摘要： 为实现中厚板全自动轧制,提高轧机利用率,研究了交叉轧制节奏控制问题.分析了交叉轧制的工艺特点,归纳出三类交叉轧制模式:均匀交叉轧制模式、对称交叉轧制模式和成组交叉轧制模式,并给出这三种交叉轧制模式的特点、可行条件、最佳开轧间隔时间及轧机利用率计算公式.考虑了辊道长度约束,对计算公式中的相关参数进行了调整,给出了一种节奏控制的启发式方法.计算结果说明,该方法比现有方法更准确,应用范围更广泛.

Abstract: The aim of schedule pacing control during composite multi-plate rolling is to make the plate rolling more automatic and increase the mill utilization. Analyzing the characteristics of composite multi-plate rolling process, three modes of the process are classified, i.e., equal-interval alternating, symmetric-interval alternating and grouped alternating. Thus the characteristics and feasible conditions for each of the three modes are described with the formulae of optimum time interval for starting rolling operation and mill utilization both given. Taking account of the restriction of mill table length, the parameters relevant to the formulae are adjusted properly to provide a heuristic method for pacing control. The computation results showed that the proposed method is more accurate than existing method with wider applications.
