Dissolution behavior of FeSi alloyts in a steel melt

摘要

The dissolution kinetics of ferroalloys in a steel melt is detrmined either by a heat transfer or by a mass transfer controlled phenomenon. When the ferroalloy has a lower melting point than steel, their dissolution process is characterized by a heat transfer mechanism, and a heat transfer model can be used to interpret their dissolution behavior. In the present work, this approach was used for FeSi alloys and Si metal which all have melting points below that of steel. Three grades of FeSi alloys, FeSi50(50wt
