Lime is put to use in primary steelmaking and secondary refining processes. Electric Arc Furnace (EAF) and Basic Oxygen Furnaces (BOF, QBOP, KOBM): Quicklime (dolomitic and high calcium) is used by steelmakers as a flux agent to efficiently and effectively remove impurities such as phosphorus, silica and alumina from scrap melting in the EAF.
Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
