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 steel plate and plate crown control, loaded roll gap shape determines the shape of the rolling rolls, only from the essence of the full research of rolling mill deformation, accurately predict the section distribution of certain technological conditions to the finished workpiece.
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。
Because the rolling process of high strength plate width plate is a very complicated metal forming process of plate shape and plate crown is affected by many factors, such as roller crown, roll eccentricity, roll wear inhomogeneity, the temperature difference of the 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。
Control method of high-strength steel plate is controlled by finishing steel plate flatness constant high-strength plate, low alloy plate to achieve constant 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.
汽車用先進高強度鋼板在減重，節能，提高安全性，降低排放等方面展現出廣闊的前景。國內鋼鐵企業應及時掌握國內外先進高強度汽車鋼板的發展動向，適時進行產品開發及應用技術的研究工作，使我國汽車用鋼達到世界先進水平。
Automotive advanced high strength steel plate in weight loss, energy saving, improve safety, reduce emissions and other aspects show a broad prospect. Domestic iron and steel enterprises should grasp the development trend of domestic and foreign advanced high strength automobile steel plate in a timely manner, timely carry out the research work of product development and application technology, so that the automobile steel in our country has reached the world advanced level.
