Abstract
To provide a heat treatment providing a product with quality as desired, high frequency induction heating treatment equipment capable of temperature control to provide such heat treatment includes temperature controlling means for adjusting in temperature an object to be treated, and quenching means for determining when the object heated should be cooled. The temperature controlling means includes heating means, temperature measuring means involved in temperature control, and temperature adjusting means. The quenching means includes temperature measuring means involved in quenching, and heat treatment adjusting means.
Claims13
High frequency induction heating treatment equipment employing induction heating to heat and thus quench and harden an object to be treated, comprising:
- temperature controlling means for adjusting said object in temperature, and;
- quenching means for determining when said object heated should be cooled.
A high frequency induction heating treatment method employing induction heating to heat and thus quench and harden an object to be treated, comprising:
- a temperature controlling step of adjusting said object in temperature, and;
- a quench controlling step of determining when said object heated should be cooled, wherein:
- said temperature controlling step includes
- a heating step of heating said object through induction heating,
- a temperature measuring step involved in temperature control, of measuring in temperature a portion of said object that is heated, and
- a temperature adjusting step of outputting a temperature control signal, as based on information of said temperature measured, to control heating said object;
- and
- said quench controlling step (includes
- a temperature measuring step involved in quenching, of measuring in temperature a portion located away from said portion of said object that is heated, and
- a heat treatment adjusting step of adjusting a heating time, as based on information of said temperature measured, and outputting a cooling start signal.
