| 摘 要： | 结合MAS平面形状控制要求，提出了5个技术解决手段：简化有限元仿真结果，得到楔形段尺寸计算模型；前滑计算公式采用全粘着摩擦条件；结合液压压下的控制周期对楔形段轧制时间进行离散化处理；辊缝设定需考虑不同位置轧制力波动产生的影响；通过多种检测手段的综合应用，实现准确的轧件尾部微跟踪。该技术在首钢中厚板厂实现了在线应用。实践表明，该轧制法对轧件矩形度控制有很好的效果。

| Abstract: | Based on the requirement of MAS method, five technical treatments are afforded. Online wedge size calculation model is got by simplifying the FEM simulation results. The slip model adopts the full-sticking-friction condition. The rolling time of the wedge zone should be discreted to cooperate the hydraulic screw-down control cycle. The gap-setting should consider the influence of rolling force variation in different position of the wedge. In order to micro-tracking the plate tail precisely different measure results should be comprehensively considered. The successful online application in Plate Mill of Shongang proved the MAS method has good effect on the plate plan view. |
