Abstract: An ultrasonic inspection system is used to inspect grinding wheels used to prepare work rolls used in metal sheet production. The grinding wheel inspection system includes a test stand adapted to rotatably support a grinding wheel. An ultrasonic transmitting and receiving apparatus passes sound waves through the body of the grinding wheel. The attenuation of the sound waves passed through the grinding wheel is recorded in a recording device and analyzed in a computer. The recording device, which may be the computer, preferably records amplitude attenuation of the sound waves. The computer analyzes the amplitude attenuation, records the amplitude attenuation as an indicated density profile, and displays the indicated density profile on a computer screen for inspection. The indicated density profile of the inspected grinding wheel may be compared with indicated density profiles of other grinding wheels, particularly those with known operational characteristics.

Abstract: An ultrasonic inspection system (10) is used to inspect grinding wheels used to prepare work rolls used in metal sheet production. The ultrasonic inspection system (10) includes a test stand (12) adapted to rotatably support a grinding wheel (14). An ultrasonic transmitting and receiving apparatus (20) passes sound waves through the body of the grinding wheel. The attenuation of the sound waves passed through the grinding wheel (14) is recorded in a recording device (38) and analyzed in a computer (34). The recording device (38), which may be the computer (34), preferably records amplitude attenuation of the sound waves. The computer (34) analyzes the amplitude attenuation, records the amplitude attenuation as an indicated density profile (40), and displays the indicated density profile (40) on a computer screen (36) for inspection. The indicated density profile (40) of the inspected grinding wheel may be compared with indicated density profiles of other grinding wheels, particularly those with known operational characteristics.

Abstract translation: 超声波检测系统（10）用于检查用于制备用于金属板生产的工作辊的磨轮。 超声波检查系统（10）包括适于可旋转地支撑研磨轮（14）的测试台（12）。 超声波发射和接收装置（20）使声波穿过砂轮的主体。 通过磨轮（14）的声波的衰减被记录在记录装置（38）中并在计算机（34）中分析。 可以是计算机（34）的记录装置（38）优选地记录声波的振幅衰减。 计算机（34）分析幅度衰减，将幅度衰减记录为指示的密度分布（40），并将指示的密度分布（40）显示在计算机屏幕（36）上以供检查。 检查的砂轮的指示密度分布图（40）可以与其他砂轮的指定密度分布图进行比较，特别是具有已知操作特性的那些。
