Consider de-oxidation by the addition of ferromanganese (60 percent Mn) to molten steel at 1600°C.The initial oxygen content is 0.04 wt%. It has to be brought down to 0.02 wt%. Calculate the quantity of ferromanganese required per tonne of steel. The manganese content of steel before de- oxidation is O.1 wt%. (MnO) + [Fe] = [Mn] + (FeO) Given: K Mp at 1873 K = 0.4.

Question
![Consider de-oxidation by the addition of
ferromanganese (60 percent Mn) to molten
steel at 1600°C.The initial oxygen content is
0.04 wt%. It has to be brought down to 0.02
wt%. Calculate the quantity of
ferromanganese required per tonne of steel.
The manganese content of steel before de-
oxidation is 0.1 wt%.
(MnO) + [Fe] = [Mn] + (FeO)
Given: K Mn at 1873 K = 0.4
K Fe-Mn at 1873 K = 0.156
Assumptions: Fe and Mn form ideal solutions](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1177a188-f776-4398-a967-32f07383624a%2Fa05b42ba-984f-4723-8e33-500f23ad5ee5%2F5vr9zqi_processed.jpeg&w=3840&q=75)
