Abstract
A manufacturing method for a continuously cast product of steel includes the steps of detecting a position of a crater end of the product by measuring a solidification state of the continuously cast product using a sensor which is not a 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 the crater end. The method for measuring a solidification state of the continuously cast product includes the steps of cooling the product until the surface layer portion is α transformed, transmitting transverse waves of electromagnetic ultrasonic waves to the colled product as a transmitting signal, receiving a signal after said transmitting signal propagates in said product as a receiving signal, and judging the solidification state of said product based on the receiving signal.
