India: The Ministry of Steel has asked that the Ministry of Agriculture examine using slag from steel and iron production as a fertilizer. Steel making slag (also: steel slag) is produced during the conversion of hot metal to crude steel in a basic oxygen furnace or during the melting of scrap in an electric arc furnace. Slag has been used in agriculture for some time, notably in the USA, Germany, and France, and it has proved both effective and cost-efficient. Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. 2.2 Fertilizers made from blast furnace slag and steelmaking slag Iron and steel slag can largely be divided into blast furnace slag and steelmaking slag. Physical and chemical characterization of steel slag is a deciding factor of steel slag utilization depending on the properties it can be used as road aggregate, cement and concrete admixture, soil stabilizer, construction materials, etc. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser. BENEFICIAL USE OF STAINLESS STEEL SLAG Rev. Steel slag and in particular LD and EAF Slag are being used extensively for various applications in many countries across the world including in USA, the European Union, Brazil, Australia and China. It might seem counter-intuitive, but steel slag has exactly the right chemical composition to do this. This research was carried out during the academic year 2008 with the aim of studying the effect of Steel Slag on Agricultural Topsoil. Marl and chalk are soft, impure forms of limestone and are sometimes used as liming materials, as are oyster shells. The quantities of slag obtained world wide are increasing, … Slag generated from basic oxygen furnace (BOF) or Linz-Donawitz (LD) converter is one of the recyclable wastes in integrated steel plants. As a major by-product of our industry, slag has long been sold by steelmakers for use in construction, but its use in agriculture has been less well known. Depending on the stage or type of steel making process, the slag generated is called High Sulphur slag, LD slag (Steel Furnace slag – SFS), LF slag or Electric Arc Furnace (EAF) slag. Steel slag is by-product formed in the process of steel manufacturing. Scrap steel reclamation – Steelmaking slag contains around 10 % scrap steel, which can be reclaimed through crushing, sorting, magnetic separation and screening process. engaging important agricultural land and causing grave pollution to the environment. Branca, E. Bonari and V. Colla Publisher: Faculty of Mechanical Engineering and Naval Architecture Steel LD slag has been successfully used as a substitute for limestone to neutralize soil acidity in agricultural soils for many years, and research has shown slag use to be comparable to or superior to limestone in some cases. Disposal of different wastes produced from different Industries is a great problem for any country. In Ukraine, we have been researching its value to farmers to improve soil properties and crop yield. Steel slag output is approximately 20% by mass of the crude steel output [1 ]. Properties of SSA . The slag from Split landfill in total quantity of 30.000 tons has not found its application till now. Steel slag is a large amount of residual material produced in the process of steel manufacturing. When pig iron is smelted in a blast furnace, the flux is added to the raw materials from the blast furnace in addition to iron ore and fuel (coke). Concrete. Iron blast-furnace slag should not be confused with steel-furnace slag or other types of slag. Hawai steel slag has been utilized in agriculture as a liming material for improving acid soil or as Si source for paddy rice and sugar cane plants. Piles of steel slag, a solid waste generated from the iron and steel industry, could be seen due to no utility found for the past century. Agriculture occupies a prominent position in Indian policy-making not only because of its contribution to GDP but also because of the large proportion of the population that depends on this sector for its livelihood. struction (as a stabilisation layer) and in agriculture (fine fractions are used for soil improvement).
