Product Features
• Optimized for ESR Processes
Engineered to provide a low no-load voltage and minimal impedance voltage, perfectly suited for the continuous, stable melting required in electroslag refining.
• Precision Voltage Regulation
Available with multiple tapping levels to suit various smelting stages. We offer three regulation modes:
1. Off-circuit tap changing (OCTC)
2. Excitation-based no-load regulation
3. On-load tap changer (OLTC) for uninterrupted operation.
• Robust Construction
Featuring a reactor-less design specifically for slag melting, reducing energy loss and footprint.
• Advanced Cooling Systems
Depending on capacity, we offer natural air cooling (dry type), oil-immersed self-cooling, or forced oil-water cooling (FOWS) for heavy-duty industrial cycles.
• Versatile Applications
Ideal for producing large high-quality alloy ingots, flat slabs, and complex shaped castings. We also specialize in single phase titanium slag furnace transformer designs for specific smelting needs.
