摘要： 针对国内某酸轧机组使用的卡罗塞尔卷取机出现的卷取错层问题,通过对卡罗塞尔卷取机卷取的受力分析,揭示了卷取错层的本质原因在于末架轧机到卷取机之间的带钢内部存在弯曲应力,分析了引起带钢内部弯曲应力的原因,通过机械和电气等方面采取相应的措施后,解决了卷取错层的问题.同时分析了大转盘转动过程中大转盘的角加速度与转角位置之间的定量关系,为提高大转盘转动过程中卷取张力动态控制的稳定性提供了理论依据和解决方案.

Abstract: How to solve the problem of disorderly strip wrapping on a Carrousel coiler used for a PL-TCM unit in China was investigated. The forces acted on the coiler in its coiling process was analyzed, thus revealing that the disorderly strip wrapping is essentially because of the internal bending stress of strip between the last mill stand and the coiler. Discussing the reason why the internal bending stress forms in strip, the problem of disorderly strip wrapping was solved via the mechanical measures taken appropriately. On the other hand, the quantitative relationship between the angular acceleration of the big rotating disc as a past of the coiler and its angular position during rotation was analyzed with the intention of providing theoretically the reference and solution to improve the stability of dynamic control of the coiling tension in the process of rotation of the big rotating disc.
