Basic oxygen furnace. 1. Charging the furnace The BOS converter is charged first with scrap. This is used as a coolant. It helps to control the very high temperatures produced by the violently exothermic reactions in the furnace. After the scrap, three or four times as much hot metal (up to 300 tonnes) is poured into the furnace from a ladle.

factors: the use of carbon per ton of steel produced in an electric arc furnace is much smaller than the use of fuel per ton of hot metal in a blast furnace; and the overwhelming impact on carbon footprint for electric arc furnaces is due to their huge electricity consumption, some .

RECYCLING OF FLUE DUST INTO THE BLAST FURNACE

RECYCLING OF FLUE DUST INTO THE BLAST FURNACE

+

Blast furnace flue dust contains valuable amounts of carbon and iron. The contents of harmful trap elements are low enough for recycling into the blast furnace. Since 1993, SSAB Tunnplåt in Luleå has recycled the flue dust by charging it into the blast furnace in the form of a coldbonded dust briquette.

This paper examines the idea of using shredded scrap steel as a blast furnace burden material. Charging scrap, or metallics, with the burden offers several possible benefits including increased productivity and decreased fuel rate. In this paper, scrap charging is investigated numerically using a previously presented mathematical model.
