How to choose a high-frequency machine for induction heating equipment?

Working conditions of high frequency machine of induction heating equipment

The shape and size of the workpiece to be heated is large, bar stock, or solid material. Induction heating equipment with relatively high power and low frequency should be selected. For small workpieces, pipes, plates, gears, etc., induction heating equipment with relatively low power and high frequency is selected.

1) Required heating speed

If the heating speed is required to be fast, induction heating equipment with relatively large power and relatively high frequency should be selected.

2) Depth and area to be heated

3) For deep heating depth, large area, and overall heating, induction heating equipment with high power and low frequency should be selected; for shallow heating depth, small area, and local heating, induction heating equipment with relatively low power and high frequency should be selected.

4) The connection distance between the sensing component and the device

The connection is long and even requires the use of water-cooled cables, so induction heating equipment with higher power should be used.

5)Continuous working time of the equipment

If the continuous working time is long, induction heating equipment with slightly larger power should be selected.

6) Process requirements

Generally speaking, for quenching, welding and other processes, you can choose a smaller power and a higher frequency; for annealing, tempering and other processes, you can choose a higher power and a lower frequency; for red punching, thermal forging, smelting, etc., you need to For a process with good heat penetration effect, the power should be larger and the frequency should be lower.

7) Material of work piece

Among metal materials, those with higher melting points should use higher power, and those with low melting points should use less power; those with small resistivity should use higher power, and those with high resistivity should use less power.
