On the in-situ aluminothermic reduction of manganese ...
The in-situ aluminothermic reduction of manganese oxide (MnO) by dissolved Al in the continuous galvanizing bath was investigated. Thick (approximately 410 nm) MnO films were grown on a 5.1 wt.% Mn steel by annealing at 770 °C for 600 s using a conventional − 30 °C dew point N 2 –5% H 2 process atmosphere. The MnO films formed were then reacted with a 0.20 wt.% dissolved …

FERROALLOYS-FERROMANGANESE, SILICOMANGANESE, …
Generally ferro-manganese is produced in blast furnace or an electric furnace. There are no rigid ore-requirements for ferro-manganese produced in the blast furnaces. The high carbon ferromanganese is the most important grade of ferromanganese, which is produced by carbothermic reduction of high-grade Mn ores, and low iron content.
Aluminothermic reaction - Wikipedia
Aluminothermic reactions are exothermic stone reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron. The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself: . Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3. This specific reaction is however not relevant to the most ...
