轧机振动特性及影响因素

Key Points

• This research aims to explore the vibration characteristics of rolling mills and identify the influencing factors affecting product quality and process stability.
• Analyzed vibration types including vertical, horizontal, and torsional vibrations.
• Investigated the impact of parameters such as rolling speed, reduction amount, and lubrication conditions.
• Vertical vibrations are associated with roller system fluctuations and steel thickness variability.
• High rolling speeds and poor lubrication are identified as primary causes of self-excited vibrations.
• Low-frequency vibrations (<100Hz) arise from mechanical resonance, while mid-high frequencies (100-1000Hz) result from dynamic loads.
