发布时间：2018-11-22 15:03
【摘要】：为了实现变厚度过渡区轧制形状尺寸的精确控制,本文提出了四种类型过渡区,并建立了四种类型过渡区曲线的数学模型,分析了差厚板过渡区轧制中轧辊中心运动轨迹,建立了过渡区轧制轧件出口水平速度与轧辊垂直压下速度的匹配关系。带有直线主导型过渡区的差厚板应用于上汽集团汽车仪表板横梁钢管的制作,取得了良好的减重效果。按照本文给出的理论与方法控制过渡区厚度,其实测厚度结果与设定值符合很好,其最大偏差为0.056 mm,偏差标准差为0.014 mm。研究结果对加快国产差厚板在汽车轻量化中应用提供了参考。
[Abstract]:In order to accurately control the shape and size of rolling in the transition zone with variable thickness, this paper presents four types of transition zones, establishes the mathematical models of the curves of the four types of transition zones, and analyzes the motion track of the roll center in the rolling process of the transition zone of the different thickness plate. The matching relationship between the horizontal velocity at the outlet of rolling piece and the vertical rolling speed in the transition zone is established. The differential thick plate with linear leading transition zone is used in the manufacture of SAIC automobile dashboard steel pipe, and good weight reduction effect is obtained. According to the theory and method given in this paper, the thickness of transition zone is controlled. In fact, the measured thickness is in good agreement with the set value, and the maximum deviation is 0.056 mm, and the standard deviation is 0.014 mm.. The results provide a reference for speeding up the application of domestic differential thickness plate in automobile lightweight.
