1. Introduction
Modern metal processing demands technology that’s efficient, precise, and sustainable. Electroheat Induction delivers exactly that — advanced induction melting furnaces built for speed, energy savings, and consistent performance.
Powered by cutting-edge IGBT technology, our systems ensure faster, uniform melting with lower environmental impact, making them the trusted choice for foundries, refineries, and industrial plants worldwide.
2. What Is an Induction Melting Furnace?
An induction melting furnace operates by utilizing electromagnetic induction to generate thermal energy directly within a conductive metal charge, facilitating the melting of diverse materials including steel, iron, copper, aluminum, brass, bronze, silicon, gold, and silver. This non-contact heating methodology offers several distinct advantages:
- Clean operation, free from combustion gases or fuel contamination.
- Uniform melting and precise temperature control.
- Reduced dust and emissions compared to traditional methods.
Typical operational ranges include:
- Output Power: 50 kW – 10,000 kW
- Melting Capacity: 50 kg – 15 tons
3. Key Features and Technological Advantages
Electroheat’s industrial induction melting furnaces are engineered for maximum efficiency and productivity. The table below outlines their core features and the distinct advantages each provides:
| Feature | Advantage |
| Advanced IGBT Power Controls | Improved melting rates and reduced electrical losses. |
| Optimized Coil Winding | Higher energy transfer and uniform heating. |
| Smart Power Circuitry | Maintains stable load and prevents over-demand. |
| Dual Cooling Turns | Even temperature distribution and longer coil life. |
| Magnetic Shunts | Lower stray losses and overheating prevention. |
| Compact Design | Space-saving layout ideal for modern facilities. |
