Abstract

The invention provides a blast furnace condition forward prediction method, device and system, and relates to the technical field of gas prediction, and the method comprises the steps: collecting thecurrent production condition and current operation data of a blast furnace; Screening out historical production conditions matched with the current production conditions and a corresponding referencefurnace condition representation parameter value table from an operation historical database; Searching a current grade value range, a current evaluation score value and a current weight index to which the current operation value belongs in a reference furnace condition characterization parameter value table; And accumulating score values obtained by multiplying the plurality of current evaluationscore values by the current weight index to obtain a current furnace condition smooth score value, and further predicting the furnace condition smooth condition of the current blast furnace. The current blast furnace prediction accuracy is improved by taking the reference furnace condition characterization parameter value table corresponding to the historical production conditions as the currentjudgment reference. And by setting the grade and the weight index, the influence degree of the current operation data on the operation condition of the blast furnace can be reflected more clearly.

Description

technical field [0001] The invention relates to the technical field of coal gas prediction, in particular to a method, device and system for antegrade prediction of blast furnace conditions. Background technique [0002] In the daily production process of the blast furnace, it is necessary to predict and judge the blast furnace condition, and control and adjust the blast furnace according to the prediction and judgment results. Therefore, whether the blast furnace condition is stable and smooth has a very important impact on the production efficiency of the blast furnace. At the same time, it is also the key to improving the production capacity of pig iron, reducing fuel consumption, and prolonging the life of the blast furnace. If it is impossible to evaluate and judge the straight running condition of the blast furnace in time, various production technical indicators of the blast furnace will be greatly affected, so that normal production cannot be maintained, and serious ...
