Lime, primarily composed of calcium oxide (CaO), is a chemical compound utilized in the steel industry to eliminate impurities from molten iron, specifically sulfur and phosphorus. When lime interacts with these undesired elements in molten steel, it produces slag, which can be easily removed, improving the quality and sturdiness of the steel. Lime is a fluxing agent in metallurgical processes.

Key Features:

• Impurity Removal: Lime interacts with sulfur and phosphorus to form slag, removing harmful elements from the steel and enhancing its long-term durability.
• Fluxing Agent: Lime serves as a flux by lowering the melting point of the impurities, allowing for their separation from the molten metal.
• Multiple Uses: Lime is applied in basic oxygen furnaces, electric arc furnaces, and other metallurgical operations to purify steel and to improve the quality of the metal.

Lime is an essential component to steelmaking processes, providing impurity removal, quality steel production, an essential fluxing agent, and slag formation. Due to lime's functionality in producing slag and improving process efficiency, it plays a vital role in modern metallurgical processes that continue to produce stronger and more resilient steel products.
