The objectives of this study were to analyze the width changes about the head and tail ends of the slab occurring during vertical–horizontal rolling using finite element (FE) analysis, and to derive an appropriate short stroke control (SSC) model for vertical–horizontal rolling based on the results of analyses. The relationship between the process variables and slab deformation about the head and tail ends, including width shrinkage and length of width shrinkage, was derived using the linear regression method. From considering the amount of slab deformation, an advanced SSC model for vertical–horizontal rolling process has been developed. The proposed SSC model was verified via an FE simulation. Vertical rolling simulations were performed using the roll gap that was calculated via the respective SSC model for each steel slab. Horizontal rolling simulations were also conducted. Cropping lengths about the head and tail ends that were regulated by width control standards of the specific work site were compared.

这项研究的目的是使用有限元（FE）分析来分析板坯首尾两端的宽度变化，并进行适当的短行程控制（SSC）模型。根据分析结果滚动。利用线性回归方法推导了过程变量与板坯首尾两端的变形之间的关系，包括宽度收缩率和宽度收缩长度。通过考虑板坯变形量，开发了一种用于垂直-水平轧制过程的高级SSC模型。通过有限元仿真验证了所提出的SSC模型。使用轧辊间隙进行垂直轧制模拟，该轧制间隙是通过相应的SSC模型为每个钢坯计算的。还进行了水平滚动模拟。比较了由特定工作地点的宽度控制标准所调节的头端和尾端的裁剪长度。
