摘要: 在中厚板轧制力预报过程中,为防止自学习系数沿着厚度层别发生跳变,提出了中厚板轧制力自学习过程层别跳变的自整定方法.针对厚度层别表中的每一个厚度节点计算其半宽带,然后根据半宽带计算厚度节点的有效区域,最后找到当前轧制厚度的有效区域并确定它所对应厚度节点的权值,从而得出自整定后的自学习系数.实际应用结果表明,应用该方法后轧制力的预报精度及板形控制效果有了很大的提高和改善,具有良好的应用价值.

Abstract: In the prediction process of rolling force for plates, to prevent the self-learning coefficient from the skipping along thickness layers, a self-adjusting method was put forward in the self-learning process of the rolling force for medium/thick plates. In the method the half-width zone was calculated according to every thickness node as listed in the table of thickness layers, then the range of validity of a thickness node was calculated according to half-width zone so as to find out the validating range of the thickness during rolling and determine the weighted value corresponding to the relevant thickness node, thus giving the self-learning coefficient after self-adjusting. Practical applications showed that the method proposed is available to improve the prediction accuracy of rolling force and plate shape control greatly and worthy to apply to plate rolling.
