    However, manganese toxicity has occurred in people working in such occupations as welding and mining who were exposed to high amounts of manganese from chronic inhalation of manganese dust [1,39]. People who consume water containing high levels of manganese (in some cases as high as 28 mg/L) have also developed manganese toxicity [4,40].

    Manganese is added to steel in the form of ferromanganese to improve the rolling and forging qualities, strength, toughness, stiffness, wear resistance and hardenability. It is also used extensively as a deoxidizer. In view of its wide appliions, the consumption of ferromanganese is more than that of all other ferroalloys combined. However, ferromanganese is one of the main sources of ...

    Oct 10, 2015 · A small amount of CO2 (normally less than 10 %) is also produced because of the burning of this CO inside the BOF converter by reacting with oxygen (called postcombustion). Other reactions which take place because of the oxygen blowing are the oxidation of other elements such as silicon (Si), manganese (Mn), and phosphorus (P) etc.

    (, 2) [1, 7] According to the negative interaction coefficient seen in table 1 between phosphorus and chromium, high chromium content in the melt will disfavor the dephosphorization by decreasing the phosphorus activity in the melt. This will displace the equilibrium to the left, making the phosphorus stay in the melt, in eq. (1, 2). [1, 7].
