Abstract: A new type waveform function of a steel continuous casting mold non-sinusoidal oscillation was constructed and a motor driven equipment scheme realizing the non-sinusoidal oscillation was put forward. The superiorities of the waveform function and the implementation scheme were analyzed. The reasonable value ranges of the parameter α(deviation rate compared with sinusoidal waveform) were discussed. The calculation methods of technological parameters were given, such as negative slide time, negative slide rate, negative slide distance, positive slide time, the maximum relative velocity between slab and mold. The isoplethic curves of multi-parameters were given, which provide a reference for the modeling oscillation synchronization control of casting velocity and oscillation frequency, and the applications of non-sinusoidal oscillation technique.

Key words: steel continuous casting mold, non-sinusoidal oscillation, waveform function, oscillation technological parameter
