7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

The optimization model of optimal allocation of supplemental fuel and oxygen resources amongst blast furnaces in a blast furnace shop taking into account the change in smelting parameters was developed. This model allows to predict parameters of injected fuel efficiency for individual blast furnace in various technological situations. The model considers the static characteristics describing the influence of changes of melting conditions on overall economic indicators of the furnaces and includes the external and internal limitations on operation of individual blast furnaces and overall blast-furnace shop. Information - modelling optimization system of allocation of natural gas in a blast-furnace shop was developed and implemented. This model includes: input and adjustment of data; calculation module; optimization; output and the analysis of the results. The results of comparative assay of allocation of natural gas on the basis of operating data of the blast-furnace shop of OJSC “Magnitogorsk Iron and Steel Works” with 8 blast furnaces were obtained and implemented. Analysis of the results shows that the optimization model of joint distribution of natural gas and oxygen allows effective usage the available fuel and energy resources, taking into account the technological limitations in the operation of individual furnaces as well as a blast furnace shop in general.
