Difference between Medium and High Frequency Induction Heating Equipment
Induction heating equipment with a frequency of 1-10Khz is usually regarded as medium-frequency induction heating equipment, and induction heating equipment with a frequency above 50Khz as high-frequency induction heating equipment.
Different Quenching Depth
Affected by the frequency of induction heating equipment, the quenching depth of the two is also different. The quenching depth of medium frequency induction heating equipment is generally 3.5-6mm, while that of high frequency induction heating equipment is 1.2-1.5mm.
Different Diathermy Diameters
Medium frequency induction heating equipment has great advantages in the diathermy of workpieces. It is mainly used for diathermic heat treatment of workpieces. It can perform diathermic heat treatment on workpieces with a diameter of 45-90mm. However, high-frequency induction heating equipment can only dilute the thin and small workpieces.
Induction Heating VS Other Heating Methods
Induction heating is different from some common heating methods in that it does not rely on convection and radiation to transfer heat to the surface of the product. Instead, the surface of the product generates heat through current, and then the heat from the surface of the product is transferred to the product through heat conduction. The depth of direct heating using induction current depends on the electrical reference depth.
Unlike some combustion methods, induction heating can be precisely controlled regardless of batch size. By changing the current, voltage and frequency of the induction coil, fine-tuned engineering heating can be achieved, which is very suitable for precision applications such as surface quenching, quenching and tempering, and annealing. The precise heating control provided by induction is unparalleled. In addition, using the same heating principle as the vacuum crucible heating application, induction heating can be carried out in the atmosphere for continuous application. For example, bright annealing of stainless steel tubes.
