Potential Waste Heat Recovery Analysis From Molten Steel Slag…
Abstract. Every day, a huge amount of energy is released into the atmosphere in the form of waste heat. The search for a cleaner and more efficient society, not only at the industrial level but also at the domestic level, should avoid this type of emissions. Steelmaking is an example of an industrial sector with high optimization potential in energy management. In …

Analysis of compressive strength, durability properties, and
Slag has emerged as resource of significance in China. Nevertheless, the effective utilization of this resource remains below 30 % [10, 11].The composition of slag predominantly includes CaO, SiO 2, Al 2 O 3, and MgO.With an inherent potential for hydration activity, the sluggish pace of hydration necessitates external stimulation through adjunct agents [[12], [13], …

Classifying Slag as Non-Hazardous Waste
Andrew, and John, It will be important to remember that after being processed with the plasma the slag is no longer just a remnant of the steel as far as using it's MSDS. You have changed it's structure metallurgically, chemically, and physically. Without the analysis suggested by John it will be impossible to know it's exact nature as to rather it is Hazardous or not.
