Improvement of blast-furnace smelting at PAO Severstal’

Abstract

In response to change in plant output and the hot-metal composition, unstable batch composition and characteristics, and increase in the recycled content, the maintenance of stable, economical, and highproductivity operation of the blast furnace shop at Cherepovets Metallurgical Works (PAO Severstal’) is of great importance. Particular attention focuses on increasing blast-furnace stability by improving the batch distribution within the furnace. The introduction of a blast-furnace technology with low slag yield (<250 kg/g of hot metal) is analyzed.
