Steel Slag an overview ScienceDirect Topics
In the primary process, crude steel is produced in two ways. In the first method, the iron is produced from ore in the BF, thus, generating BF slag (BFS). BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry.

Basics of slag production Article on the slag industry
Oct 27, 2011Slag from the production of ferrochrome is also included here; this material is produced in substantial tonnages and the main use of ferrochrome is in the steel industry. Slags also arise from other processes, particularly the smelting of non-ferrous metals, but these materials can be very different and each needs to be studied individually.

Comprehensive Analysis of Steel Slag as Aggregate for
Jun 28, 2021Steel slag is the main source of solid waste in the steel industry [1]. It is obtained either by melting scrap with a high electric current in an electric arc furnace (EAF) or by processing hot melted metal, scrap and fluxes with lime in a basis oxygen furnace (BOF).

Steel Slag Material Description User Guidelines for
Mar 08, 2016The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

Metal slag processing // REMONDIS´ Lippe Plant
What is metal slag? The production of high grade steel begins in electric arc furnaces. These use electrical energy to melt down metal scrap and alloying elements. The whole process takes place using electrodes which are lowered into the material and create temperatures of up to 3,500°C.

Steel Slag an overview ScienceDirect Topics
Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction ( Sheen et al., 2013 ; Manso et al., 2004 ).

Basics of slag production Article on the slag industry
Oct 27, 2011With world steel production now well over a billion tonnes per year, the slag that arises from some of the processes involved is a major resource. Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser.

Comprehensive Analysis of Steel Slag as Aggregate for Road
Jun 28, 2021Around 70% of the world’s steel production depends on the blast furnace process (integral route), as the availability of scrap limits electric arc furnace production to 30% of global demand . In the BOF process, the amount of BOF slag produced ranges between 0.1 and 0.2 tonnes per tonne of steel produced [3,4].

Slag aggregates Tarmac
Steel slag and old bank slags may undergo volumetric expansion in the presence of water. The risk of damaging expansion occurring when using steel slag produced in modern processes is minimised by a combination of careful production control and processing. Air-cooled blast furnace slag is non-expansive.
