Abstract：In order to enhance the practicability of crystallizer hydraulic vibration system and extend the service life of the equipment, two new non-sinusoidal hydraulic vibration waveform mathematical models were established according to the actual operation of hydraulic vibration equipment, which were linear-sine composite and linear piecewise function (L-SLPF) and two linear-sine composite function (TL-SCF). Firstly, by setting different control parameters, the two new vibration waveforms were simulated by MATLAB. Then, combined with two commonly used non-sinusoidal vibration waveforms, these four waveforms were analyzed and compared from vibration parameters such as non-sinusoidal factor, max up-speed and max acceleration. The results show that the vibration waveforms new proposed are superior to other waveforms. The L-SLPF function has an unlimited value of non-sinusoidal factor, ranging from 0.5 to 0.7. The TL-SCF function accelerates continuously and smoothly and has minimal impact on equipment, which is more suitable for high frequency and high casting speed production. Therefore, the new vibration waveforms expand the application range of crystallizer hydraulic vibration system, which can be applied to the continuous casting machine with high vibration frequency and high casting speed, and are more friendly to the equipment and effectively extend the service life of the equipment.
