Dust formation in a steelmaking reactor
Published online by Cambridge University Press: 25 October 2002
Abstract
To control the generation of dust in a steelmaking reactor, it is necessary to understand the
underlying physical mechanisms. An experimental device has been developed to study the
main emission mechanism, i.e. the projections from bursting bubbles. We visualized the burst
on liquid steel and quantified the subsequent emission. The chemical evolution inside the fume
exhaust system is simulated by thermodynamic calculations : the key parameters for controlling
dust mineralogy are the Fe/Zn ratio, the oxygen activity (p$_{{\rm CO_2}}$/p$_{{\rm CO}}$
) and the temperature
evolution.
