Steel slag is a by-product of steelmaking and refining processes. The conversion of iron to steel results in different types of steel slags. Depending on how these slags are formed, they are classi-fied into basic oxygen furnace (BOF) or electric arc furnace (EAF) slag. Further refining of the steel products from the BOF

Large volumes of slags are formed as by-products during the refinement of pig iron by basic oxygen steelmaking or electric arc furnace steelmaking. In order to lower the environmental impact of the steel industry and ensure its economic sustainability, there have been significant studies finding the ways to recycle by-products.The formation, composition and …

Ferrous slag from blast furnaces in steel plants and coal recyclables from coking plants are valuable, quality-controlled by-products. ...

Steel slag is a by-product generated from steel production through steel making furnaces and contains varying amounts of oxides, silicates, and other compounds. It can be used as a partial substitute for cement to produce various types of concrete mixtures with improved properties such as higher compressive strength, durability and durability ...

Steel slag (SS) is an industrial by-product of steel manufacturing, with an annual production of 150–250 million tons worldwide (Liu, G. et al., 2023). China is the largest SS producer in the world and the utilization rate of SS does not exceed 30% (Hao et al., 2022). Most SSs are landfilled or piled up, taking up precious land resources and ...

(DRI) or hot metal can also be used in the EAF route. The main solid co-products produced during iron and crude steel production are slag (90% by mass), dust and sludge. Process gases, for example, from the coke oven, BF or BOF are also important co-products. However, this fact sheet will mainly focus on solid co-products.

At the same time, for every tonne of endlessly recyclable steel that is made at an integrated steelworks, 600kg of valuable by-products are also produced for example, 400kg of blast furnace slag is made, which has many different applications, notably to reduce the carbon footprint of cement manufacture.

Slag is not a waste product, but rather an intentional byproduct or co-product of ironmaking and steelmaking processes. The molten slag surface layer that forms on top of molten pig iron or hot metal removes impurities generated during the reduction of metal ores to iron. A limestone flux is added into the blast furnance, …

Slag products. Heavy plates. Heavy plates for hydrogen application. Heavy plates for CO 2 applications. Heads and cones. ... As a global manufacturer of high-quality steel products, the Steel Division of the voestalpine Group assumes a …

Metallurgical slag, as a by-product of the metallurgical industry, has an increasing stockpile worldwide, which not only occupies land but also causes serious damage to the environment. …
