Product Description
Magnesium Slag DC Electric Arc Furnace 3000kVA
The furnace is a dedicated DC arc melting unit for magnesium reduction slag generated by the Pidgeon process and similar thermal reduction routes. Magnesium slag is fine, highly alkaline and carries residual metallic magnesium together with unreacted ferrosilicon, which makes it difficult to handle in conventional AC furnaces. The 3000kVA DC arc design delivers a concentrated, stable arc, so the slag is melted and reduced in one closed system instead of being stockpiled.
Why DC Arc Technology Suits Magnesium Slag
- Concentrated arc heat: the DC arc is stable and concentrated, reaching 1500-1650 C quickly even though magnesium slag is a poor conductor before melting.
- Double closed loop electrode control: the electrode lift is driven by PLC variable frequency control with real time current and voltage feedback, keeping the arc length constant as slag composition shifts.
- High natural power factor: 0.90 or above without a compensation bank, reducing reactive power penalties at the plant level.
- Lower electrode consumption: graphite electrode consumption is 30%-50% lower than a comparable AC furnace, and flicker, noise and harmonic disturbance are markedly reduced.
- Multi-electrode power supply: non conductive and partly molten charge can still be melted reliably, avoiding the bridging and dead zones typical of AC operation.
Process Flow
- Magnesium slag is crushed, screened and blended with a small amount of flux and reductant in a batching station.
- Automatic feeding delivers the blend to the furnace through a sealed charging port with dust suppression.
- The DC arc melts the charge into a fluid pool; metal and alloy phases settle to the bottom while the oxidised slag floats.
- Metal is tapped through the lower tapping hole for ingot casting or granulation; slag is tapped forward through the slag notch for vitrification, cooling and downstream use.
- Off gas enters a settling chamber and bag filter, with emission kept below 10 mg/m3.
