Abstract:
An apparatus and a method for ultrasonic detection are provided. The apparatus includes an injection nozzle which is installed below a steel plate being transported and forms a medium column by jet a medium toward the steel plate, an ultrasonic probe which is installed in the injection nozzle and transmits and receives ultrasonic waves for detecting flaws in the steel plate through the medium column, and a medium circulation unit which reclaims the medium which falls from the medium column and circulates the reclaimed medium to the injection nozzle.
