titleOfInvention | Method for measuring physical properties of casting and ultrasonic measuring device |
abstract | (57) [Abstract] [Purpose] To realize a physical property measuring method for castings and an ultrasonic measuring device which are nondestructive, simple, and highly accurate and capable of measuring and calculating physical property values relating to an object to be cast. [Structure] Predetermined (V / Vm) -S conversion formula 530 Has a versatility, which is obtained by measuring the sound speed of a casting and the sound speed of a steel material, and is obtained from the correlation between this sound speed ratio and the directly measured spheroidization ratio of graphite. The spheroidization rate of the graphite of the cast specimen is measured in Mode 1 by measuring the sound velocity of the steel material (V m), the sound velocity (V) of the subject is measured in mode 2. Then, according to the conversion formula 530, these sound velocity ratios ((V / Vm)) to calculate the spheroidization rate of graphite. This allows Variations depending on the device and the measurer are reduced. |
