Product Overview
The Medium Frequency Induction Melting Furnace (MFIMF) is an industrial furnace that utilizes the principle of medium-frequency electromagnetic induction for rapid heating and melting of metals. It is widely applied in casting, alloy smelting, non-ferrous metal melting, and special metal smelting industries.
Compared to traditional fuel-fired furnaces or power-frequency induction furnaces, the medium frequency induction melting furnace offers a more balanced performance in terms of heating efficiency, temperature control precision, and metal composition stability, making it one of the most commonly used melting units for modern casting and metal processing enterprises.
Working Principle
The medium frequency induction melting furnace converts power-frequency AC into medium-frequency current within a specific frequency range via a medium-frequency power supply, which is then delivered to the induction coil:
- An alternating electromagnetic field is generated within the coil.
- The electromagnetic field induces eddy currents inside the metal charge.
- The eddy currents generate heat due to the metal's own electrical resistance.
- The metal heats directly from the inside and gradually melts.
This heating method is a non-contact process where energy acts directly on the metal body, reducing intermediate heat losses and making the melting process more efficient and controllable.
