The hydraulic vibration table is an important equipment of the modern slab continuous casting machine. It can easily set and change the waveform, amplitude, and frequency, and can achieve non-sinusoidal vibration, which can greatly meet the needs of the slab continuous casting process. The vibration table servo valve is always in a high-frequency and large-stroke state. Its movement is prone to wear and tear, resulting in zero-position leakage, which leads to increased zero-position current and jitter at the peak of the vibration curve. When in a high-temperature environment, poor cooling can easily cause the position sensor system to lose control and generate disordered signals. When the accumulator bladder is damaged, the vibration and noise of the pipeline increase. Keywords: continuous casting; vibration; fault; diagnosis
