摘要： A method and system are disclosed for treating a press hardened part by induction heating localized areas of the part to have reduced hardness. The method and system monitor an ambient temperature, cycle time, outgoing part property requirements, and outgoing part hardness in local areas. A time value and temperature value are set by a computer system for a plurality of induction heaters. A local area of the part is induction heated to soften the part in localized areas. The hardness of the localized areas is tested after induction heating.

摘要： The present invention for eliminating a need for a temperature detecting element adapted to measure the temperature of a roll main body provides an induction heated roll apparatus including: a roll main body; a magnetic flux generating mechanism including an iron core and a winding; and a power supply circuit provided with a control element adapted to control AC current or AC voltage. The apparatus calculates the temperature of the roll main body using an AC current value obtained by an AC current detecting part, an AC voltage value obtained by an AC voltage detecting part, a power factor obtained by a power factor detecting part, a winding resistance value of the winding, and an excitation resistance obtained from characteristics of a relationship between a magnetic flux density and an excitation resistance of a magnetic circuit including the iron core and the roll main body as parameters.

摘要： An induction heating device comprising at least one induction coil mounted to a support frame. The support frame is adapted to travel on a surface of an annular metal article to be heated and comprises a wheel set having one or more driven wheels. The support frame is adapted to travel on a side face of the annular metal article and is provided with first guide and second guide elements, which are respectively configured to engage with an outer circumferential surface and an inner circumferential surface of the annular metal article to ensure that the support frame travels on a circular path during use of the device.

摘要： One embodiment of a heated nozzle for extruding meltable material consists of an electrically conductive nozzle, comprised of an inlet, an outlet, and a passage connecting inlet and outlet. The nozzle fits into a hole or gap cut or formed through a loop of high permeability soft magnetic material such as ferrite or pressed iron powder. Electrically conductive wire is coiled around and through this magnetic loop to form a coil. A high-frequency alternating current is supplied to the coil, inducing a magnetic field in the magnetic core. The magnetic field, when passing through the electrically conductive nozzle, induces eddy currents that heat the nozzle to melt the material entering the inlet.
