Abstract: A mathematical model is developed to simulate melting processes of ferrosilicon block used for In-mold inoculation. Continuum formulations are used to describe momentum, hear and solute transports in the liquid, mushy and solid regions which are changed during melting processes of ferrosilicon block. Coupled calculations of flow velocity, temperature and solute concentration fields are carried out by using controlled-volume finite difference method. The obtained results are coincident with experimental ones basically.
