Calcined Lime: Catalyst for Steel Quality and Production Efficiency
Calcined Lime: Catalyst for Steel Quality and Production Efficiency The role of quicklime in steelmaking Property Value / Description Name Calcined Lime Melting Point 2572 °C Boiling Point 2850 °C Solubility in Water Reacts to form calcium hydroxide (Ca(OH)₂) Density 3.1 to 3.4 g/cm³ Applications Desiccant (drying agent) Main Component Calcium oxide (CaO) Removal of harmful elements such as sulfur and phosphorus In the process of steelmaking, Calcined Lime is mainly used to remove impurities in the charge, especially harmful elements such as sulfur and phosphorus. When smelting iron in a blast furnace, Calcined Lime acts as a flux to react with sulfur and phosphorus to form compounds that dissolve in the slag, reducing the sulfur and phosphorus content in molten steel and improving the quality of steel. The removal of sulfur and phosphorus helps to improve the corrosion resistance and mechanical properties of steel, especially when manufacturing high – strength steel or ste...
