冷轧带材板形辊传动方案设计

 板形在线测控是提高冷轧带材板形质量的关键措施。不同轧机的板形检测辊结构和尺寸差别较大，传动方案有被动与主动两种。不合理的传动方案可能导致带材与检测辊之间发生打滑，划伤带材。为解决上述问题，首先阐述了主、被动方案的整体选择依据。然后提出了打滑安全系数的概念，分析了引起打滑的主要因素，并将打滑安全系数作为新增板形仪传动方案的选择依据。针对被动方案，提出了提高打滑安全系数的具体措施，针对主动方案，建立了具体的电机选型理论。最后通过两套工业应用的板形检测辊，分别对主、被动方案进行了验证。

Electric drive scheme design of flatness meter for cold rolling strip

The flatness measurement and control are the key technology to improve the flatness quality of the cold rolling strip. The structure and size of the flatness measurement rollers of different rolling mills are quite different，and the electric drive of the flatness meter may be active or passive. An unreasonable electric drive of the flatness meter may cause the slippage between strip and roller，which may scratch the strip. To solve the above problem，the overall selection criteria of active and passive schemes are elaborated firstly. Then，the concept of the skidding safety factor is put forward，and the main factors causing skidding are analyzed. The skidding safety factor is taken as the criterion for selecting the electric drive scheme of the new flatness meter. Aiming at the passive scheme，the specific measures for increasing skidding safety factor are put forward. Aiming at the active scheme，specific motor selection theory is established. Finally，different electric drive schemes are verified through two sets of industrial flatness measurement meter.
