Automatic temperature control by high frequency currents in the heating of pieces for quenching

Summary

• 1. The described method of automatic control of the process of heating and quenching of steel parts ensures a reliable temperature control, which is independent of the type of current in the electric network, of the shape of the part, and of the rate of the process.

• 2. The same system can be used for the automatic control of temperature with any other method of heating (gas flame, furnace, etc.).

• 3. The same system can find application in the automatic checking of many technological parameters that can be controlled by electric measurements.
