Abstract：At the time of preventing the steel leaking, the non-sinusoidal Oscillation techniques can shorten the negative strip time and enhance the slab surface quality during steel continuous casting. But Non-sinusoidal vibration’s acceleration is higher than sine vibration, and it is easy to impact thus reduce the mold movement stability. To solve this problem, a new type of waveform function of the mold non-sinusoidal oscillation is constructed, in which the acceleration can be adjusted to the realistic situation to ensure the dynamic characteristics of the waveform function. For this waveform function, in the case of constant acceleration, the enlargement of the waveform deviation factor results in the shortness of negative strip time. The character of non-sinusoidal oscillation can be enlarged without affecting the movement smoothness of mold. Moreover, in the case of the constant waveform deviation factor, the shorter negative strip time makes the acceleration smaller. So at the time of enlarging the mold movement smoothness, the slab surface quality can be enhanced. By analyzing the parameters of oscillation technology, the calculation method of each oscillation technological parameter is presented, the multi-technological-parameter curves are given and provides reference for establishing the control model of casting speed and oscillation frequency.
