[ 3 ] Graphitized Cathode Block for Aluminium Smelting, SK-B^®

Graphitized Cathode Block for Aluminium Smelting, SK-B^®

for

Aluminium Electrolytic Cells

Our graphitized cathode block is used in the electrolytic cells of aluminium smelting plants.
It serves as the cathode block during the electrolysis process that extracts aluminium from alumina.

[ 4 ] Graphite Electrodes

Artificial Graphite Electrodes

for

Electric Arc Furnaces for Steelmaking Ladle Furnaces

Artificial Graphite Electrodes are consumable components used in electric arc furnaces to melt steel scrap for recycling.
They play an essential role in promoting a circular economy for iron resources.

Compared to producing steel from iron ore, recycling steel emits significantly less CO₂.
As such, our electrodes also contribute to carbon neutrality.
