Steel slag is an industrial waste from either the conversion of iron to steel in a basic oxygen furnace or from melting scrap to make steel in an electric arc furnace. It makes up a portion of approximately 15% of steel output. Most steel slag consists primarily of CaO, MgO, SiO 2, and FeO. Additionally, steel slag has cementitious

The EAF slag has a lower density than steel and therefore floats on top of the molten steel. Once the steel has been tapped into a ladle, the slag is either poured from the furnace onto the floor where it is cooled and removed for further processing, or into slag pots where specially designed vehicles are used to transport the slag to purpose ...

Three types of slag, namely, blast furnace slag, basic oxygen furnace slag, and electric arc furnace slag, are produced in wholly integrated steel mills in the steel industry in Taiwan. The so-called steel slag or steelmaking slag refers to basic oxygen furnace slag and electric arc furnace slag. A wholly integrated steel mill - GBFS & BOFS.

Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Depending on the cooling method used, it is classified either as air-cooled slag or granulated slag.

The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.

Granulated blast furnace slag (GBS) is the most important steel industry by-product. The production is almost 0.23 tons of slag for each ton of cast iron and 0.1 ÷ 0.2 tons for each ton of steel . According to EUROSLAG data, the production of granulated blast furnace slag was 23 million tons in 2012. The huge amount of EAF granulated slag ...

In tonnage terms, blast furnace slag is at present the main type followed by slags from the Basic Oxygen Steelmaking (BOS) and Electric Arc Furnace (EAF) processes. Various other processes such as external desulphurisation of steel may generate significant amounts of slag at some plants but overall they are only a small proportion of the total.
