摘要: 针对我国某钢厂高速冷连轧机组冷连轧机组轧制T5极薄带材时,第5机架轧制速度超过650 m/min出现轧机振动的问题,从生产现场该机组轧机振动的实测分析入手,确定了该轧机的振动源和振动频率,并采用有限元动态分析计算,验证了轧机振动实测分析结果和振动形态。根据实测分析和有限元计算所确定的振动轧机辊缝润滑油膜变化而引起轧机振动的结论,通过优化该轧机的轧制润滑工艺,有效抑制了该机组轧制T5极薄带材时出现轧机振动的现象,使该机组的轧制速度从650 m/min左右提高到900 m/min以上,消除了该机组轧制T5极薄带材的瓶颈问题。

Abstract: Dealing with the vibration behavior in the 5th mill with the rolling seed over 650 m/min for T5 strip continuous cold rolling in one of the steel enterprises of China, starting with the measurement and analysis of the mill vibration, the vibration source and frequency are confirmed, and the measured results and the patterns of the vibration are verified by FEM. According to the conclusion that the vibration is caused by the lubricant state in the roll’s gap, with optimizing the lubricating state of the mill, the vibration behavior is eliminated while rolling the T5 strip with the rolling speed to/over 900m/min, the mill’s bottle-neck problem for T5 strip rolling is overcome.

Key words: cold-rolling mill, lubrication, rolling, steel strip, vibration
