Features of dust formation in the oxygen-blowing of melts and possible uses of captured dust
This article examines features of smoke (dust) formation in a steelmaking furnace when the bath is blown with oxygen. Smoke formation is examined at every stage of the process – from the dispersal of the melt to the aggregation of particles in the flue system. Results are presented from the use of electron microscopy and thermodynamic calculations to determine the phase composition of the disperse-phase particles. Possible uses for the dust that is captured are discussed.
