Innovative usages of stainless steel slags in

This paper deals with development of self-compacting concrete (SCC) containing stainless steel oxidizing slag (SSOS) and stainless steel reducing slag (SSRS) byproducts of the stainless steel makings. The oxidizing slag was employed as fine and coarse aggregates in substituting to conventional materials (sand and gravel) with various percentages (i.e. 0%, 50%, and 100%).

Steel Slag an overview ScienceDirect Topics

Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process. In the primary process, crude steel is

Effect of stainless steel slag waste as a replacement

2017-7-1  In the first process stage (BOF or EAF), steel slag is a by-product of the aggregate,. However, in the second stage of manufacturing stainless steel (ladle-furnace steel refining), stainless steel slag is generated as dust. The dusts are the most important by-product of

Steel Slag Aggregate an overview ScienceDirect

In analysis of the leaching characteristics of stainless steel slag aggregate, Ca and Si were found to be those elements most appreciably affected by carbonation due to the changes in the mineral phases responsible for solubility control of these elements [13]. The leachability of Cr, one of the most toxic elements in slag aggregate, appeared not to be significantly affected by carbonation, although Mo showed some reduction in leaching.

NSA 172-13 Slag and Its Relation to Corrosion of Ferrous M.

2019-12-15  energy areas and more active chemically. Chromium is added to steel to impart corrosion resistance by stimulating the formation of a protective oxide film on the surface. In stainless steel, films of chromium carbide can form in the grain boundaries. This depletes the chromium content from the surrounding areas and intergranular corrosion may result.

Chemical, Mineralogical, and Morphological

2011-10-26  During the steel refining period, oxygen is injected into the molten steel through an oxygen lance. Some iron, together with other impurities in the hot metal, including aluminum, silicon, manganese, phosphorus, and carbon, are oxidized during the oxygen injections. These oxidized components combine with lime (CaO) to form slag.

Stabilization of Stainless Steel Slag via Air Granulation

In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C2S) to γ-dicalcium silicate (γ-C2S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and dust generation.

Up-Concentration of Chromium in Stainless Steel Slag

Slags coming from stainless steel (SS) and ferrochromium (FeCr) production generally contain between 1 and 10% Cr, mostly present in entrapped metallic particles (Fe–Cr alloys) and in spinel structures. To recover Cr from these slags, magnetic and gravity separation techniques were tested for up-concentrating Cr in a fraction for further processing. In case of SS slag and low carbon (LC
