Twenty five years’ experience with redesigned blast furnaces

Steel in Translation Aims and scope

Abstract

The operation of blast furnaces with a redesigned shaft, in which cooling is based on large cooled panels, is considered. The redesigned shafts prove more reliable and economically efficient than the traditional design (characterized by a housing, a cast-iron cooling plate, and a lining). At PAO MMK im. Il’icha, more than 100 mln t of hot metal has been smelted at the new blast furnaces. Experience shows that the new design extends the furnace run by a factor of 1.3–1.5, reduces the shaft’s repair time by 4–6 days, and reduces repair costs by a factor of 5–8. Furnace productivity is increased by 1.5–2.0%, with decrease in coke consumption by 1.5–3.0%.
