or melting copper. They are presently
the only products available that have high levels of electrical conductivity and the capability
of sustaining the extremely high levels of heat generated in this demanding environment.
