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?

  • As compared to Diode rectifier, Thyristor rectifier has the following advantages:
  • Realize accurate output regulation by SCR triggering control
  • Accurate output voltage or current regulation
  • Intelligent digital controller
  • Self adaptive to input grid fluctuation
