Abstract
About 20 kinds of Ilmenite and Rutile type electrodes were tentatively produced and, with them, the phenomenon of SiO2 content of flux being reduced to Si and transferred to deposited metal was metallurgically studied. The results are summarized as follows :
1) The tendency of Si increase and Mn decrease differs depending on whether the slag is saturated with SiO2 or not saturated.
2) Referring to F. Korber's Equilibrium Diagram for the point immediately above the solidifying point of iron, the boundary line between Field I and II seems to be shifted to upper level.
3) The relations between apparent equilibrium constants and SiO2 content of slag and between basicity of slag and Si reduction were also studied.
4) Change of the mechanical properties of deposited metal with variation of SiO2 and Fe-Mn content in flux and appearance of fractured surface were also investigated.
