| titleOfInvention | Iron loss value evaluation method and apparatus |
| abstract | (57) [Summary] [PROBLEMS] To accurately measure the sound velocity of plate wave ultrasonic waves propagated to evaluate iron loss of a steel sheet having a large iron loss value such as a grain-oriented electrical steel sheet. SOLUTION: An ultrasonic transmitter T disposed on the surface of a steel plate, an ultrasonic pulser 11 for generating a pulse for transmitting a plate ultrasonic wave from the transmitter T, and a propagation direction of the plate ultrasonic. And two or more receivers R1 and R2 that are arranged at a predetermined distance apart along the plane and detect plate wave ultrasonic waves propagating through the steel plate as electric signals, and signals received by the receivers R1 and R2, respectively. A cross-correlation calculation circuit 14 for calculating a cross-correlation calculation value between the two, and measuring the sound velocity of the plate-wave ultrasonic wave from the cross-correlation calculation value and the separation distance between the receivers R1 and R2, The system controller 10 calculates the iron loss value of the steel sheet from the sound speed or the propagation time obtained from the sound speed based on the relationship between the sound speed of the steel sheet and the iron loss value of the steel sheet or the relationship between the propagation time of the plate wave ultrasonic wave and the iron loss value of the steel sheet.
