The frequency range of an induction furnace typically operates between 50 to 400 kHz.
This range can extend beyond 400 kHz depending on specific operational requirements.
For smaller volumes of melts, the frequency tends to be higher.
Lower frequencies have a greater skin depth, which allows for more effective heating and melting of larger volumes of material.
5 Key Points About the Frequency Range of an Induction Furnace
1. Operational Frequency Range
The typical frequency range for an induction furnace is between 50 to 400 kHz.
2. Flexibility in Frequency
The frequency can extend beyond 400 kHz based on operational needs such as melting speed, material type, and furnace volume.
3. Higher Frequency for Smaller Volumes
Smaller melts often require higher frequencies.
4. Skin Depth and Heating Efficiency
Lower frequencies have a greater skin depth, which is crucial for heating and melting larger volumes of material.
5. Advantages of Induction Heating
Induction furnaces use electromagnetic induction to heat metal directly, reducing heat loss and enhancing thermal efficiency.
