用新的摩擦模型研究板带轧机工作辊最大许用直径

An analysis of the maximum work roll permissible diameter using new friction model

带材最小厚度决定板带轧机工作辊最大许用直径，本文采用包括粘着摩擦和滑动摩擦的混合摩擦模型，得出了轧制力新模型，并以此建立了工作辊最大许用直径与极限可轧厚度和最小可轧厚度的关系式，用实测数据验证了本文的两个最大许用直径公式。

The lowest gauge of sheet and strip determines the maximum work roll permissible diameter. The relationship formulae of maximum work roll diameter and lowest rollable gauge and limit lowest gauge are obtained by using roll load model which is based on new combined friction model including stick friction zone and slip friction zone. The formulae are validated by using practical data.
