Abstract
The invention discloses a string sound beam compression scanning imaging method for rapidly detecting cracking of a thick plate roller. An incidence point and a receiving point of ultrasonic waves are arranged on the outer surface of the thick plate roller; an ultrasonic transmitting sensor and an ultrasonic receiving sensor are correspondingly arranged at the incidence point and the receiving point, and ultrasonic signals are received and transmitted on the outer surface of the thick plate roller, so that a string-shaped acoustic beam straight line is formed in a roller body of the thick plate roller, and a fluctuation path of ultrasonic waves is projected on the cross section of the thick plate roller to form the acoustic beam straight line. And the internal flaw detection of the thick plate roller is realized. The method is specially used for effectively detecting the radial cracks in the thick plate roller, flaw detection is carried out on the thick plate roller in a non-leak-detection mode, a rapid and simple technical means is provided for avoiding sudden failure fracture, and production risks are controlled in time.
