What is the difference between an electromagnetic induction heating board and an electromagnetic heating board?

What is the difference between electromagnetic induction heating and high-frequency electromagnetic heating? In fact, both devices are electromagnetic heaters and both use electromagnetic heating technology. The difference lies in the frequency level. Let's learn about it together!

Electromagnetic induction heating technology is currently mainly divided into 5 frequency types: low frequency, medium frequency, ultra-audio frequency, high frequency, and ultra-high frequency.

1. Low-frequency induction heating method: The lowest frequency, with a frequency range from power frequency (50HZ) to about 1KHZ, and the commonly used frequency is mostly power frequency. The heating depth is the deepest, and the heating thickness is the largest, about 10-20mm. It is mainly used for overall heating, annealing, tempering, and surface quenching of large workpieces.

2. Medium-frequency induction heating method: Frequency range is generally from about 1KHZ to 20KHZ, with a typical value of about 8KHZ. Heating depth and thickness
