Abstract
A manufacturing method for a continuously cast product of steel includes the steps of detecting a position of crater end of product by a method for measuring a solidification state of continuously cast product using a sensor arranged so as to be in non-contact with the product, and controlling at least one condition selected from the conditions of the casting speed and the quantity of secondary cooling water based on the detected position of crater end. The method for measuring a solidification state of continuously cast product includes the steps of cooling the product until a surface layer portion thereof is α transformed, transmitting transverse waves of electromagnetic ultrasonic waves to the cooled product, receiving the signal after the transmitting signal propagates in the product, and judging the solidification state of the product based on the received signal.
