摘要

各种特性的钢铁产品的发展,增加了对生产机械进行及时、预防性维护和状态监测的需求。例如,现代钢铁厂的轧辊矫直机,由于矫直的钢材范围很大,因此受到的力变化很大。本文对冷轧带钢矫直机的振动进行了分析,以确定不同的操作条件对振动的影响。从振动信号中计算出广义范数、广义范数和和波峰因子等特征。分析了带钢性能和机器运行参数对这些特性的影响。所获得的信息可用于模型中,作为矫直机预防性维修的规划工具。

The Effect of Steel Leveler Parameters on Vibration Feature
The development of steel products with various characteristics increases the need for timely and preventive maintenance and condition monitoring of the production machinery. For instance, the roller levelers at modern steel factories are exposed to a high variation of forces due to the large range of steels leveled. In this study, the vibration measured from a steel leveler used for cold steel strips is analyzed with the goal to identify the effects different operational conditions have. Features such as generalized norms, generalized norm sums and the crest factor are computed from the vibration signals. The effects of the steel strip properties and the operational parameters of the machine on these features are then analyzed. The obtained information can be utilized in the models that are used as planning tools for the preventive maintenance of the steel leveler.
