The answer is c.
Basic oxygen steelmaking (BOS, BOP, BOF, and OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.The process is known as basic because fluxes of burnt lime or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter.

Factors affecting effective phosphorus removal in BOF steelmaking:
Phosphorus removal is a crucial step in the BOF steelmaking process to produce high-quality steel. Several factors play a role in determining the efficiency of phosphorus removal:
Higher FeO level in slag:
- FeO in slag helps in forming stable phosphorus compounds, aiding in its removal from the steel.
- Therefore, a higher FeO level in slag is desirable for effective phosphorus removal.
Higher basicity:
- Basicity refers to the ratio of basic oxides to acidic oxides in the slag.
- A higher basicity promotes the formation of basic phosphorus-containing compounds, facilitating their removal from the steel.
Higher temperature:
- Operating at higher temperatures enhances the kinetics of phosphorus removal reactions.
- It helps in reducing the viscosity of the slag, allowing for better mixing and transfer of phosphorus from the metal to the slag.
Lower temperature:
- Contrary to the previous point, lower temperatures can also aid in phosphorus removal by promoting the formation of stable phosphorus compounds in the slag.
- Additionally, lower temperatures can help prevent excessive foaming during the process.
NOT desirable factor for effective phosphorus removal:
- Higher FeO level in slag is not a desirable factor for effective phosphorus removal.
- Excessive FeO can lead to the formation of Fe3P, which is a stable compound and hinders phosphorus removal.
- Therefore, maintaining an optimal FeO level is crucial for efficient phosphorus removal in BOF steelmaking.
