高强板的板形的影响因素是高强板,低合金板板形控制研究的关键。辊缝控制的核心是高强板板型以及板面凸度的控制,承载辊缝的形状决定了轧件的断面形状,只有从本质上充分地研究轧机的辊系变形,才能准确地预测一定工艺条件下的轧件成品的断面分布。
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.
由于高强板等宽厚板的轧制过程是一个非常复杂的金属形成过程,板形、板凸度受多种因素的影响,如轧辊原始凸度、轧辊偏心、轧辊磨损的不均匀性、轧件的温度差弯辊力等等。
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.
高强板板型的控制方法是通过控制精轧道次的钢板板面平整度来恒定高强板,低合金板的恒定原则实现。高强板,低合金板在生产中利用上道次板厚、板凸度及平直度的实际测量值,修正更为合适的弯辊力,实施板形的最优控制。
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.
