In addition to these three components, it also contains components such as FeO, MnO, and P 2 O 5 , so it has been used for a broad range of agricultural purposes. Creates a general soil fertilizer containing a good balance of various fertilizer components needed by crops, including silicate, iron oxide, lime, magnesia, phosphate, manganese, and boron. Impact of Iron and Steel Slag on Crop Cultivation: A Review. Steelmaking slag deriving from BOF process (using the Linz-Donawitz (LD) converter) comes from the pig iron refining process, wh ich converts molten pig iron and steel scraps into high quality steel. 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. (Mar. 102, No. Properties and Uses of Steelmaking Slag. India: The Ministry of Steel has asked that the Ministry of Agriculture examine using slag from steel and iron production as a fertilizer. Silicate, lime, phosphate, and magnesia create healthy rice plants.

Silicified cells form on leaf surfaces, preventing rice blight. Although in recent years slag use has increased, the application for agriculture purposes needs to be further investigated. It is produced during the separation of the liquid steel from impurities in steelmaking furnace and is a non-metallic by-product of steelmaking process. Academia.edu no longer supports Internet Explorer. Converter slag as a liming agent in the amelioration of acidic soils. In industrial countries, the use of steel slag in agriculture is mature (Wang and Qing, 2006). Physical and chemical characterization of steel slag is a deciding factor of steel slag utilization as recycled raw material as road aggregate, cement … The increasing quantities of slag that are deposited on the land cause the removal of more and more lands from the agricultural circuit and an increse in the costs of recycling them. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. 2008), Zhang XiangYu; Zhang Hua; He PinJing; Shao LiMing; Wang RuYi; and Chen RongHuanBeneficial reuse of stainless steel slag and its heavy metals pollution risk.Research of Environmental Sciences 21(4): 33-37. Steel slag is by-product formed in the process of steel manufacturing. In agriculture, slag aggregates (Ag-Slag) have been used as an agricultural liming material since the 1920's in all types of crop production and landscaping. 2.2 Steel slag and limespoil: production and chemistry 9 2.2.1 Steel slag 9 ... 2.4.2.2 Utilization in the agriculture and construction sectors 26 2.5 Mechanisms of trace element mobility in soils and waste systems 29 . Available from: http://www.cwejournal.org/?p=5746, Download article (pdf) Citation Manager 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. Steel slag is a large amount of residual material produced in the process of steel manufacturing. In this paper, the common ways of resource utilization of steel slag in construction, agriculture, industry, and catalysis are reviewed. increases harvests by increasing the number of unshelled rice kernels and thousand kernel weight.
