What is the difference between a high frequency melting furnace and an intermediate frequency melting furnace

Intermediate frequency induction heating: The current frequency is 500～10000 Hz (Hertz), and 5 kg-60 tons of various metals are smelted. It has the characteristics of fast speed and high efficiency.

The intermediate frequency melting furnace has a large volume, mature technology, large output power and low failure rate.

The effective hardening depth of intermediate frequency heating is 2-10 mm (millimeters), which is mainly used for parts that require a deeper hardening layer, such as medium-modulus gears, large-modulus gears, and shafts with larger diameters.

High-frequency induction heating: The current frequency is 100～500 kHz (kilohertz), suitable for smelting 1-5 kg of precious metals, fast, cheap, small in size, and small in area

The effective hardening depth of high frequency heating is 0.5-2 mm (millimeters), which is mainly used for small and medium-sized parts, such as small modulus gears, small and medium-sized shaft quenching, etc.
