DEVELOPMENT AND IMPLEMENTATION OF THE NEW
APPROACHES TO DIAGNOSTICS AND MANAGEMENT OF THE
BLAST FURNACE SMELTING

Summary. The article presents a brief description of the results of blast
furnace production research carried out at the Yenakiieve Iron & Steel Works
and the Dneprovsky Iron & Steel Integrated Works in 2011–2019. For the
conditions of transition modes of blast furnace to ensure its stability in
changing the qualitative and quantitative composition of the components of the
charge materials, as well as in the change of fuel additives in the blast, the
complex use of information of modern means of automated control is proved:
stationary thermosets and thermocouples to the lining. New approaches to the
choice of rational charging programs using the principle of variable maximum
ore loading along the radius of the furnace within the charging cycle for
working conditions on a charge of low quality have been developed. The
implementation of such a charging program over the next three years has
allowed to ensure a stable and economical course of melting, and its adaptation
to the technology of using pulverized coal has allowed to reduce the gas flow
temperature of the peripheral zone throughout the height of the blast furnace, as
well as to preserve the cooling system during the development of lining-free.
Expert module of adjustment of the program of charging using the established

rational ranges of change of temperature indices of gas flow distribution along
the radius of the furnace under different technological conditions of blast
furnace has been developed and implemented on three blast furnaces. The
method of reasonable choice of location of closed air tuyeres or air tuyeres of
different diameter was developed and tested using information on change of
lining temperatures on height and circumference of blast furnace. The method
of equalizing the raceway adiabatic flame temperature around the blast furnace
circumference by creating a non-uniform flow rate of pulverized coal in the air
tuyeres has been improved and implemented. The basic technological
requirements for blast furnace blasting after its long stop without release of
“gantry” cast iron and scraping of materials from the furnace, the use of which
before and in the blast furnace blasting of the Yenakiieve Iron & Steel Works
and the Dneprovsky Iron & Steel Integrated Works after a long-lasting set-up
were developed economic indicators, while ensuring the preservation of
refractory lining, structures and equipment.
Keywords: blast furnace, charging program, BLT, temperature probe, the
quality of coke, pellet content in the charge, lining, blowing of a blast furnace.
