根据Grassberger和Procaccia提出的Kolmogorov熵计算方法 ,以山东莱芜钢铁集团公司 1号高炉和山西临汾钢铁集团公司 6号高炉测得的铁水硅含量时间序列为样本 ,计算了各自的Kolmogorov熵分别为 (0 14 5 3± 0 0 15 1)nats·h- 1 和 (0 15 5 3± 0 0 14 0 )nats·h- 1 ,并估计了两座高炉铁水硅含量可预测的时间尺度分别约为 6 88和 6 4 4h .由Kolmogorov熵均为大于零的有限值 ,定量地说明了这两座高炉冶炼过程具有混沌性 ,同时提出用Kolmogorov熵值大小来诊断高炉炉况 .
According to the Kolmogorov entropy calculation method proposed by Grassberger and Procaccia, the Kolmogorov entropy of each sample is determined by the time series of the silicon content of hot metal measured by No. 1 blast furnace of Shandong Laiwu Iron and Steel Group Co., Ltd. and No. 6 blast furnace of Shanxi Linfen Iron and Steel Group Co., 14 5 3 ± 0 0 15 1) nats · h-1 and (0 15 53 ± 0 0 14 0) nats · h-1, respectively, and the predictable time scales for the Si content of two blast furnace hot metal were estimated to be about 6 88 and 644h. The Kolmogorov entropy is a finite value greater than zero, which quantitatively illustrates the chaos of the two blast furnaces. At the same time, Kolmogorov entropy is proposed to diagnose the blast furnace condition.
