Problems solved by technology

[0005] Obviously, due to the many factors affecting the ironmaking process, the situation is intricate, and the judgment and control of the furnace temperature are complex and diverse, so negligence and mistakes are inevitable in operation based on experience, resulting in unsatisfactory furnace conditions, decreased production, increased consumption, and fluctuations in quality.
Moreover, the experience of the foremen of each shift is not consistent, and the operating level is also different, which leads to the fact that the blast furnace smelting process cannot be kept in the best state
[0006] It can be seen from the above that although the existing blast furnace production process has realized the local automation control of each sub-process, there are two important defects in the overall operational control of the blast furnace smelting process by the foreman i

Embodiment Construction

[0037] The method for utilizing the intelligent control system of the present invention to control blast furnace smelting includes establishing such as figure 2 The intelligent control system shown is equipped with No. 1 operating station (monitoring under-trough weighing system) and No. 2 operating station (monitoring winch system) for judging the working state of the blast furnace body, the thermal state of the blast furnace and the forward state of the blast furnace smelting process. In the main control room of the microcomputer monitoring system composed of the No. 3 operation station (monitoring the parameters of the blast furnace body), two microcomputers are set up at the No. 1 optimization station and the No. 2 optimization station which doubles as a server (database server 1). The operation station forms the local area network of the main control room, which constitutes the hardware platform for the intelligent operation of the foreman; at the same time, a local area ...

Abstract

The intelligent control system for blast furnace smelting includes the first and the second optimizing stations in the main control room and several operation stations to constitute microcomputer LAN; and server in the iron smeltery connected to various control step terminals to constitute iron smeltery LAN; and the iron smeltery LAN is connected with the main control room LAN to constitute one network system for real-time acquiring and automatic transmitting of process information. The first optimizing station is provided with intelligent control software module and the second with automatic display module. During operation, the intelligent control software module traces the smelting process via real-time data acquisition and operates automatically according to the data from the LAN, and the operation results are output in man-computer dialogue and simple graphic display mode.

Description

technical field [0001] The invention relates to a method for controlling blast furnace smelting by using an intelligent control system. Background technique [0002] Among the various production processes of iron and steel complexes, the blast furnace ironmaking process is the most complicated. [0003] The existing blast furnace smelting system includes sensors for online dynamic collection of blast furnace data, and a computer monitoring system composed of several operating stations equipped in the main control room of the blast furnace to judge the working status of the blast furnace body, the thermal status of the blast furnace and the forward status of the blast furnace smelting process. The various control procedures and information transmission processes of the ironmaking process are as follows: figure 1 Shown: The on-duty foreman organizes the production process of blast furnace ironmaking in the main control room of the blast furnace: the ...
