86 IRON AND STEEL SLAG - USGS

2020-2-7  U.S. ferrous slag production, but domestic slag sales1 in 2019 were estimated to be 17 million tons valued at about $470 million. 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 arc furnaces accounted for the

Iron and Steel – Analysis - IEA

In 2018, the energy intensity of steel1 fell by 3.6%, compared with 1.3% average annual declines from 2010 to 2017. While these recent reductions are positive, they resulted primarily from energy efficiency improvements in conventional production processes, as well as a small increase in scrap-based production, rather than from a transformative change towards low-carbon steel production methods.

Steelmaking Process - an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
