摘要： The present invention is intended to adjust an amount of thermal expansion at a desired position in an axial direction of a roller body of an induction heated roll apparatus, regardless of an amount of load heat extracted from the roller body by a heating target object. The induction heated roll apparatus includes the roller body that is cylindrical and has a hollow space, a plurality of induction coils provided in an inside along the axial direction of the roller body, a power supply circuit that controls power supplied to each of the plurality of induction coils individually, and a cooling mechanism that cools the roller body by supplying a refrigerant to the roller body.

摘要： A coaxially arranged smart susceptor conductor, comprising a smart susceptor core comprising an alloy having a first Curie temperature point and a first smart susceptor shell coaxially arranged around the smart susceptor core. The first smart susceptor shell comprising a second Curie temperature point that is different than the first Curie temperature point of the smart susceptor core. In one arrangement, the second Curie temperature point of the first smart susceptor shell is lower than the first Curie temperature point of the smart susceptor core. In another arrangement, the smart susceptor conductor further comprises a second smart susceptor shell disposed about the first smart susceptor shell. The second smart susceptor shell comprising a third Curie temperature point.

摘要： Inductive heating systems and method of controlling the same to reduce biological carryover are disclosed herein. An example system includes an induction heater including a tank circuit, the tank circuit including a work coil and a sense coil. The sense coil is to detect a magnetic field generated by the work coil and to output signals in response to the detection. The example system includes a controller to cause the tank circuit to oscillate at a resonant frequency in response to the signals and a power drive unit in communication with the controller and the induction heater. The power drive unit is to adjust power provided to the induction heater in response to the controller driving the tank circuit to oscillate at the resonant frequency.

摘要： The hand-held induction air-cooled induction heater used for heating of metallic mechanical or decorative objects to facilitate their removal or installation contains a high frequency inverter operating in voltage or current resonant mode, including power semiconductor switching device(s) having turn-on or turn-off delay time, circuitry to control the timing of on and off periods of said switching device(s), the circuitry having delay time, wherein the threshold voltage or current reference to initiate commutation or timing is not zero, and is dynamically varied in response to the instantaneous input inverter supply voltage and/or inverter frequency to achieve switching device(s) heating or dissipation reduction resulting from improved commutation timing of said power switching devices.

摘要： A solenoidal induction coil with dynamically variable coil geometry is provided for inductively welding or heating continuous or discontinuous workpieces passing through the solenoidal induction coil in a process line. The coil geometry can change, for example, as the outer dimension of the workpiece passing through the solenoidal induction coil changes or as non-continuous workpieces pass through the solenoidal induction coil in an induction heating or welding process line.
