The main function of the mould oscillation deflection detection instrument is to detect the the mould oscillation table’s oscillation frequency, amplitude, deflection rate, phase, oscillation trajectory curve, etc. Through the detection and adjustment of the detection instrument, the mold moves along the outer arc of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics. The actual oscillation parameters of the mold oscillation table during the operation and production process and the process parameters of the cast products cannot be effectively known without the data detection of the mold deflection detection instrument, so that the operator cannot adjust the mould’s production process parameters in real time according to the real- time situation of the on-site production. The continuous casting mold deflection detection instrument independently developed by our company is suitable for various molds such as slab, square billet, round billet and shaped billet. The system obtains the process parameters such as actual oscillation holographic parameters and negative slip amount of the oscillation table by effectively detecting the movement of the mold.
