摘要：<正>Expert systems are widely accepted to be used to support the operators of a blast furnace.Operational savings,improvements in furnace stability and product quality,have been shown in numerous,worldwide installations of the two leading systems,namely the VAiron Closed Loop Expert System and the VAIF Blast Furnace Expert System （former RAUTARUUKKI BFES）. The focus of the paper is to compare these two systems.Highlights of both systems, like closed-loop control or neural network applications,are presented and described.Details about these systems were published at conferences as well as in different magazines extensively-see literature chapter at the end of this paper. Experience and operational results achieved in several installations worldwide are presented. Currently,the advantages of the two systems are combined an advanced, state-of-the-art system.The main features of the new system,which will be the next step in blast furnace expert system based control,is also described in this paper.
