A New Non-Sinusoidal Oscillation Waveform for Continuous Casting Mold

Abstract:

A new non-sinusoidal oscillation waveform which is shown by waveform distortional rate was advanced. The amplitude, oscillation frequency, waveform distortional rate and casting velocity were established for a computer model of the continuous casting process. The range of waveform distortional rate was ascertained. The choosing method of amplitude and oscillation frequency was given. These offered a theory basis to the application of the advanced technique. Industrial scale experiments showed the new type waveform is effective on improving the quality of continuous casting slab and reducing breakout.
