DEVELOPMENT AND FILLING OF THE INFORMATION SYSTEM “OUT-OF-FURNACE IRON PROCESSING” WITH INDICATORS OF COMPLEX IRON PROCESSING
Abstract. he aim of this work is to continue the development and updating of the information system for out-of-furnace cast iron treatment “POCH” with indicators of complex cast iron treatment. Modern steel production is characterized by an increase in the production of steels with a low content of non-metallic inclusions. Out-of-furnace pig iron refining is widely used to provide BOF processors with pig iron of a given quality, which significantly reduces the cost of producing high-quality steel products. Updating the database with information on technologies for not only pig iron desulphurization, but also complex impurity removal will allow us to obtain descriptive models for these technologies and become the basis for algorithmic support of the expert system’s analytical block for the selected pig iron refining technology. The Out-of-Furnace Iron Processing Database “POCH” is a full-text form of documentary database organization and makes it possible to provide a thematic search for a particular problem or a certain issue, which is regulated by a corresponding query provided with a flexible interface. The information support subsystem was developed, in particular, a software module for the automated procedure of replenishing machine passports formatted according to a special template from the User’s technological information archive in Excel was developed. The analytical unit was supplemented with a subsystem for analyzing the processes of interatomic interaction in the metal-slag system using the concept of directed chemical bonding, generating complex indicators, and assessing the role of individual components of the mathematical model. The dependences of the efficiency of impurity removal (S, Si, P) as a function of the properties of the injected slag, slag basicity, component content in the slag, and treatment intensity were analyzed. The architecture of the model system for expert evaluation of the technology of complex cast iron refining was developed.
Key words: cast iron, complex refining, efficiency, information system, database, parameters, integral indicators.
