Two-Dimensional Model of the Blast-Furnace Smelting of Hot Metal with 6 percent Ni

摘要

In organizing blast-furnace smelting, attention focuses on the structure of the column of batch materials and on the gas flow. The effectiveness of the process depends on the optimal combination of these two factors [1-4]. Therefore, the scope for analysis and prediction of blast-furnace operation will be expanded by simulation as a function not only of the blast parameters and batch composition but also of the metallurgical properties of the iron ore and coke. As a rule, the formation of the column structure in the blast furnace is monitored in terms of the gas composition and temperature over the charge-hole cross section. These factors are also considered in creating two-dimensional models of the blast-furnace process, so as to obtain a clear picture, in the first approximation, of how the charging parameters influence the change in thermal and reductive work of the gas within the furnace and over its cross sections and to relate practically all the basic aspects of the process to operational parameters of the furnace [5].
