Deoxidized steel is steel that has some or all of the oxygen removed from the melt during the steelmaking process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling. As steel cools, excess oxygen can cause blowholes or precipitate FeO. Therefore, several strategies have been developed for deoxidation. This may be accomplished by adding metallic deoxidizing agents to the melt either before or after it is tapped, or by vacuum treatment, in which carbon dissolved in the steel is the deoxidizer.

  • L'acciaio effervescente (in inglese rimmed steel o rimming steel) è un tipo di acciaio a tenore di carbonio minore dello 0,25% e a tenore di manganese minore dello 0,60% avente un grado di disossidazione nullo o molto limitato per cui, durante la solidificazione in lingotteria, si ha lo sviluppo di ossido di carbonio con conseguente effervescenza.
