The purpose of induction heating furnace quenching process heating

1) Purpose of heating:

① When the heating is completed, the temperature of the surface layer of the part should be equal to or slightly higher than the quenching temperature;

②Get the appropriate heating layer depth.

2) The heating temperature and the depth of the heating layer depend on the following factors:

①The average effective power transmitted to the parts during the heating time;

② Heating time;

③Current frequency.

The greater the power and the longer the heating time (when other conditions are the same), the greater the depth of the heating layer and hardened layer of the part; if the heating power or time is insufficient, incomplete quenching or no quenching will be obtained. When using the time relay to adjust and control the heating time, check the time relay at least twice a month with a stopwatch (mechanical or electronic stopwatch). After the time relay is adjusted, it should be checked immediately with a mechanical stopwatch. The error of the time relay should be within ±0. Is, and the energy monitor should be in accordance with the requirements of the device.
