Moc-n300 Mold vibration testing device

Overview A mold is a device that forms a cast product in the continuous casting of steel, and is also the main equipment and key technology of a continuous casting machine. The main function of the mold vibration deviation detection device is to detect table vibration frequency, amplitude, deviation speed, phase, vibration path curve, etc. By detecting and adjusting the detection device, the mold moves along the outer surface. arc of a continuous casting machine in accordance with the specified amplitude, frequency and shape-generating deflection characteristics. The actual vibration parameters of the mold vibration table during the production process and the process parameters of the castings cannot be effectively known without the data detection of the mold deviation detection device, so the operator cannot adjust the mold production process parameters in real time. according to the production situation on site in real time. The continuous casting mold deviation detection device independently developed by our company is suitable for various shapes such as slabs, square, round and shaped billets. The system obtains process parameters such as the actual holographic oscillation parameters and the amount of negative slip of the oscillating table by effectively detecting the motion of the mold. Technicians can formulate a mold control strategy according to these actual parameters and improve the productivity and product quality within a safe and reliable range. Instrument Structure The continuous casting mold vibration and deviation detection instrument is mainly composed of a sensor system, a sensor signal conditioning circuit, a power supply circuit, a synchronous data acquisition module, a communication cable, and a software data analysis system. The device is equipped with three axial acceleration sensors to detect vibration and shape deviations, one of which is designed to detect the vertical vibration signal (Y-axis), and the other two are designed to detect the horizontal vibration signal (X and Z axis). The signal received by the sensor is processed by a preprocessor and a preprocessing module. The vibration signal and sensor status signal will be filtered and normalized, sent to the synchronous data collector for digitization and feature extraction, and the data is analyzed and processed by the host computer software to obtain various vibration parameters and process parameters required by users.
