摘要
PROBLEM TO BE SOLVED: To provide a method for appropriately grasping an exchange period of a plate for stabilized operation by reliably and simply detecting a normal or abnormal condition of a slide valve at the time of maintaining a ladle or a tundish, and to provide a device therefor.;SOLUTION: The abnormality detecting device comprises a hydraulic unit 10 which drives a hydraulic cylinder 9, a pressure transmitter 12, a data collecting and processing device 13, an alarm 14, and a display device 15. The pressure transmitter 12 is fixed to a supply piping 11 for supplying a hydraulic fluid to the hydraulic cylinder 9 connected with a slide plate 1a of the slide valve 1 from the hydraulic unit 10. The sliding pressure PA of a detected slide plate 1a is captured by the data collecting and processing device 13 and compared with a predetermined sliding pressure. When the detected sliding pressure PA goes beyond the predetermined sliding pressure, abnormality is detected and outputted to the alarm 14. By this way, abnormality of the slide valve plate can surely be detected by the device with a simple structure.;COPYRIGHT: (C)2005,JPO&NCIPI
