Cum se alege un masina de incalzit prin inductie?

Different workpiece heating options The choice of induction heating machine is also different. You can see the following requirements:

1. The shape and size of the heated workpiece

For example, for large workpieces, bar materials, and solid materials, induction heating machines with relatively high power and low frequency should be used;

For small workpieces, such as pipes, plates, gears, etc., use induction heating machines with relatively low power and high frequency.

2. The depth and area of ​​heating

The heating depth is deep, the area is large, and the overall heating should be an induction heating machine with high power and low frequency;

The heating depth is shallow, the area is small, and the heating is localized. The induction heating machine with relatively low power and high frequency is selected.

Third, the heating rate of the workpiece

If the heating speed is fast, an induction heating machine with relatively large power and relatively low frequency should be used.

Fourth, process requirements

Generally speaking, for processes such as quenching and welding, you can choose a lower power and a higher frequency;

For tempering, annealing and other processes, the relative power should be larger and the frequency should be lower;

Red punching, hot forging, smelting, etc., require a process with a good diathermy effect, so the power should be larger and the frequency should be lower.

Five, it depends on the material of the workpiece

Among the metal materials, the higher melting point is relatively large, the lower melting point is relatively small; the lower resistivity is higher, and the higher resistivity is lower.
