Shape Rolling and Lateral Spread

该项目将研究板轧制中的横向流动和横向扩展，以提高我们对传统板轧制中发生的形状变化的理解。目的是建立一种异形轧制的解析理论，该理论可用于建立三维薄板轧制的近似模型，该模型可以快速求解以用于轧机控制系统。虽然钣金在工业上得到了广泛的应用，但要生产出具有最小缺陷的高度均匀的钣金是非常困难的。为了做到这一点，需要对轧制参数进行传感和控制。现有的分析技术过于缓慢和复杂，无法在正常的工业生产速度下使用。该工作将建立一个简化而准确的分析模型，可以有效地用于高速轧制。

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.
