摘要 |
PROBLEM TO BE SOLVED: To provide a cast piece shape measurement device capable of measuring the shape of a cast piece underneath a mold without causing trouble due to burnout of an ultrasonic probe in a continuous casting facility and also of easily performing an automatic correction every finishing of casting or in an optional timing without involving any dangerous operation. SOLUTION: A water cooled box 2 for housing an ultrasonic probe 3 has an ultrasonic radiation opening 20 at the edge of a water column nozzle 2a, and a shutter 7 double as a correction target for opening or closing the ultrasonic radiation opening 20 is provided at its tip. In the water cooled box 2, a water supply opening 22 is formed and it is connected to a water supply tube 9 through which water for cooling both ultrasonic wave transmission medium and ultrasonic probe 3 is supplied. On the midway of the ultrasonic radiation opening 20, a drain opening 21 is formed and a drain tube 8 having a pressure release valve 80 is connected thereto.
