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 will inevitably occur in the operation based on experience, resulting in unsatisfactory furnace conditions, decreased production, increased energy consumption, and fluctuations in quality. occur
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 p

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 main control room LAN as the master's operation platform; and servers 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 smelting, the intelligent control software module outputs the operation results in man-computer dialogue and simple graphic display mode, so that the master may control to keep the blast furnace operating in optimized state.

Description

technical field [0001] The invention relates to a system for intelligently controlling blast furnace smelting. 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 control 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. , each control sub-process and information transmission process of the ironmaking process is 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 ingredient weighing syst...
