Analytical study of blast-furnace smelting operations performed with different blast temperatures and oxygen contents

Abstract

A multi-zone mathematical model developed by the Institute of Ferrous Metallurgy of the National Academy of Sciences of the Ukraine is used to analytically study smelting indices and smelting operations on a 5500-m3 blast furnace. The model makes it possible to determine the relationships that exist between processes which take place in the furnace and which affect the character of the smelting regimes and the final results. The study is performed for a wide range of blast temperatures, different oxygen contents in the blast, and different distributions of the charge materials over the furnace radius. New scientific results are obtained along with conclusions that can be put to practical use.
