ABSTRACT:
Apparatus for continuous casting has pairs of rolls defining a path for the solidifying slab of steel. Between the rolls on each side are rows of spray nozzles. To check the operation of the sprays and thus achieve uniform cooling, checking apparatus carrying detectors for the sprayed water is passed through the path. To achieve a useful measure of the spraying efficiency the detectors must be highly sensitive and robust. Each detector has a metal diaphragm which is set in vibration by the sprayed water and a piezo-electric element fixed to the diaphragm so as to emit a signal whose amplitude is dependent on the amplitude of the vibration of the diaphragm.
