discussed for a perspective of new clinker steel slag. Keywords: Accelerated Corrosion Environment, GBFS, SCM, Slag Clinkerization Steel Slag Introduction Steel slag is a by-product from the processing of iron (pig iron and/or steel-scrap) to steel in conversion furnace. By removing impurities such as Al, Si, P.during this process, steel
impurities from iron ore, steel scrap, and other ferrous feeds. The slag forms as a silicate melt that floats on top of the molten crude iron or steel and is tapped from the furnace separately from the liquid metal. after cooling to solid form, the slag is processed and may then be sold and/or returned to the furnace.
Steps have been taken all over the world to generate new ways of recycling or to reuse slag material. Advances have made it plausible to separate metallic scrap and lime in the slag. Slag has been considered as an alternative for submerged arc welding flux and even used for construction materials.
Clinker is a general name given to waste from industrial processes, particularly those that involve smelting metals, welding, burning fossil fuels and use of a blacksmith's forge, which commonly causes a large buildup of clinker around the tuyere.Clinker often forms a loose, dark deposit consisting of waste materials such as coke, coal, slag, charcoal, and grit.

The purpose of this study was to combine the physical pretreatments of grinding, sieving, and magnetic-separation processes to reclaim iron-rich materials from the desulfurization slag, and to use the remainder for cement clinker production. The iron-rich materials can be separated out efficiently by grinding for 30 min and sieving with a 0.3 ...

86 IRON AND STEEL SLAG (Data in million metric tons unless otherwise noted) Domestic Production and Use: When making crude (or pig) iron and crude steel, slagging agents are added to strip impurities from the iron ore in the blast furnaces and from the crude iron and scrap steel feeds to the steel furnaces.
entrapped iron, and other impurities, e.g., non-ferrous metals and silica. Based on the primary compositions, De-S slag may be considered as an alternative raw material for cement production. However, the impurities in De-S slag may affect the quantity or properties of the melt phase, which forms in the clinkerization process.
Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 (fluxing oxides). As oxygen is blown into the furnace, the principal flux (FeO) is generated. The "slag balance" now starts to shift and the slag becomes more liquid.
Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resource-conservation and energy-saving effects.
SLAG - IRON AND STEEL THM : Tonne Hot Metal Blast Furnace Slag In the blast furnace, the slag floating over molten pig iron (hot metal) is flushed out in slag pot and then sent to slag granulating plant or to cooling pits. Depending upon the cooling process, three types of slags are generated, namely, air-cooled slag, granulated slag and ...
