Blast furnace charge distribution adjustment method, equipment and storage device based on classification of blast furnace conditions

Abstract

The invention provides a blast furnace distribution adjustment method and equipment based on blast furnace condition classification and storage equipment. Firstly, a wavelet noise removing method anda vague C mean value algorithm are adopted to obtain history blast furnace condition classification types and furnace state parameter clustering centers; different blast furnace condition classification types correspond to selected history distribution operation parameters one to one to determine history edge ore-coke ratio and center ore-coke ratio ranges for different blast furnace condition types; then, present blast furnace condition types are determined according to the obtained present blast furnace state parameters and the blast furnace state parameter clustering centers; and then, present blast furnace edge ore-coke ratio and center ore-coke ratio adjustment ranges are determined. The blast furnace distribution adjustment equipment based on blast furnace condition classification and the storage equipment are used for the blast furnace distribution adjustment method based on blast furnace condition classification. The distribution adjustment method has the beneficial effects ofhigh theoretical property and improvement of the distribution adjustment reliability, adaptability and practicability.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a blast furnace material distribution adjustment method, equipment and storage equipment based on classification of blast furnace conditions. Background technique [0002] Blast furnace is one of the important equipments of iron and steel metallurgy, and it is a continuous production process. The material distribution operation is the main means of controlling the blast furnace. The operation of the blast furnace includes a variety of operating states. These operating states correspond to different furnace conditions, and corresponding material distribution operations are required for different furnace conditions. Reasonable material distribution operation can not only reduce raw material consumption, keep the blast furnace running stably, but also improve the life of the blast furnace. At present, the adjustment of blast furnace material distribution mainly depends on the exper...

AI Technical Summary

Problems solved by technology

At present, the adjustment of blast furnace material distribution mainly depends on the experience of on-site staff and the expert system. Manual experience is too subjective and often cannot make correct judgments. In addition, the establishment of an expert system requires a lot of resources and cannot be extended to other blast furnaces.
