摘要： 针对国内中厚板轧机普遍存在的头部弯曲问题,通过对轧制过程进行分析,得出轧件上下表面温差和上下辊辊径比对轧件头部弯曲的影响规律,建立轧件头部弯曲曲率、轧机上下辊辊径比和轧件上下表面温差之间的关系模型.利用该模型可以根据轧制参数预测轧件弯曲曲率,为现场配辊提供理论依据.提出一种采用CCD摄像机测量轧件弯曲曲率的测量方法.

Abstract: Head warping is very common during plate rolling. Analyzing the plate rolling process, the problem of how the temperature difference between the top and bottom surface of a plate workpiece and the diameter ratio of upper roll to lower roll after the head warping of workpiece is investigated. A model is developed revealing the relationship between the curvature of head warping, the diameter ratio of upper roll to lower roll and temperature difference between top and bottom surfaces of workpiece. According to rolling parameters, the model can be used to predict the warping curvature, thus providing theoretically reference for proper roll matching. In addition, a measuring method is proposed for head warping curvature by CCD camera.
