What aspects should be paid attention to in the power density of induction heating equipment?
1. Heating power density selection
The power of the power supply device depends on the power density value (P0) calculated in KW/cm2 on the surface of the workpiece and the primary heating area A in /cm2. The choice of power density depends on the heating surface area and its quenching technical conditions. The lower the current frequency, the smaller the diameter of the part and the shallower the required hardened layer depth, the greater the required power density.
2. Empirical method to select power density and heating time
In production practice, the current frequency of the workpiece and the required equipment power are often considered based on the existing production practice data.
3. Computer simulation selection
Due to the development of computer simulation technology, computer simulation software is now available for users to conduct simulation process tests through computer simulation to find the best equipment frequency and required power. For example, the computer software studies a Φ40mm shaft, the hardened layer depth is 2mm, and the recommended frequency range is 20-30KHZ.
