Characterization Chemical Analysis. Figure 1a shows the weight fractions of the major elements present in AOD slag for the specific size fractions in the range < 25 µm to 1 mm. Figure 1b shows the same information for BOF. In both slags, calcium is clearly the most important element, while magnesium is the second most present alkaline earth …
This paper provides an overview of the different types of steel slag that are generated from basic-oxygen-furnace (BOF) steelmaking, electric-arc-furnace (EAF) …
Slag recovery: Turning a waste disposal problem into a business opportunity; • The slag-co product produced from the metallic recovery process fulfills important functions as construction materials for roads, ports, airports, and also as an environmental material for restoring or improving marine, soil, and other environments,
The bulk of steel production is met through the Basic Oxygen Furnace (BOF) route. In 2017, 71.6% (1206.9 million metric tons) of the world steel was produced through the BOF route[1].
In the conventional steelmaking process, slag is the second-largest byproduct. Although most slags have ways to be reused, the demand for small BOF (basic oxygen furnace) slag is still limited. This study aimed to develop a fluidized-bed chemical looping system using BOF slag as an oxygen carrier and methane as a fuel to produce …

Neglecting the jaw crusher, 47.2 kWh/t of energy were consumed in total. Leaching tests were performed at a size of —100 µm. ... 1–10 g of BOF slag—100 µm from ball mill grinding were added into a 1000 ml beaker filled with distilled water. The resulting suspension was agitated using a lab mixer at 680 rev/min and a 5 cm diameter ...
To avoid the volume expansion of basic oxygen furnace (BOF) slag for use in building materials, a hot slag modification process was proposed to reduce free CaO (f-CaO) in the molten slag. A transient 3D numerical model of BOF molten slag modification by SiO2 particles was established. The flow and heat transfer of molten slag, movement …
To avoid steel loss, the company has specially developed a patented, high-energy centrifugal mill capable of crushing fines and liberating the steel within the material. This helps increase the profitability of slag …
The moisture in steel slag when it enters the mill is 6.9%, and the Bond work index of the steel slag is 28.6 k Wh/t. The yield of the mill ground steel slag that is not treated via magnetic separation is 19.98% lower than that which is treated via magnetic separation. From this, it can be seen that the iron content in steel slag is ...
The BOF slag comprises C 4 AF, C 2 F, RO, and β-C 2 S and γ-C 2 S phases [106], [13]. Due to the high proportions of C 4 AF, C 2 F, and RO phases with elevated Fe content (including metal-Fe), the reactivity of BOF slag is lower than that of BFS [106], [13]. Consequently, adding BOF slag as an SCM in concrete reduces its …

Compression Crushing: Compression crushing, also known as compressive force, applies a compressive force to the material between two surfaces until it breaks.This way is frequently applied in jaw crushers and cone crushers. In jaw crushers, the material is squeezed between the fixed jaw and the moving jaw.
advantageous in that slag is used without such treatment as crush-ing. On the other hand, the cold recycling has the merit of freedom in selecting the type of slag and the timing of reuse. Upon conduct-ing BOF slag recycling, the effect of these characteristics was maxi-mized. 4.1.2 Maximization of the effects of hot recycling and cold recycling
