steelmaking slag risk assessment

STEELMAKING SLAG: A SAFE AND VALUABLE PRODUCT

steelmaking slag poses no meaningful threat to human health or the environment. The following discussion describes the risk assessment scope and process, and summarizes the conclusions reached in the report. A thorough presentation and peer review of the risk assessments is expected to be published in the scientific literature

05/07/2018  Four different kinds of slags i.e., Blast furnace slag (BF), Linz-Donawitz converter slag (LD) Electric arc furnace slag (EAF), and refined slag or ladle furnace slag (LF) were obtained from POSCO, Republic of Korea. The slags were air-dried and made into powder form. The analytical procedures from the U.S. EPA Hazardous Waste Test Methods (USEPA SW-846) were followed to achieve the lowest ...

Assessment of Human Health and Ecological Risks Posed

The risk assessment found no significant hazards to human health as a result of the environmental applications of steel-industry slag. However, site-specific ecological risk assessment may be required for slag applications in and around small water bodies with limited dilution volume, because high pH and aluminum were found to leach at levels that may be harmful to aquatic life

Prior to the productive use of iron- and steel-making slags as environmental amendments, a risk assessment supported by material characterization concomitant with leaching and ecotoxicological testing is necessary. Five iron- and steel-making slags were characterized geochemically, and the leachability of their elemental constituents was assessed. The toxicity of slag leachate to microalgae ...

Continuous casting - Wikipedia

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.Since then, "continuous casting" has evolved to achieve improved yield, quality ...
