Analysis of intelligent control system used for high efficiency smelting in blast furnace

It is a big dream of ironmaking workers to achieve the intelligent control of blast furnace. In recent 30 years,a large number of developments and practices have been implemented in many blast furnaces. Due to the complexity of blast furnace process control,it is difficult to obtain a good intelligent control system for realizing stable performance of blast furnace in despite of good performance for intelligent control system with single function. Some problems,such as range of study,contents,operational requirement, key issues to be addressed, have been deliberated based on the requirements of high efficiency smelting in blast furnace. Some proposals,such as emphasizing on the research of blast furnace with features of " multivariate, large time delay, nonlinear, full time and space", building high level data platform,using the simplest and most practical technologies,paying attention to the development and use of platform tools,constructing reasonable intelligent control development mode,simulating blast furnace experts,accurate positioning and priority to the easy,setting up a special software development team for blast furnace whole campaign optimization,have been proposed,a good object for upgrading one generation in 3 - 5 years will be achieved.
