The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (minimills) using an electric arc furnace process.
In the primary process crude steel is produced in two ways. In the first method the iron is produced from ore in the BF thus generating BF slag (BFS). BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method slags are generated in the scrapbased steel industry.
Slag is a byproduct of smelting (pyrometallurgical) ores and used metals. Broadly it can be classified as ferrous (byproducts of processing iron and steel) ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous materials like copper nickel zinc and phosphorus). Within these general categories slags can be further categorized by

Steelmaking Slag an overview ScienceDirect Topics. Apr 04 2012 · Steelmaking slag or steel slag is a by product from the production of steel during the conversion of hot metal to crude steel in a basic oxygen furnace or during the melting of scrap in an EAF The slag is generated as a melt and is a complex solution of silicates and oxides that solidify upon cooling 11 Depending on the specific
In these revised process routes slags of different compositions are produced in the variety of unit processes and hence the reuse of steelmaking slags has become much more complex. Clearly a thorough understanding of the design and use of these different slags is a prerequisite to the development of reuse strategies.
The article presents an overview of the methods of processing slag from Waelz process and various approaches employed by scientists globally aimed at processing such slags. Despite several listed methods of processing slag from Waelz process none entails a sufficient complex nature of its processing. In addition the slag processed from the Waelz process found in the dumps has not been
slag byproduct formed in smelting welding and other metallurgical and combustion processes from impurities in the metals or ores being treated. Slag consists mostly of mixed oxides of elements such as silicon sulfur phosphorus and aluminum ash and products formed in their reactions with furnace linings and fluxing substances such as limestone. Slag floats on the surface of the molten
Despite the wealth of information available on phase equilibria of oxide systems there remain many gaps and inconsistencies in the knowledge base. From an industry perspective there is an ongoing need to adequately describe the phase chemistry of slag systems in order to optimise process performance and improve productivity.
