摘要
以山东莱钢1号高炉和山西临钢6号高炉在线采集的[Si]时间序列为样本空间,容量为1000炉数据,利用相空间重构技术和G-P算法,得出莱钢1号高炉和临钢6号高炉冶炼过程的混沌吸引子的饱和关联维数分别约为3.36和3.12.由高炉冶炼过程混沌吸引子的饱和关联维数存在且为分数,可证明两座高炉冶炼过程存在混沌特性.
As [Si] time series of No.1 BF at Laiwu Iron and Steel Group Co. and No.6 BF at Linfen Iron and Steel Group Co. to be sample space, based on phase space reconstruction technology and G-P algorithm, the saturated correlative dimensions of chaotic attractor of Laiwu Blast Furnace Ironmaking Process and Linfen Blast Furnace Ironmaking Process are about 3.36 and 3.12, respectively. The existence of saturated correlative dimension with fraction value means there is chaos in both blast furnace ironmaking process.
