Abstract

The invention discloses a method and a system for identifying chaotic characteristics of time sequences of CO utilization rates of blast furnaces. The method includes qualitatively identifying and analyzing the availability of the chaotic characteristics of the time sequences of the carbon monoxide utilization rates of the blast furnaces; determining embedding time and embedding dimensions of phase spaces of the time sequences of the carbon monoxide utilization rates of the blast furnaces by the aid of autocorrelation function processes and correlation integral processes, reconstructing the phase spaces of the time sequences by the aid of delay coordinate processes and computing numerical values of saturation correlation dimensions of the time sequences of the carbon monoxide utilization rates of the blast furnaces by the aid of saturation correlation dimension processes so as to obtain characteristic attribute values of the chaotic characteristics. The method and the system have the advantages that the carbon monoxide utilization rates of the blast furnaces can be effectively chaotically predicted and controlled by the aid of the method and the system, excellent guide effects canbe realized for energy consumption evaluation and field operation on the blast furnaces, and the purpose of reducing energy consumption can be achieved.

Description

technical field [0001] The invention belongs to the technical field of identification and analysis of the characteristics of the carbon monoxide utilization rate of a blast furnace, and relates to a method and system for identifying the time series chaotic characteristics of the carbon monoxide utilization rate of a blast furnace. Background technique [0002] Due to the existence of high energy consumption, the blast furnace ironmaking process has always been the focus of energy saving and consumption reduction in the entire steel industry. Therefore, the research on the evaluation index of blast furnace energy consumption can grasp and judge the change of energy consumption in real time, and guide the on-site operation to make corresponding changes. It becomes the key to achieve the purpose of reducing energy consumption. [0003] In the blast furnace smelting process, as a real-time energy consumption evaluation index of the blast furnace, the carbon monoxide utilization ...
