Shape Rolling and Lateral Spread

该项目将研究板材轧制中的横向流动和横向扩展，以提高我们对传统板材轧制中发生的形状变化的理解。其目的是建立一个板形轧制的解析理论，该理论可以用来建立三维板材轧制的近似模型，该模型可以足够快地求解，以便用于轧钢厂的控制系统。尽管板材在工业上得到了广泛的应用，但要生产出高度均匀且缺陷最少的板材是非常困难的。为此，需要对轧制参数进行传感和控制。现有的分析技术太慢、太复杂，不能在正常的工业生产速度下使用。这项工作将开发一种简化但准确的分析模型，该模型可以有效地应用于高速轧制。

The project will investigate transverse flow and lateral spread in sheet rolling in order to improve our understanding of the shape changes that occur in conventional sheet rolling. The aim is to formulate an analytical theory for shape rolling which can be used to develop approximate models of three-dimensional sheet rolling that can be solved rapidly enough to be used in rolling mill control systems. Although sheet metal is widely used by industry, it is very difficult to produce highly uniform sheet metal with minimal defects. In order to do so, sensing and control of the rolling parameters is required. Existing analysis techniques are too slow and complex to be used at normal industrial production speeds. The work will develop a simplified but accurate analytical model which can be effective in high speed rolling.
