Abstract

Effect of alloying elements of steel on the wettability between the steel melt and oxides was evaluated. Steels containing Ti, Nb, Mn and Al were melted on single-crystal and polycrystal plates of Al<SUB>2</SUB>O<SUB>3</SUB> and MgO, and the contact angle between the melt and the oxide plate was measured. Titanium addition to steel was found to decrease the contact angle both on Al<SUB>2</SUB>O<SUB>3</SUB> and MgO, but more titanium was needed to improve the wettability on MgO than on Al<SUB>2</SUB>O<SUB>3</SUB>. The addition of other elements, Nb, Mn and Al, did not improve the wettability between the steel melt and oxide plates. At the interface between Ti added well-wetted steel melt and oxide plate, reaction layer was formed. The layer was identified as Ti<SUB>2</SUB>O<SUB>3</SUB> for 1% Ti added steel and TiO for 5% Ti added steel. Thermodynamic calculation supported the formation of these reaction products. It was concluded that the improvement of the wettability was achieved by the formation of the Ti-oxide reaction layers immediately after the melting of the steel and that the contact angles decreased depending mainly on the materials of reaction layers.
