摘　　要：介绍了动态轻压下技术在我国的应用情况,通过研究轻压下对连铸板坯枝晶生长的作用机理,引入ARCHON结构的专家系统,改善传统的辊缝控制。在离线状态输入轻压下控制规则,在线状态与ASTC协同调节扇形段位置、位移、压下速率,不断修正辊缝校验精度,实现扇形段辊缝的自动控制。The application of dynamic soft reduction technology in China was introduced,by researching the soft reduction in continuous casting slabs＇ dendritic growth mechanism,using expert system based on ARCHON structure,the traditional roller gap control system was improved.By input ing control rules in off-line condition,coordinately regulating segment position,displacement and reduction rate with the ASTC in online state,constantly revising the roller gap precision,the automatic control of roller gap in segment can be realized.
