Advantages of Induction Furnace over Resistance Furnace in Melting Aluminum:

Compared to resistance furnaces, medium-frequency (MF) furnaces offer significant advantages for aluminum melting:

High Efficiency & Energy Savings: Electromagnetic induction directly heats aluminum, achieving 60%-75% thermal efficiency (vs. 30%-50% for resistance furnaces), reducing power consumption by 20%-30% (~500-550 kWh per ton of aluminum).

Faster Melting: Heating speeds are 2-3 times faster, melting 1 ton of aluminum in just 40-60 minutes.

Lower Metal Loss: Oxidation losses are only 1%-2% (vs. 3%-5% in resistance furnaces), improving metal yield.

Precise Temperature Control: Uniform heating (±5°C), ideal for alloying processes.

Flexibility & Durability: Can start/stop instantly, suitable for batch production; induction coils last longer than resistance heating elements.

Eco-Friendly & Cost-Effective: Lower long-term operating costs, with ROI in 1-2 years.

Conclusion: MF furnaces are ideal for small-to-medium batch, high-quality aluminum melting, making them a superior alternative to resistance furnaces.
