摘要： There is provided an induction heating apparatus which continuously heats a steel plate using a solenoid system. The induction heating apparatus (1) includes: at least three heating coils (10A to 10D) disposed along a longitudinal direction of the steel plate to make the steel plate (2) pass through an inside thereof; and inductance adjusters (12A to 12D) disposed on electrical pathways (11) electrically connecting each of the heating coils and a power source applying a voltage to each of the heating coils and capable of generating self-induction and adjusting self-inductance in the self-induction, in which each of the inductance adjusters is disposed to cause a generation of mutual induction at least between the inductance adjusters mutually adjacent to one another.

摘要： A continuous casting apparatus for steel includes: a casting mold for casting a molten steel with a pair of long side walls and a pair of short side walls; a submerged entry nozzle which discharges the molten steel into the casting mold; and an electromagnetic stirring device which is disposed along each external surface of each of the long side walls and stirs an upper portion of the molten steel within the casting mold. A curved portion which is convexly curved toward the electromagnetic stirring device in plan view is formed at least at a position where the curved portion faces the submerged entry nozzle on each of the long side walls, and each of the long side walls including the curved portion has a uniform thickness. The shortest horizontal distance between a top which is a most depressed position when an internal surface of the curved portion is seen in plan view and an outer peripheral surface of the submerged entry nozzle is 30 mm to 80 mm in a range from a lower end portion of the electromagnetic stirring device to a position higher than an upper end portion thereof by 50 mm when viewed along a vertical direction.

摘要： A control unit of an induction heating unit controls AC power output to a heating coil of a transverse type induction heating unit that allows an alternating magnetic field to intersect a sheet surface of a conductive sheet that is being conveyed to inductively heat the conductive sheet. The control unit includes: a magnetic energy recovery switch that outputs AC power to the heating coil; a frequency setting unit that sets an output frequency in response to at least one of the relative permeability, resistivity, and sheet thickness of the conductive sheet; and a gate control unit that controls a switching operation of the magnetic energy recovery switch on the basis of the output frequency set by the frequency setting unit.
