Abstract:
     This invention features that a portion of the flux needed for metallurgy of the blast furnace is fed into the furnace by blasting through blast furnace air nozzle for decreasing absorption of calcium oxide in the furnace materials by sulfur contained in the gas during declining process, which causes more sulfur content to be brought out by the gas. To reduce sulfur content entering the furnace means decrease of the sulfur content in the pig iron.
