Product Description

Applicable for various DC furnace where DC (direct current) power supply is needed, including all kinds of vacuum resistance furnace, plasma furnace, vacuum arc furnace, etc used for melting of Titanium, Niobium, Zirconium, Vanadium, Tungsten, Molybdenum, and other metals that are difficult to dissolve, high temperature alloy and alloy steels.

In a DC furnace system only a single electrode is used, and the bottom of the vessel serves as anode. This arc furnace achieves energy savings in terms of power unit. In addition, it also has other features, like higher melting efficiency and extended hearth life.

Recommended Rectifier

  • High power SCR Rectifier
  • Small power IGBT Rectifier

Why Use Thyristor Rectifier Technology?
