Dr Anton Andersson (Luleå University of Technology, Process Metallurgy)11/05/2026, 16:10EEC 4.F Exploitation of slag and by-productsOral Presentation
The transition to hydrogen-based reduction processes will alter slag compositions and volumes in ore-based steelmaking, with potential consequences for the established industrial symbiosis between steel and cement sectors. Presently, ground granulated blast furnace slag is widely utilized as a supplementary cementitious material (SCM), replacing clinker and thereby lowering the carbon...

In Korea, approximately 20 million tons of slag are generated annually from ironmaking and steelmaking processes, underscoring the need for effective recycling strategies. Since CaO, a major component of slag, reacts with CO2 to form CaCO3, the utilization of slag as a CO2 sorbent has paid great attention.

The decarbonization of the steel industry is accelerating the transition toward production routes such as direct reduced iron (DRI), hot briquetted iron (HBI), hydrogen plasma smelting reduction (HPSR), and electric smelting technologies. As a consequence, the volume and typology of electric arc furnace (EAF) slags generated across the steelmaking chain are expected to increase significantly....

Prof. Zushu Li (University of Warwick)11/05/2026, 17:10EEC 4.F Exploitation of slag and by-productsOral Presentation
Electric Arc Furnace (EAF) steelmaking, because of its flexibility, high energy efficiency and low emissions, plays a critical role in decarbonising the steel industry. EAF slag is a CaO-SiO2-FeO-MgO-Al2O3 system, comprising 30~60% CaO, 15~25% SiO2, 2~10% Al2O3, 2~15% MgO, and 10~30% FeO, depending on different raw materials used and varying EAF operating conditions. Majority of EAF slag is...
