It is commonly observed in the operation of electric furnaces, that the oxygen content of the steel melt is far more than the theoretical value for a certain carbon content.
In the present study, behavior of deoxydation due to the carbon in the steel melt was investigated, and the reason of retardation of deoxydation clarified, in view of obtaining reference data for improving the steel melting operation. The experiment was conducted with a Tammann furnace.
The sample was melted in a Tammann tube of magnesia. The author observed the behavior of deoxydation by varying the carbon and the oxygen content and reached the conclusion that the oxygen content agrees with the theoretical value when the carbon in the steel melt is small, while it becomes fairly more than the equilibrium-value when the carbon comes in excess of 0.2%. Besides, the author experimented the effect of varying temperatures and the effect of gas turbulance of the steel melt.
