Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces 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. Project description submerged entry nozzles (sens) are used in the steelmaking process to prevent reoxidation of the molten steel directly from stream contact with the surrounding environment and from air entrainment and splashing when the molten stream strikes the liquid surface in the mold. Basic oxygen steelmaking more than half the world's steel is produced in the basic oxygen process (bop), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel.

Steel slag definition and description of slag: steelmaking slags are the by-products of the processing of iron and scrap with lime into the desired type and grade of steel. Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone two processes, basic oxygen steelmaking (bos) and electric arc furnaces (eaf), account for virtually all steel production.

Steelmaking is the process for producing steel from iron ore and scrap in steelmaking, impurities such as nitrogen , silicon , phosphorus , sulfur and excess carbon are removed from the raw iron , and alloying elements such as manganese , nickel , chromium and vanadium are added to produce different grades of steel. Details of the steelmaking process vary depending on the kind of furnace, but most of the jobs are similar at a bof, workers known as melters direct the loading and melting of ingredients and the taking of samples for testing. Description of a blast furnace plant a blast furnace plant does not operate only its own blast furnaces but also a number of preparatory and auxiliary operations with relative autonomy.
