Abstract
In the previous paper of his investigations author showed the carbon and oxygen equilibrium in the molten steel fairly expressed by the two conjugated equilibria, FeO(Fe)+CO Fe+CO2(2) and C(fe)+CO2=2CO2 (3) Principal par of thet present paper is the investigation of thetemperature relationship of these equilibria up to 1, 650°C. According to his results of experiments, as far as the gaseous compositions are unchanged, the solubility of carbon in molten Steel in equilibrium with CO and CO2 mixture, tends to decrease and the contrary is true with oxygen solubility. The relationship of equilibrium constant and temperature also found for equilibrium (2), log K2=7, 450/T-4·66, and for equilibrium (3), log K2=-8, 800/T+7·40.
