Electric Arc Furnace Steelmaking

Lime is widely used as a flux due to its ability to bond with common impurities in the steel (e.g., silica, phosphorus, sulfur) and aid in efficient and effective slag formation. The slag has a lower density than steel and therefore floats on top of the molten steel, where it prevents direct contact between the molten steel and ambient air.
