The basic oxidizing mechanism of the barite mill is to place the steel parts in a solution containing sodium hydroxide, nitrate or nitrite and to surface treatment at a certain temperature. When the temperature of the solution approaches the boiling point, the steel interacts with the oxidizing concentrated base as follows: the steel begins to dissolve, producing sodium ferrite and sodium ferrite.

 

At the same time, some of the sodium ferrite interacts to form a hydrate of ferric oxide (maroon precipitate). The appearance and protective properties of the oxide film vary depending on the thickness of the oxide film, but the main component of the constituent film is magnetic iron oxide regardless of the film thickness or film thickness.
