【 摘 要 】

To improve the surface quality and casting speed of the slab further, a new type mold oscillator synchronously driven by double servomotors was proposed in this paper. The experimental prototype was designed and manufactured. For the non-sinusoidal oscillator, the waveform modification ratio could be adjusted during the steel continuous casing operation. Firstly, the working principle of the oscillator was described. Secondly, the rotating rules of the servomotor to realize non-sinusoidal oscillation waveform for entire function were given. Finally, the laboratory experiments were made. The experiment results show that the error of the two-side oscillation curves is smaller and the actual technological parameters are close to the theory and the oscillator can realize non-sinusoidal oscillation well. This kind of non-sinusoidal oscillator provides a feasible scheme for reducing oscillator investment, increasing casting speed and enhancing slab quality.
