The invention discloses a waveform adjustable non-sinusoidal vibration method of a continuous casting crystallizer, which belongs to the technical field of continuous casting. The method is characterized in that a drive device for controlling the continuous casting crystallizer drives the continuous casting crystallizer, in every vibration period, to conduct non-sinusoidal vibration according to a track determined by the following vibration displacement procedure function: a formula (1) is as described in the specification, wherein S(t) is the displacement of the non-sinusoidal vibration; h is the stroke of the non-sinusoidal vibration; omega is angular velocity of the non-sinusoidal vibration, t is time of the non-sinusoidal vibration, ai is a technology constant correlated to the sinusoidal vibration and is not correlated to the stroke h and the angular velocity omega; and i is a term number. According to the method, when the track determined by the vibration displacement procedure function in a quadrinomial can ensure that the waveform does not distort when the rate of deflection is 0-37.5%; and the velocity, accelerated velocity and accelerated velocity change of the non-sinusoidal vibration of the crystallizer are all monotonous and continuous, so that the impact on equipment due to flutter in the course of operating is avoided, and the operation of the equipment is more stable and reliable.
