Smart Induction Melting Furnace Solutions

Luoyang Judian specializes in the design and manufacture of medium frequency induction furnaces—an energy-efficient, clean, and high-performance solution for modern metal melting needs.

How Induction Melting Works

Induction melting uses electromagnetic fields to heat metal directly. A high-voltage primary coil generates a magnetic field that induces an electric current in the metal charge. This current produces heat, melting the material rapidly and uniformly. This method avoids combustion, reduces heat loss, and offers excellent temperature control.

Types of Induction Melting Furnaces

There are two main types of induction melting furnaces used in foundries and metalworking facilities:

1. Coreless Induction Furnace

The coreless furnace features a helical coil made of water-cooled copper tubing, housed in a steel shell. It operates across a wide frequency range (from 50 Hz to 10,000 Hz), making it suitable for melting ferrous and non-ferrous metals. As the metal melts, the induced current stirs the liquid alloy, ensuring even temperature and consistent chemical composition.

2. Channel Induction Furnace

Channel furnaces use an iron-core transformer with wound coils to generate localized heat, which is then transferred to a larger holding chamber. These units are often used for alloys with lower melting points or as holding furnaces for continuous pouring applications. They offer stable temperature retention and are ideal for long-run production.

Key Advantages of Induction Melting Furnaces

Our medium frequency induction melting furnaces provide significant benefits over traditional heating methods:

High Energy Efficiency: No combustion = less energy waste. Power is directly converted into heat in the metal, reducing energy bills.
Environmentally Friendly: Induction furnaces emit no harmful gases, making them ideal for facilities aiming to reduce emissions and meet global environmental standards.
Compact Design: Space-saving structure fits both small-scale foundries and large-scale industrial lines.
Low Metal Loss: Minimized oxidation and precise temperature control mean higher yield and cleaner melts.
Automation-Friendly: Easily integrated with digital control systems for temperature monitoring, material tracking, and automated pouring.

Metals suitable for induction melting include:

Ferrous metals: Steel, iron
Non-ferrous metals: Aluminum, copper, brass, zinc
Precious metals: Gold, silver

Smelting Tips for Maximum Efficiency

To get the best performance from your induction melting furnace, follow these best practices:

Use clean, rust-free, and dry metal scrap
Avoid slag inclusions and oxide contamination
Pre-compact loose materials to ensure even heating
Avoid sharp edges in large scrap pieces to prevent arc points
Always run the furnace at maximum rated power from the start for faster melting and improved energy usage

Monitoring voltage stability and choosing a properly sized unit can further reduce power consumption and improve melting cycles.
