Study of the Possibility of Dephosphorization of Manganese-Containing Melts.

The results of a study of the possibility of carrying out dephosphorization of iron-manganese melts containing 10-15% Mn and 0. 090-0. 110%P are presented. The method employed for this purpose is based on the injection of powdery materials. The effect of the compositions of the powder mixtures and, consequently the compositions of the resulting slags on dephosphorization and manganese loss in the metal is considered. The injection of a powder mixture of optimal composition made it possible to obtain a degree of dephosphorization of the melt of about 40% with minimal losses of manganese left bracket 0. 10-0. 35% (abs. ) right bracket .
