9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.

Standardization of methods for the use of steel slag has helped in increasing the utilization of the steel slag for those uses. Recently, novel uses are also reported such as mechanomutable asphalt binders, building material, green artificial reefs, thermal insulator, 13 and ceramic ingredient.

Blast furnace slag was about 50% of the tonnage sold and accounted for 88% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric ...

The predominant way of making steel in the United Sates is by using an electric arc furnace (EAF) to melt scrap steel, which results in the formation of a rock-like material called slag. Among its various applications, EAF slag is used in a loose or unencapsulated form as ground cover material for residential landscaping. However, the …

EAF slag is the steel-making slag generated from the EAF. It is reported that the EAF process is dominating the steel industry of the US with a 55% share of the total steel output in 2006. An EAF is different from a BOF, for example, in the way of energy supply where the former uses high-power electric arcs instead of gaseous fuels (as …

Uses of BOF-S. Steel Slag reuse generally falls into three main areas of application (Piatak, Parsons, & Seal, 2015): 2.1. Slag as a construction material, 2.2. Metal recovery from slag. 2.3. Slag use in environmental remediation applications. All uses are discussed according to the above three application areas.

Steel slag is a solid waste derived from the steel-making process, which accounts for approximately 15% of the total crude steel output (Furlani et al., 2010; Pang et al., 2016).
