Blast furnace operation closed-loop control system

Abstract

The invention discloses a blast furnace operation closed-loop control system. The closed-loop control system is connected to a blast furnace production control system and comprises a furnace heat prediction module and an actuating quantity output module. The furnace heat prediction module is connected to the blast furnace production control system, acquires blast furnace running data, and generates current furnace heat parameters and trend furnace heat parameters based on the blast furnace running data. The actuating quantity output module is connected to the furnace heat prediction module, acquires the feed data of a practical actuating quantity, and adjusts the feed data of the practical actuating quantity according to the current furnace heat parameters and the trend furnace heat parameters generated by the furnace heat prediction module to generate actuating quantity adjustment parameters. The blast furnace operation closed-loop control system can realize automatic closed-loop blast furnace operation control without manpower, so it is in favor of improving the whole level of the blast furnace operation, stabilizing the blast furnace condition, and eliminating individual operation differences.

Description

technical field [0001] The invention relates to the field of blast furnace production operation, in particular to a closed-loop control system for blast furnace operation. Background technique [0002] In the process of blast furnace production and operation, the technical level of the blast furnace operator has a decisive impact on the furnace condition, output and life of the blast furnace. During the blast furnace operation, it often happens that the furnace condition is not smooth for several days due to the wrong judgment of the operator, and even serious accidents such as furnace cooling may occur. In recent years, several vicious accidents such as blast furnace burn-through explosions have occurred in the blast furnace industry, which have brought huge losses to people's lives and property. In addition, with the large increase of domestic blast furnaces, there is a large shortage of skilled employees, and it takes a long time span to cultivate professional blast furn...

Problems solved by technology

The common problem in these systems is that operators still need to analyze the parameters calculated by the model, and then perform operation processing

Due to differences in individual technical levels, it will inevitably lead to differences in both analysis and processing, which will eventually be reflected in the fluctuations in blast furnace production, resulting in lower output, increased fuel consumption, and unstable molten iron quality.
