    摘要: The present invention uniformly cools a roll body and/or an induction heating mechanism by gas without complicating the configuration around the roll body. An induction heated roll apparatus includes a roll body having a hollow part, an induction heating mechanism disposed in the hollow part to subject the roll body to induction heating, and a cooling mechanism to cool the roll body and/or the induction heating mechanism by generating a gas flow in a clearance between the roll body and the induction heating mechanism. The cooling mechanism includes a suction port disposed on one axial end side of the roll body that communicates with the clearance, an exhaust port disposed on an opposite axial end side of the roll body that communicates with the clearance, and a suction mechanism coupled to the exhaust port that sucks the gas in the clearance from the exhaust port.

    摘要: The present invention is intended to prevent lifetime degradation of a conductor tube by reducing heat deterioration at output ports of the conductor tube. A superheated steam generator generates superheated steam by heating steam flowing through a spirally wound cylindrical conductor tube. The conductor tube is axially short-circuited and subjected to induction heating by a magnetic flux generation mechanism disposed on one or both of inner and outer sides of the conductor tube. Output ports of the conductor tube are disposed at axial midportions of the conductor tube.
