Investigation of the effect of silicon content in iron and its temperature
on exergy indicators of the blast furnace-converter system

Abstract. The aim of the work is to study the energy intensity of metal
products in the “blast furnace – oxygen converter” system during the
development of pulverized coal (PCF) in the blast furnace production. One of
the parameters characterizing the thermodynamic indicators of blast-furnace
smelting is the silicon content in liquid iron. A study was made of the effect of
silicon content in iron and its temperature on the performance and
thermodynamic indicators of steel production in the blast furnace – oxygen
converter shop chain during the development of pulverized coal in the blast
furnace. The calculated minimum and maximum values of changes in
productivity and consumption of coke, and exergy indicators with a change in
the silicon content in the iron. It is established that a decrease in the silicon
content and the temperature of iron in a blast furnace can reduce the loss of

exergy, increase the exergy efficiency, maintain a constant level or improve
environmental performance. However, reducing the temperature of the iron can
lead to significant disturbances in the operation of the blast furnace. It is shown
that silicon content in cast iron has the greatest impact in the blast furnaceoxygen shop technological system, a decrease of which contributes to an
increase in exergy efficiency, a decrease in exergy losses and an improvement
in environmental indicators. The temperature of the cast iron on the exergy and
environmental indicators in the “blast furnace – oxygen converter shop” system
has a minor effect, however, a decrease in the temperature of the iron can lead
to significant disturbances in the operation of the “blast furnace – oxygen
converter” complex.
Keywords: blast furnace, oxygen converter, PUT, silicon content in cast
iron, cast iron temperature, exergy and environmental indicators.
