  • Dephosphorization process for manganese alloys
    Patent number: 4752327
    Abstract: A method for dephosphorizing a manganese alloy by first desiliconizing the alloy to a level below 0.6%, and then dephosphorizing the low silicon alloy with barium carbonate or barium oxide in combination with an oxidizing agent. The lower the silicon content the better the results.

  • Dephosphorization process for manganese-containing alloys
    Patent number: 4684403
    Abstract: A method for dephosphorizing a manganese containing melt is disclosed. The method encompasses the addition of a magnesium compound to a manganese containing melt to form magnesium phosphides which are removed from the melt. The method is carried out under pressure and the addition of a flux in the melt is employed to facilitate the removal of the phosphides from the melt.
