Abstract
An induction heating device for heating a metal article includes a support plate with an upper surface for receiving the metal article, and a plurality of induction coils, which are arranged concentrically around an axis and are provided at an underside of the support plate. Each induction coil is connected to and selectively powered by a generator, and at least one temperature probe is disposeable on the metal article during heating in order to monitor and control the heating of the article.
Claims18
An induction heating device for heating a metal article, the device comprising:
- a support plate with an upper surface for receiving a side face of the metal article and an underside;
- a plurality of induction coils arranged concentrically about an axis and disposed beneath the underside of the support plate;
- an alternating current generator electrically connected with each one of the plurality of induction coils and configured to supply electric power to each induction coil;
- and a control unit electrically connected with the generator and configured to operate the generator to selectively power the induction coils, to determine the load on each one of the coils when each coil is being powered, and to estimate at least one dimensional characteristic of the metal article based on the load on each one of the coils;
- further comprising at least one temperature probe disposeable upon the metal article during heating in order to monitor and control the heating of the article.

- at least one temperature probe disposeable upon the metal article during heating in order to monitor and control the heating of the article;
- and a temperature indicator connected to the at least one temperature probe and configured to selectively display the temperature measured by the at least one temperature probe and to alternatively display a target temperature to which it is desired to heat the metal article;
- further comprising a control unit electrically connected with the generator and configured to operate the generator to selectively power the induction coils to heat the metal article to the target temperature.
