Activity of reducing steel slag of EAF

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2011
Reducing steel slag (RSS) was mainly acquired from five electric-arc furnace (EAF) steelmaking plants (among them, the products of two plants were carbon steel and those of other plants were stainless steel) for research tests. The chemical properties, compound compositions, activities and contents of main expansive compounds were tested.

Study of Chromium Oxide Activities in EAF Slags

Metallurgical and Materials Transactions B, 2015
The activity coefficients of chromium in Cu-Cr melts were determined by equilibrating liquid copper with solid Cr2O3 in CO-CO2 atmosphere. The temperature dependence of the activity coefficients of chromium in Cu-Cr melts could be expressed as $$ \lg \gamma_{{{\text{Cr}}\left( {\text{s}} \right)}}^{ 0} = \frac{{ 3 2 5 9\left( { \pm 1 8 6} \right)}}{

Wet versus slurry carbonation of EAF steel slag

Greenhouse Gases: Science and Technology, 2011
AbstractThe CO2 uptake and Ca‐to‐carbonate conversion yield attained by wet and slurry‐phase carbonation of stainless steel slag are reported. A maximum CO2 uptake of 180 g CO2/kg slag was achieved under wet conditions (50 °C, 3 bar CO2, 0.4 l/kg), corresponding to a Ca‐to‐carbonate conversion yield of 50%.

Experimental Database of EAF Slag Use in Concrete

2016
An experimental database about the properties of electric arc furnace slag is gathered. Data have been collected in literature from more than 40 research works, where the slag has been used in many applications, e.g. in mortar, concrete and for applications in bituminous mixtures.

MgO Refractory Attack by Transient Non-saturated EAF Slag

Metallurgical and Materials Transactions B, 2020
The gangue content in iron ore pellets that are used to produce direct-reduced iron (DRI) affects the slag volume during subsequent electric furnace steelmaking. Industrial and laboratory measurements and simulations have shown that unfluxed gangue from DRI also strongly affects the degree of saturation of the steelmaking slag with MgO.

Interfacial Reaction Between Magnesia Refractory and EAF Slag

2018
Magnesia-based refractory is generally used in an electric arc furnace (EAF) due to its relatively high corrosion resistance and strength at high temperatures. However, the magnesia refractory is attacked by EAF slag and thus the lining life continuously decreases. Thus, it is significant to identify the interfacial reaction between magnesia refractory

Assessment of EAF Steel Slag Solubility by Statistical Design

Advanced Materials Research, 2013
Electric arc furnace (EAF) steel slag solubility was studied using experimental design and statistical analysis. The solutions between pH 4 and 10, were mixed with the EAF steel slag for 0.5 hours at 350 rpm. The effects of the operating parameters, individually and their interaction, on the dissolution of slag elements were assess using full factorial

Characterization of Ceramic Tiles Added with EAF Slag Waste

Advanced Materials Research, 2014
The increasing production of steel leads to an increment of solid wastes generated especially Electric Arc Furnace (EAF) slag. This becomes a serious concern as the slag has to be disposed in a proper manner in order to avoid dumping in landfills which will eventually occupy available land and may cause permanent damage to the flora and fauna.

Alkali-Activated EAF Reducing Slag as Binder for Concrete

Advanced Materials Research, 2013
Electric arc furnace (EAF) reducing slag is the by-product of EAF steel-making. Currently, reducing slag is considered a waste material by the industry in Taiwan. Since the chemical content of reducing slag is similar to blast furnace slag (BFS), it is expected that reducing slag exhibits a similar pozzolanic effect as the BFS. This study used alkaline

Recycled concrete containing EAF slag: environmental assessment through LCA

European Journal of Environmental and Civil Engineering, 2014
A significant number of “green concrete” are being developed to meet the growing request of reducing construction industry impacts, saving raw materials and preventing industrial by-products’ discard. Between these, black/oxidising electric arc furnace (EAF) slag has been found to be suitable for structural concrete applications when used as ...
