roll (or mill) number

The method uses technique of scalping the false points, filtering and tendency smoothing, to pretreat original roll eccentricity signal, and then to analyze the pretreated signal by modified fast Fourier transform, thus the resolution rate of spectrum can be increased.

针对目前冷轧生产中因轧辊偏心引起带材厚度波动的问题,提出了一种提高轧辊偏心信号频谱分析精度的方法。

Cr3 steel rollers are widely used presently;the local welding repair has important significance.

研究了不同预热温度和焊后缓冷对Cr3钢轧辊局部堆焊修复质量的影响。
