BOF Steel Slag: Critical Assessment and Integrated Approach for

During steel production, the impurities in the hot metal react with the fluxes forming the steel slag. Chemical constituents of this steel slag (SS) are relevant to iron/steelmaking or blended cement manufacture. Harmful impurities present in it, however, limit its recycling to these applications. Japan, Europe, and the US consume a significant …

Recycling & Reuse of BOF

Basic oxygen furnace (BOF) steel slag is a main byproduct that is produced during the converter steelmaking process. The volume instability and fast crystallization of BOF slag limits its added-value application. This article aims to understand the effect of Al{sub 2}O{sub 3} on the mineralogical modification and crystallization kinetics of a ...

The Growing Importance of Steel Scrap in China

based on basic oxygen furnace (BOF) technology to electric arc furnace (EAF) technology that relies more heavily on scrap. In time, this shift will have a significant impact on scrap consumption trends both in China and globally. Today, scrap recycling in China is a highly fragmented industry that lacks vertical integration

Modification of industrial BOF slag: Formation of MgFe

Efficient recycling of iron oxide from industrial BOF (basic oxygen furnace) slags has always been an issue in metallurgy.In this study, a new method was developed for the efficient recycling of iron oxide: It was transformed into magnesioferrite spinel (MgFe 2 O 4) by mixing the industrial BOF slag with 6.00% SiO 2 first, and then the modified slag …
