Induksjonsvarmeutstyr

Medium-frequency Induction furnaces are used for metal smelting, induction heating, and industrial heat treatment.

A medium-frequency Induction furnace is an industrial device that uses a medium-frequency power supply to generate an alternating electromagnetic field, directly heating and smelting metal through the principle of electromagnetic induction. With its advantages of rapid heating, high thermal efficiency, precise temperature control, and clean and environmentally friendly operation, medium-frequency furnaces are widely used in industries such as casting, metallurgy, machinery manufacturing, metal recycling, og varmebehandling.

Compared to traditional fuel furnaces and industrial frequency equipment, medium-frequency furnaces offer higher energy efficiency, shorter production cycles, and better heating uniformity, making them essential equipment for modern metal processing and smelting production.

What is a Medium Frequency Induction Furnace?

A medium frequency induction furnace is an electric furnace that uses medium frequency induction heating technology. It typically consists of a medium frequency power supply, induction coils, a furnace body, and a cooling system. The equipment heats the metal itself through induced current, achieving rapid, uniform, and efficient heating or melting.

Main applications include:

• Metal melting
• Metal holding
• Forging heating
• Heat treatment
• Metal recycling and regeneration

Main application areas

Medium frequency furnaces are widely used in the following industries:

Ofte stilte spørsmål (FAQ)

1. What is the working principle of induction heating equipment?

It generates current inside the workpiece through electromagnetic induction, thereby achieving rapid heating.

2. What is a melting furnace?

A melting furnace is a furnace that uses a high-temperature heat source to heat and melt the object to be melted.

3. What is an induction furnace?

Working principle: An induction furnace consists of a non-conductive crucible containing the metal to be melted and a copper coil surrounding the crucible. A strong alternating current passes through the copper coil. The coil generates a rapidly reversing magnetic field that can penetrate metal.

4. What are the two types of induction furnaces?

Induction furnaces are electric furnaces that use electromagnetic induction to heat and melt metals. They are commonly used in the foundry industry for melting and casting metals such as iron, steel, copper, aluminum, and precious metals. Induction furnaces are mainly divided into two types: coreless and trough type.

5. Working Principle of Medium Frequency Induction Furnace

A medium frequency induction furnace is a device that rectifies three-phase industrial frequency AC power into DC power, and then rectifies the DC power into an adjustable current to power the AC power flowing through the capacitor and induction coil, thereby generating a high-density current in the induction coil.
