高強板的板形的影響因素是高強板，低合金板板形控制研究的關鍵。輥縫控制的核心是高強板板型以及板面凸度的控制，承載輥縫的形狀決定了軋件的斷面形狀，只有從本質上充分地研究軋機的輥系變形，才能準確地預測一定工藝條件下的軋件成品的斷面分布。

The influence factors of high strength plate shape are the key of high strength plate and low alloy plate shape control. Roll gap control is the core of high strength slab and plate convexity control, carrying the shape of roll gap determines the section shape of the workpiece, only from nature full of mill roll system deformation to accurately prediction profile distribution under the condition of rolling products.

由于高強板等寬厚板的軋制過程是一個非常復雜的金屬形成過程，板形、板凸度受多種因素的影響，如軋輥原始凸度、軋輥偏心、軋輥磨損的不均勻性、軋件的溫度差彎輥力等等。

Due to high strength plate width thick plate rolling process is a very complicated metal forming processes, plate shape and plate crown by the influence of many factors, such as the primordial crown of roller, roller eccentricity, roll wear is not uniform, workpiece temperature difference and bending force and so on.

高強板板型的控制方法是通過控制精軋道次的鋼板板面平整度來恒定高強板，低合金板的恒定原則實現。高強板，低合金板在生產中利用上道次板厚、板凸度及平直度的實際測量值，修正更為合適的彎輥力，實施板形的最優控制。

High strength plate flatness control method is through control finishing steel plate flatness constant high strength plate, low alloy plate, the invariance principle. In the production of high strength plate, the low alloy plate is used to measure the thickness of the plate, the convexity of the plate and the flatness of the plate. The correction is more suitable for the bending roll force, and the optimal control of the shape of the plate is implemented.
