Abstract:
In order to adjust the modification ratio of non-sinusoidal oscillation waveform online, a new mechanical oscillator of continuous casting mold synchronous driven by double servomotors was proposed in this paper. Firstly, the rigid-flexible coupled model of oscillator was established. Secondly, the working principle of non-sinusoidal oscillator was analyzed and the model of the oscillator was validated by using dynamics software. Then the non-sinusoidal oscillation waveform function was given and the angular speed of the servomotor was deduced. Besides, by analyzing the parameters of oscillation technology, the calculation method of each oscillation technological parameter was presented, the multi technological parameters curves were given and the control model of casting speed and oscillation frequency was established. Compared with the industrial parameters of sinusoidal oscillation, the synchro-control model of non-sinusoidal oscillation could improve the slab quality. The results of this paper will provide reference for the oscillator optimization and industrial application.
