The two well-established methods predominantly used in steelmaking are the blast furnace-basic oxygen furnace (BF-BOF) and the electric arc furnace (EAF), with the former currently accounting for the majority (70.7%) of the global steel production [6].However, the decarbonization potential of EAF steelmaking has garnered interest in recent years, aligning …
The review covers three main types of slag—basic-oxygen furnace (BOF), electric-arc furnace (EAF), and ladle furnace (LF) slag—and explores their diverse characteristics. While steel slag shows promise for enhancing the properties of concrete, further research is needed to develop scalable treatment methods ensuring volumetric stability.
Overview. Our dry slag granulation technology transforms molten slag from steel furnaces into granules using air stream, eliminating the need for water. The flexibility of the process allows obtaining granules of different sizes and with …

Electric arc furnace (EAF) slag, one of the SM slags, is produced by refining the process of recycled steel scrap in the electric arc furnace. The main chemical characteristics of EAF slag are its high free calcium oxide (free-CaO) and Fe oxide content. It has been reported that these two compounds cause the volumetric instability of EAF slag.

The results show that the disintegrated ladle slag was made volume stable by water granulation, which consisted of 98% glass. However EAF slag 1, EAF slag 2 and the BOF slag formed 17%, 1% and 1% glass, respectively. The leaching test showed that the glass-containing matrix did not prevent leaching of minor elements from the modified slags.

Abstract Laboratory treatments of a plant EAF slag sample 71686 were conducted using stabilizers containing P 2 O 5 and air granulation. The results show that it is necessary to add the stabilizers to increase contents of P 2 O 5 from 0.39% to 0.7% for the slag stabilization.

Outotec Slag Granulation Typically, slag is granulated by using water sprays during tapping. Granulation is a cost-effective way to process slag for further usage. Because the granulation process uses water recycled from other water circuits in the plant, fresh water intake is minimized. Outotec Furnace Lining Monitoring System
To solve the problem of difficult utilization of steel slag, the liquid steel slag was modified and the air-quenching granulation process was carried out to make steel slag into a value-added end product: air-quenching granulated steel slag. The granulated slag was tested to analyze the variation rule of slag properties under different modification conditions. Based on …

The composition of EAF slag is similar to BOF slag, but the Fe 2 O 3 content in EAF slag is higher, approximately 1.23–46.14 % compared to BOF slag. LF slag is different from BOF slag and EAF slag. ... centrifugal granulation of steel slag and heat exchange. Initially, molten steel slag, at approximately 1500 °C, undergoes a high-pressure ...
Slag produced by the EAF route, both EAF and LF slag, is a critical waste for the steel industry which nowadays can be only partly utilized for further uses. Tenova developed a methodology for the design of a dry slag granulation process, applicable on both EAF and LF slag, based on CFD modellng validated by industrial trials performed in steel ...

absorption and density of natural aggregates and slag waste were evaluated according to UNI EN 1097-6 (Table 2). EAF granulated slag showed higher density than natural aggregates as a consequence of their high iron content (20 ÷ 30% vs weight). Hence, the higher the amount of slag was in the mix, the higher the density of concrete.

The CO 2 sorption performance of optimal steel-slag-derived sorbent is more stable than that of naturally occurring limestone, due to the low Si/Ca ratio and the presence of MgO with high anti-sintering ability. CaO-based pellets with high resistance to attrition and compression were produced by extrusion of the steel-slag-derived sorbent powders.
