Intelligent diagnosis and determination support system for blast furnace

Abstract

The invention discloses an intelligent diagnosing and deciding support system of blast furnace in the automatic technical domain of iron-smelting course, which comprises the following parts: 5 operating parameter detecting and control PLC of blast furnace as bulk PLC of blast furnace, hot wind furnace PLC, feed PLC, coal spraying PLC, assay chamber PLC, PLC and server, wherein the server communicates customer end through industrial Ethernet, which constitutes hardware platform of system; the software mode and database are operated on the server, which reserves disposed PLC detecting parameter in the database; the intelligent diagnosing and deciding support system of blast furnace are operated on the customer end; the data gathering software mode on the server and intelligent diagnosing and deciding system of blast furnace also adopt two-layered structure of program-database.

Description

technical field [0001] The invention belongs to the technical field of ironmaking process automation, and in particular provides an intelligent diagnosis and decision support system for a blast furnace. Background technique [0002] Blast furnace ironmaking is the main source of molten iron and steel, and it is the link with the most complex process, the most influencing factors, and the largest energy consumption in the entire process from raw materials to finished steel products. [0003] The existing blast furnace operation technology includes a complete basic automation system, and the operators mainly complete the production in the main control room. (1) The foreman conducts a preliminary analysis of the furnace condition according to the handwritten report of the previous shift when taking over the shift; (2) The foreman watches the hot air pressure, cold air flow, air permeability index, material ruler and other trend screens at any time, as well as cross temperature ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a blast furnace intelligent diagnosis and decision support system, which solves the one-sided problem of the foreman judging the furnace condition based on experience, the lack of data and analysis methods for process improvement, and the time-consuming and error-prone problems of hand-written reports. By thinking for the foreman, Help the foreman think and save labor for the foreman, give full play to the comprehensive role of computer artificial intelligence and auxiliary decision-making, reduce the frequency of abnormal furnace conditions to ensure smooth operation, and achieve the goal of "high production, high quality, low consumption, and longevity"
