Abstract

New experimental data are presented on the manganese equilibrium in liquid steel under simple slags consisting of the oxides of iron and manganese with small amounts of impurities. The new data lead to values of KMn which are significantly higher than those of Körber and Oelsen and in general somewhat above those of other investigators.

Thermodynamic calculation from published data at lower temperatures gives results which agree fairly well with the experimental data.

The distribution of oxygen between these slags and the liquid metal conforms to the solubility curve of Taylor and Chipman.
