DC Electric Arc Furnace 5000kVA Electroplating Sludge Smelting Heavy Metal Recovery Equipment
DC Electric Arc Furnace for Electroplating Sludge Smelting
The 5000kVA DC electric arc furnace is specially designed for the smelting treatment of electroplating sludge, a typical hazardous solid waste generated by electroplating and metal surface treatment plants. Using a stable DC arc as the heat source, the furnace melts the sludge at 1500-1600°C, recovering valuable heavy metals such as nickel, copper, chromium and zinc, while converting the remaining residue into inert vitrified slag that can be safely disposed of or reused in building materials.
Features
- Heavy metal recovery rate above 98% (Ni, Cu, Cr, Zn)
- Hazardous waste volume reduced by more than 85%
- Inert slag meets environmental landfill standards
- Stable DC arc with low electrode consumption
- Continuous automatic feeding for high throughput
- PLC + HMI automatic control with remote monitoring
