DC ORE (arc melting) furnace bottom part of the special structure is that, both the anode and the bottom melting crucible, requires bottom should have good electrical conductivity and durability.
DC electric furnace compared with the exchange, has the following advantages:
A single electrode DC furnace, the electrode with low power consumption, electrode consumption less.
2 DC electric power factor of the natural high, in the case without compensation, power factor up to 0.9.
a) DC electric flicker effect and has a low noise, especially noise when submerged arc reduced by 20 decibels (dB) or more.
b) used a dc furnace electrode device structure is simple, easy to install dust hoods to control smoke.
c) DC electric furnace electrode core temperature is high, the heat concentration, easy-to-deep electrode, bottom up is not easy, suitable for high melting point than the product of smelting.
3 DC Furnace role of both the molten salt electrolysis, to speed up the reduction of metal oxides, metal recovery rate.
4 DC arc stability for AC arc, work, three-phase current balance, reduce interference on the power grid, while running stable, easy to operate
