川崎钢铁公司改进的轧辊超声波探伤仪,已在千叶钢铁厂和水岛钢铁厂采用。主要通过提高超声波的振动控制技术,提高了检出精度,对过去可检出缺陷仅1/3的小缺陷亦可检妯,从而十分有利于提高轧辊使用寿命。因此,两厂每年可降低成本1亿日元。对轧辊上探伤装置上附加的测头的检出器改 Kawasaki Steel's improved roll ultrasonic flaw detector has been adopted at Chiba Steel Works and Mizushima Steel Works. Mainly by improving the ultrasonic vibration control technology to improve the detection accuracy of the past can detect defects only 1/3 of small defects can be seized, which is very conducive to improving the service life of the roll. Therefore, the two plants can reduce the cost of 100 million yen per year. Probe on the testing device attached to the probe on the detector change
