Small DC Electric ARC Furnace (EAF)
We specially focus on small DC ARC furnace, because it is safe, has high efficiency and Low energy consumption, the higher temperature can melt most of metal and nonmetal quickly.
EAF is workable for adding any material, because melting material will be writhed follow electric current, the material can be mixed uniformly.
Whether melting metal or nonmetal, DC ARC furnace will save more energy than AC furnace, because melting material will be rolled up from bottom follow with electric current (Fully Stirred), so the melting speed will be quickly, also it is workable to add any material and adjust the content of chemical element.
EAF also be named Submerged Arc Furnace, because if melt non-conductor product, the firing point will under the material, so the name means that electric arc is submerged in the material.
- Equipment parts of DC 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.
