Small DC Electric ARC Furnace (EAF)

We can produce one electrode and three electrodes DC electric arc furnace, this will base on the equipment’s producing capacity. Whether melting metal or nonmetal, DC arc furnace can save more than 20% energy than AC furnace, because melting material will be turned up from bottom following electric current just like mixing, so the melting speed will be higher. Such as melting one ton scrap steel powder, the consumption of DC ARC furnace will be 610 KWh, but induction furnace will be 1100 KWh.

If you need larger furnace, it should be AC equipment, because the rectifier system will be very complex and expensive, but AC will be simple and easy to maintain.

In a word, we can produce DC Electric ARC furnace (EAF), AC Electric ARC furnace (EAF) and Submerged ARC furnace (SAF), this will base on customer’s raw material, producing capacity, and products, if you want to melt steel, scrap iron powder, Silicon, Ferro-silicon, Ferro-chrome, Ferro-manganese, Ferro-tungsten and other alloys, please feel free to inquire us the details.
