Medium Frequency Induction Furnace: Structure, Power Supply, and Technical Parameters
2024.10.23
A medium frequency induction furnace is one of the most widely used melting solutions in the foundry and metal casting industry. It offers fast melting speed, high energy efficiency, and precise temperature control, making it an ideal choice for steel, iron, copper, aluminum, and other non-ferrous alloys.
Main Components of a Medium Frequency Induction Furnace
Heavy-duty steel shell body for maximum durability
Induction coil
Magnetic field shielding system, which improves energy efficiency and reduces leakage
The steel shell furnace is generally preferred for larger capacities and long-term industrial use, while the aluminum shell design is more economical and compact.
Power Supply Options
The performance of a medium frequency induction furnace largely depends on its power supply system. Depending on production requirements, buyers can choose:
KGPS frequency power supply
12-pulse or 24-pulse rectifier power supply (for reduced harmonics and stable operation)
IGBT frequency power supply (modern design with high efficiency and easy maintenance)
Control modes are flexible and can be configured as local control, touch screen operation, remote control, or computer-based control.
