Determination of Kinetic Constants from Tests of Reducibility and their Application for Modelling in Metallurgy

Abstract

The paper analyses details for renewal of the research in blast furnace process within Research Centre ENET at VŠB – Technical University of Ostrava. A newly established laboratory for reducibility testing is an impuls to overcome the former limits and renew a research in its coherence after years. The paper deals with the possibilities of optimization of blast furnace operation. In the introduction, it sums up different approaches how to model blast furnace operation. It discusses the variety of optimal operation for different kinds of iron making technologies. It evaluates reduction course and reducing gas consumption in the stack of reduction aggregate. In the experimental, it creates kinetics model of blast furnace operating using Matlab mathematical library. It determines kinetic and heat limits of carbon consumption for different process conditions.
