About this site

The aluminothermic reduction process of manganese oxide from different slags by aluminum was investigated using pure Al and two types of industrial Al dross. Two types of MnO-containing slags were used: a synthetic highly pure CaO-MnO slag and an industrial high carbon ferromanganese slag. Mixtures of Al and slag with more Al than the stoichiometry were heated and interacted in an induction ...

Nov 01, 2012  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 Al bath at

ALUMINOTHERMIC REDUCTION Table 1 gives the heat balance for aluminothermic reduction for manganese oxides. It may be observed that when the ore is used as its is, i.e., MnO,, the reaction is violent because the heat available is much more than the heat required. Also if the are is reduced to IMO stage the material become more inert.

Aluminothermic reaction - Wikipedia

Aluminothermic reactions are exothermic chemical 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 ...
