Conclusions
-
1.
Silicon carbide can be used for deoxidation of high-temperature salt baths. It lowers the decarburizing activity and corroding capacity of the fused salts and ensures stable operation of the bath.
-
2.
Silicon carbide should be added in small amounts: 0.12–0.17 wt.% of the salts.
-
3.
It is sufficient to deoxidize the bath with silicon carbidge every 8 h (at the beginning of each shift).
