- 摘要:
- 正弦与非正弦振动是目前连铸结晶器常用的振动形式。在新建或技术改造项目中,普遍提倡采用非正弦振动以提高铸坯质量、拉速。正弦与非正弦波形均具有振动所需的特征参数,针对这些工艺参数,具体分析了各工艺参数在正弦和非正弦工况下的变化趋势。结果表明,这更有利于更好的理解两种波形的特点,为实际生产参数的选择提供了参考。
At present,sinusoidal and non-sinusoidal oscillations are commonly used in continuous casting molds.Non-sinusoidal vibration is generally recommended to improve billet quality and drawing speed in new construction or technical transformation projects.Both sinusoidal and non-sinusoidal waveforms have characteristic parameters required for vibration.Aiming at these process parameters,the variation trend of each process parameter under sinusoidal and non-sinusoidal working conditions is analyzed in detail.The results show that this method is beneficial to better understand the characteristics of the two waveforms,and provides a reference for the selection of actual production parameters.
