Induction heaters are specialized devices used for various heating applications, from smelting precious metals to hardening small parts.
One of the critical aspects of these heaters is their operating frequency, which directly impacts their effectiveness and the types of applications they can handle.
What is the Maximum Frequency of Induction Heaters? (4 Key Points)
1. High-Frequency Induction Heating
The maximum frequency of induction heaters typically reaches around 400 kHz.
This high-frequency range is perfect for applications like smelting small amounts of precious metals and heating small to medium-sized parts with a thin hardened layer.
High-frequency induction heating operates within the range of 100 to 500 kHz.
This frequency range provides an effective hardening depth of 0.5 to 2 mm, making it ideal for fast, cost-effective, and compact heating solutions.
2. Medium-Frequency Induction Heating
Medium frequency induction heating machines operate within a frequency range of 1 kHz to 10 kHz.
This frequency range is suitable for large tempering, quenching, and heating of larger workpieces.
3. Super Audio Frequency Induction Heating
Super audio frequency induction heating power supplies use induction heating to heat electrically conductive materials.
The frequency of the electric current depends on the object size, material type, coupling, and penetration depth.
4. Induction Furnaces
Induction furnaces generally operate within a frequency range of 50 to 400 kHz.
Depending on the melting speed, type of material, and furnace volume, they can operate at even higher frequencies.
Lower frequencies have higher penetration into the metal, referred to as skin depth.
