The modeling approach has been used on a fundamental model of a topblown converter. Reactions between gas–steel, gas–slag, steel–slag and gas–steel–slag have been considered. The results show that the mass transport in the surface area is totally controlled by convection. Also, that a large amount of CO produced during the decarburization might slow down the rate of decarburization in droplets ejected from the bath. For the present simulation conditions reflecting laboratory experiments, it was also seen that the amount of slag (FeO and/or SiO2) created is close to zero, . only gas (CO_CO2) is created as the oxygen jet hits the steel bath. It was also illustrated how an extrapolation of the decarburization rate, sampled from a few seconds of simulation, could be done to get a rough estimate of the carbon content at a later stage in the process as long as the carbon content is relatively high. The overall conclusion is that it is possible to make a dynamic coupling of the ThermoCalc databases and a CFD software to make dynamic simulations of metallurgical processes such as a topblown converter.

Introduction In many metallurgical processes involving an oxygenjet impinging onto a steel bath surface, a good understanding of the underlying fluid dynamics is desirable in order to optimize the involved kiics such as decarburization. There have been several experimental reports on the subject for instance1–7) and also some numerical or Computational Fluid Dynamics (CFD) –13) Szekely and Asai8) presented a putational model of a jet impinging onto a liquid surface.
