The method is used in this paper to study the influence of plate width on plate shape, and some varying rules of crown with plate width are discovered.
采用实验的方法对板宽对板形的影响进行了较为系统的研究，发现了板凸度随板宽变化的一些规律。

The application results show that work roll and backup roll designed with this method have good adaptability, and the platecrown and roll consumption have been reduced greatly.
The predicted models of platecrown, the prediction and feedback models of plate shape are set up on the basis of Ben Cheng's elastic deformation theory by simplifying and discretizing the models.
