HP400 Graphite electrodes are used for the smelting scrap steel in the electric arc furnace industry, so called “mini-mills”. They are also used in the refining of steel as well as in the non ferrous industries, where smelting processes are in use.

HP400 Graphite Electrode Rod for arc furnaces steelmaking

Synthetic Carbon Graphite Electrode are widely used in electric arc furnace (EAF) and ladle furnace (LF) for steel making production, ferroalloy production, silicon metal production and smelting processes. In addition to high temperature which can reach up to 3000℃ , these  Electrodes of Graphite UHP700 for scrap are featured with excellent mechanical strength, thermal expansion, thermal shock resistance and machinability.
