Features of Blast Furnace Transient Processes

Resumo

The article considers principles of creating a logical dynamic model of the course of blast furnace smelting in a real time regime. It is based on actual operating behavior and its innovation, and data are provided for operation in this area that form the basis of this model or are used for its creation. Some blast furnace transient processes are studied. As a result of this, dependences are described for the effect of blast composition and parameters on molten product composition, and also the effect of charge composition on the gas dynamic resistance of a charge bed. Software is created demonstrating the relationships described with the aim of practical implementation of the model in question. Features of the blast furnace are provided for the transient processes considered, and practical recommendations are made for certain aspects of smelting.
