Optimization of deoxidizer sequencing, such as Al and Ti, is
an important topic which can provide improvement in terms
of inclusion composition and process stability. Nevertheless,
modeling inclusion nucleation and growth in a ladle is still a
challenge, since different complex mechanisms are involved.
The paper describes key steps which involve an important
modeling investigation. The first step deals with deoxidizer melting
in a turbulent steel bath. The second is devoted to nucleation
and growth of inclusions: thermodynamics criteria for inclusion
precipitation and turbulent agglomeration of clusters should be
simultaneously considered.
