This application discloses a method, device, and medium for controlling fluctuations in the liquid level of a slab continuous casting machine's crystallizer, relating to the field of process flow. The method involves real-time analysis of the liquid level signal acquired by the liquid level control system using Fourier transform. The frequency of periodic fluctuations in the crystallizer liquid level is compared, and the relationship between the corresponding amplitude and a preset amplitude is obtained through a spectrum diagram. This allows for timely adjustment of the liquid core space to suppress fluctuations. In the early stages of periodic fluctuations in the crystallizer liquid level, specific changes in fluctuation data are detected at the microscopic level, enabling advance prediction of specific spectral signs before fluctuations occur. Compared to existing systems that require complex control systems and associated control models for adjustments during periodic fluctuations, resulting in higher maintenance costs and greater accuracy variations, this method allows for corresponding compensation control processing in the early stages of fluctuations. This prevents late compensation from leading to excessively large amplitudes that are difficult to suppress, reducing maintenance costs and extending equipment lifespan.
