Abstract

PURPOSE: To eliminate circumferential deviation on the inside of a blast furnace, by assuming the circumferential deviation from the silicon content of molten iron discharged from the furnace, temperature of the molten iron, and carbon monoxide at the lower portion of the furnace, and supplying air from tuyeres while controlling the moisture containing rate at each of the tuyeres.
