Electric arc furnace (EAF) steel bottom-blowing can effectively improve the temperature and composition uniformity of molten pool during smelting process. To explore effect molten-steel characteristics on at various stages smelting, we divided process EAF into four stages: melting stage, early decarburization intermediate ending stage. The numerical simulation software ANSYS Fluent 18.2 was use...

Argon oxygen decarburization (AOD) slag is the by-product of stainless steel refining process, which has caused considerable environmental stress. In this work, utilization AOD as mineral fertilizer for alfalfa (Medicago sativa L.) and perennial ryegrass (Lolium perenne planting were investigated by pot experiments. The morpho-physiological parameters biomass, plant height, root morphology bioc...

The increase in the level of greenhouse gases into environment, specifically carbon dioxide (CO2), leads to global warming, and limiting its emission has been a primary concern achieve neutrality by 2050. Among various methods decarburization, capture storage/utilization become paramount concerns for separation from exhaust gases. In this paper, widespread technological solutions CO2 are presen...
