【摘要】 热连轧机精轧机组的振动问题是引起板带厚差与表面振纹等产品质量问题的主要原因,也是造成轧辊频繁更换与零部件疲劳破坏的根源,不同的轧件规格和轧制工艺直接影响振动的剧烈程度,尤其是生产高强度薄规格产品时振动问题更为突出,甚至会导致轧制失稳而危害系统运行安全。本文针对某热轧机组现场出现的典型振动现象并结合实际生产工艺,讨论上下辊面非对称工艺条件工艺参数对振动问题的影响机理与规律,为提出抑制振动的工艺措施提供依据。更多还原

【Abstract】 The vibration of hot tandem rolling mill is the main cause for thickness fluctuation and marks on the rolling strip surface. It also leads to roll changing and fatigue of parts. The rolling schedule and process directly affect the vibration degree. The rolling mill is more easily to oscillate violently when the rolled strip is thin. It even causes the destabilization of rolling mill and unsafe operation. For the typical vibration phenomenon in hot tandem rolling mill, we studied the effects of asymmetric rolling process parameters on the vibration mechanism, so that the vibration suppress strategies can be put forward finally.更多还原
