Title:
DIAGNOSTIC DEVICE FOR COOLING WATER SPRAYING CONDITION OF WATER COOLING NOZZLE
Document Type and Number:
Japanese Patent JP2607340
Kind Code:
B2
Abstract:
PURPOSE: To precisely diagnose the normal/defective condition of spraying cooling water for cooling hot rolled steel by housing a pressure sensor in a housing box, receiving cooling water sprayed from a water cooling nozzle by a pressure receiving plate installed outside the housing box and also making the pressure receiving surface of the pressure receiving plate wider than the upper surface of the pressure sensor.
CONSTITUTION: A carrier plate 1 to be passed through a water cooling zone of cooling water sprayed from plural water cooling nozzles is conveyed by a conveying roller for conveying a hot rolled plate material. In a housing box 2a which is mounted on the carrier plate 1 and vertically movably supports a vertical bar 2h for transmitting acting force is housed a sensor 2b for outputting an electric output signal corresponding to the pressurizing force based on the lowering of an elastic body 2f for pushing up the transmitting bar 2h and the transmitting bar 2h. And a pressure receiving plate 2g having a pressure receiving surface wider than the upper surface of the sensor 2b for receiving cooling water sprayed from the water cooling nozzles is fixed to the upper end of the transmitting bar 2h. And an output signal from the sensor 2b is inputted to a signal treatment device, where the output signal is treated.
