Graphite Electrodes

Graphite Electrode is an indispensable material used in the electric arc furnace steel making, for its excellent electrical conductivity and remarkable anti-thermal shock capability.

The current development of the modern electric arc furnace, increasingly larger capacity and higher current loads demand high quality electrodes which we offer through our principal Tokai Erftcarbon, guaranteed by more than 40 years working in this industry.

We offer graphite electrodes from 400 to 750 mm.

Productos - Plantas desgasificadoras para siderurgia

Steel Degassing Plants

MTAG Switzerland’s main expertise consists of supplying solutions for vacuum degassing of liquid steel using mechanical dry pumping systems.

The Vacuum Degassing process, an essential step in the secondary metallurgy of steel, allows for a more precise removal of certain gaseous elements to successfully attain even the most complicated steel grades. We are capable of designing and delivering an extensive range of installation starting from a 5t liquid steel ladle capacity up to 300t.
