Long term high performance operation at Kwangyang blast furnaces
Published online by Cambridge University Press: 06 April 2004
Abstract
Kwangyang has been operating five large size blast furnaces and K-1 BF
was relined in March 2002 after finishing 15 years of operation successfully.
To secure enough cast pig iron as one of countermeasures to a low HMR at the steelmaking
process during the relining period, four other blast furnaces came to increase their
productivity in advance, before the start of the K-1 BF long stoppage.
Particularly, during the ultra-high productivity operation period from March to June,
K-3 BF marked a new POSCO productivity record and a new silicon record simultaneously
on May in spite of unstable sinter consumption due to the width extension of
No. 1 & No. 3 sintering strands and 13 years furnace life. It was
2.76 t/day$\cdot$m3/IV in productivity and 0.15% in silicon level
in pig iron. These remarkable records were based on some advanced Kwangyang BF
know-how and recent developments like higher facilities reliability, optimum
allotment of hot blast and oxygen, high sophisticated burden distribution control
and special screening equipment of raw materials.
