3.4. Iron Slag: In this experiment the Iron slag collection is done from locally available iron furnace. Nowadays Iron products are used everywhere. Iron is durable and strong. It is obtained either from conversion of iron to Iron slag in a BOF (Basic Oxygen Furnace) or by the melting of scarp to make Iron in the EAF (Electric Arc Furnace). 3.5.
Slag formation is an essential part of the iron extraction process in the blast furnace. Slag is essentially a mixture of metal oxides and silicon dioxide; however, it can also contain metal sulfides and other elements. During the smelting operation, the limestone introduced as a 'flux' is critical to slag creation.
The CaCO 3 peak remains relatively stable after 5 minutes of carbonation, but at 120 minutes, the steel slag still contains phases with high iron content, as Brownmillerite in the steel slag exhibits limited reaction with carbon dioxide and is difficult to carbonate. The results showed significant changes in mineral phases, with the ...
Steel slag is a by-product obtained through the separation of molten steel from impurities in steel-making furnaces. It can be produced by different types of furnaces (blast, basic oxygen, electric arc, ladle furnaces). …

The stable hearth discharge is crucial for the operation of a blast furnace (BF). This study established a mathematical model for hearth discharge based on Bernoulli's principle, which considers the blast pressure, kinetic energy of molten iron and slag, gravitational potential energy, the pressure loss of molten iron and slag flowing through the deadman and taphole.
These findings corroborate the literature on SCMs, highlighting iron slag's role in improving concrete performance through reduced permeability, which is critical for structures exposed to moisture and aggressive environments. The implications include extended service …
A major difference between the NFM slags and other more commonly used SCMs is the high iron content in these slags [15], thereby yielding a higher Fe/Si, Fe/Ca and Fe/Al ratio compared to conventional SCMs such as blast furnace slag or fly ash, which could have an impact on the phase assemblage of hydrated cements.Several Fe-forms of typical cement …
Metal slag is a ferrous slag, industrial waste, and by-product of the iron industry produced during iron processing in steel plants due to removing impurities from iron ore [19]. The molten slag is a secondary raw material, a sintered metal product quenched under high water jet pressure to produce GGBFS [20]. The slag goes through 80% to 90% of ...

A cupola furnace is the most frequently used furnace aggregate for cast iron production. A by-product of the production of cast iron in cupola furnaces is cupola slag. Its amount is 40–80 kg per 1 tonne of the produced cast iron, and that is one of the reasons why this material is not as favoured as, for example, the blast-furnace slag. The purpose of this article …
