The investigating results are given in the article for the deoxidizing effect on the non-metallic inclusion compositions tubes steels melted in the vacuum induction furnaces with periclase lining. The oxygen thermodynamic activity was calculated for the lanthanum, cerium, alumina and yttrium melts during four heats. The magnesia spinel inclusion's formation condition was evaluated depending on the deoxidizer's used and on the deoxidizing depth. It was shown how the reduced alumina concentration during the steel ladle treatment governs the non-metal inclusions' compositions and on the possibility of their modification during the commercial tubes steels melting.
