【摘要】 以转炉化渣噪声的功率谱作为研究对象,发现了多特征频带现象,并通过整个过程的功率谱确定了各特征频带的分布。计算出各特征频带的功率谱,并经过线性组合得到反映化渣状态的特征值,以图形方式向操作人员显示。更多还原

【Abstract】 Power spectrum of slagging noise in converter was studied, and then multi-eigenfrequency band was found. The distribution of eigenfrequency bands was gotten by the power spectrum in whole process. So the power spectrums were calculated for all eigenfrequency bands respectively, and then they were linearly combined to eigenfunction which could describe the status of slagging. Finally, the eigenfunction is showed in the visual mode for the operators.更多还原
