Abstract

The invention discloses a blast furnace condition scoring method and system, and the method comprises the steps: carrying out the analysis of the data of key parameters and important technical and economic parameters of a blast furnace through adoption of a normalization interval analysis method, and obtaining a normalization linear equation; according to the absolute value of the dependent variable coefficient in the normalized linear equation, determining the scoring weight of the corresponding key parameter to the blast furnace condition; and quantitatively evaluating the blast furnace condition. Compared with the prior art, the blast furnace condition scoring method has the advantages that the normalized interval analysis method is used, the influence weight of the key parameters of the blast furnace on the important technical and economic parameters of the blast furnace is scientifically calculated, and the contribution degree of the key parameters to the evaluation of the furnacecondition of the blast furnace is determined, so that the furnace condition of the blast furnace is scientifically and quantitatively evaluated. Meanwhile, the method can also score the blast furnaces in different time periods, so that the furnace conditions of the blast furnaces in different time periods are determined, the production of the blast furnaces is effectively guided, the stability ofthe furnace conditions of the blast furnaces is facilitated, and the economic benefits of the blast furnaces are improved.

Description

technical field [0001] The invention relates to the technical field of blast furnace ironmaking production, in particular to a scoring method and system for blast furnace conditions. Background technique [0002] Whether the blast furnace runs smoothly is crucial to the stable production and consumption reduction of the blast furnace. Therefore, it is necessary to evaluate and predict the blast furnace condition, and control and adjust the blast furnace according to the predicted results. [0003] The currently developed systems for evaluating or predicting blast furnaces, such as blast furnace scoring systems or blast furnace data analysis systems, have the problems of lack of scientific basis and timeliness in evaluation standards to varying degrees. For example, the formulation of the optimal control range and control standards for blast furnace raw materials and operating indicators only relies on experience to set the weight of each parameter, and lacks data support and...
