A pure {O}_{2} instead of air is used to oxidise the pig iron

Question

A pure $O_{2}$ instead of air is used to oxidise the pig iron because:

molten metal took up small amount of nitrogen which makes the steel brittle

air is not as efficient to oxidise all the impurities to their respective oxides

air contains moisture and will precipitate iron as

F e_{2} O_{3}

iron reacts with air to form

F e CO_{3}

If air is used for the oxidation of pig iron, the molten metal will take small amount of nitrogen. Hence, the steel will be brittle.
Hence, pure oxygen is used instead of air.
