The former comprises of the integral The test is carried out at the replacement level of 10%, 20%, 30%, 40% at the ages of 7 and As the slag has a lower density than steel, it floats on top of the molten bath of steel. The water carries the slag in its slurry format to a large agitation tank, from where it is pumped along a piping system into a number of gravel based filter beds. Steel slag is a byproduct of the steelmaking and steel refining processes. Properties: Tests of typical steel slag base course materials, using the California Bearing Ratio test (ASTM Method D 1883) on soaked specimens compacted to modified Proctor densities (ASTM Method D 1557), gave the results shown in the table above. In this case, the slag is termed synthetic. JSPL has set … The steel slag is used as a secondary cementitious binder, or aggregates for road construction (Sheen et al., 2013; Manso et al., 2004). It was reported that the X-ray diffraction pattern of steel slag is close to that of Portland cement clinker. However, slags can contain metal sulfides and elemental metals. Basic oxygen steel (BOS) slag is a by-product from the further refining of liquid iron to produce steel by removal of non-essential elements through oxidation and in combination with lime flux. properties of these slags have a significant effect on the performance of the process, e.g. the selection of viscosity and solidification temperature are key to minimizing defects in the continuous casting of steel1, and the electrical conductivity of the slag determines the power supply requirements of many electric smelting processes2. The slag is removed from the vessel after the exothermic refinement of molten iron and recycled steel in the presence of fluxes and oxygen. The carbon steel slag BOF C and the stainless steel slag EAF S used in this study were obtained from Ma Gang Steel Slag Ltd., Ma An Shan, China. Depending on the intended steel quality (carbon steel or stainless/high alloy … The filter beds then retain the slag granules, while the water drains away and is returned to the system. JSW Steel has set up a unique BOF slag granulation plant, producing slag with lower free lime content and is vigorously pursuing with BIS. Copyright © 2021 Elsevier B.V. or its licensors or contributors. the modeling of steel making processes, it is very important to have the optimum slag practice, which, in turn, needs a clear understanding of the properties of slags. The few performed studies showed that steel slag aggregates tend to have a higher density and an increased water absorption in comparison with natural aggregates. The liquid slag is tapped at temperatures around 1600 °C and allowed to slowly air-cool forming crystalline slag. Slag - Usage • Slag aggregates are approved for a number of uses although there are restrictions. Although the construction industry does use some slag as an aggregate, most is simply discarded. Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). Its bulk density is in the … Properties and Uses of Iron and Steel Slag MF 182-6 NATIONAL SLAG ASSOCIATION www.nationalslagassoc.org Page 5 Granulated blast-furnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. Physical properties of steel slag (De Brito and Saika, 2013). [citation needed]. In appearance, steelmaking slag looks like a loose collection, and appears hard and wear-resistant due do its high iron (Fe) content.
