ABSTRACT
To diagnose the lining condition of the blast furnace hearth during its campaign, are widely used
methods based on the analysis of the temperature characteristics of the
refractory lining. Measurement of the temperature characteristics is performed
by means of a few hundred thermocouples placed inside the refractory lining.
The peculiarity of proposed and used mathematical models is a fully
three-dimensional assessment of the refractory lining, presence mechanisms of
adaptation to the actual thermal conductivity of refractories and optimization
calculations to the work in the on-line mode. The new monitoring systems of the
lining wear of the blast furnace hearth are established on 5 blast furnaces of
integrated iron-and-steel works of China: No.4 by volume 3,200 m3 of “Jinan Iron & Steel Company” in Jinan (683
thermocouples), No.2 by volume 1,080 m3 of
“Henan Jiyuan Iron & Steel (Group) Company” in Jiyuan (212 thermocouples), No.4 by volume 2,500 m3 of
“Guangxi Liuzhou Iron & Steel (Group) Company” in Liuzhou (383
thermocouples), No.3 by volume 1,750 m3 of “Jinan Iron &
Steel Company” in Jinan (524 thermocouples); No.1
by volume 1,750 m3 of “Jinan Iron & Steel
Company” in Jinan (524 thermocouples).
