Environmental System Effects when Including Scrap Preheating and Surface Cleaning in Steel Making Routes

Thermodynamic optimization opportunities for the recovery and utilization of residual energy and heat in China's iron and steel industry: A case study

“…Ostman et al [19] investigated the system effect of scrap preheating and surface cleaning on energy consumption and CO 2 emission of a BF-BOF route. The analyses indicated that scrap surface cleaning made it possible to use shredded scrap and automotive shredder residue or other combustible waste to replace fossil fuels.…”

Preventing Wetting Between Liquid Copper and Solid Steel: A Simple Extraction Technique

“…The combustion of these substances during current EAF steelmaking is problematic, causing dust and pollution, [54] and alternative processes for preheating scrap while simultaneously removing or treating coatings are being developed. [55,56] Molten salt baths are currently investigated at the pilot scale as a more efficient and clean method to treat municipal waste. [57] Such setups are scalable, as molten salts are also widely used in metallurgy, for aluminum melting and steel heat treating.…”

Process integration analysis and some economic-environmental implications for an innovative environmentally friendly recovery and pre-treatment of steel scrap

“…In the steel industry, economic and environmental effects of using scrap preheating and surface cleaning have been analyzed by Östman et al [40] where it has been demonstrate that implementing surface cleaning leads to increased possibilities for recycling of otherwise non-recyclable material, as ASR (automotive shredder residues). This paper presents new processing technologies investigated within the research project ''Processes and technologies for environmentally friendly recovery and treatment of scrap" (PROTECT), which has received funding from the Research Fund for Coal and Steel (RFCS).…”
