  • Publication number: 20240167117
    Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.

  • Patent number: 11056262
    Abstract: The present disclosure provides an inductive element capable of lowering a Q-value. An inductive element includes a first cover and a second cover covering an annular core, and a first winding and a second winding wound around a region of the core, the first cover and the second cover. The first cover covers a part of an inner circumferential surface of the core, a part of an outer circumferential surface and an end surface on one end side in an axial direction. The second cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface an end surface on the other end side in the axial direction.
