An induction furnace is an electric furnace that uses electromagnetic induction to melt metal. Instead of using a flame or fuel, it heats the metal using a high-frequency alternating current that creates eddy currents within the metal, causing it to heat up and eventually melt.

It is primarily used for metal casting and the steel melting industry

How it Works

• An alternating current pass through a coil around a crucible.
• This creates a magnetic field, which induces eddy currents in the metal inside the crucible.
• The resistance of the metal to these currents generates intense heat, melting the metal.

Advantages

• Faster Melting Time
• High-frequency currents melt metal quickly.
• Ideal for high-volume production.
• High Energy Efficiency:
• Converts electrical energy directly into heat inside the metal.
• Minimal heat loss compared to gas or arc furnaces.
• Clean and Environmentally Friendly:
• No combustion → no harmful emissions (CO₂, SO₂, etc.).
• Suitable for environments with strict environmental regulations.

Characteristics

• Temperature: Up to 1800 °C
• This furnace is capable of melting precious metals (Au, Ag, Pt).
• Temperature control via thermocouple or optical sensor
• Volume: approximately 1 liter, Processed quantity: approximately 1 kg
• Gas flow to prevent oxidation, Water cooling if necessary

Applications

• Metal casting and foundries
• Steel production.
• Jewelry making.
• Recycling of metals.
• Precision melting for aerospace and automotive parts.
