What is Nitrogen Control in Steelmaking Process about?

The document analyzes how nitrogen content changes during the molten steel production process of LDBAr-LF-RH-CC. It finds that nitrogen content decreases in the converter stage due to de-nitrification by CO bubbles. However, nitrogen rapidly increases after tapping due to exposure and absorption from argon blowing and alloy additions. Nitrogen continues rising in the ladle furnace likely due to arc exposure and additions. Finally, nitrogen decreases slightly in the RH refining stage through vacuum treatment
