Prevent release to air, sinks, drains, sewers, or water runoff.
All tests were conducted in a conventional electric arc steelmaking furnace (Lectromelt Corp, model ST) lined with a basic refractory brick and covered with a rammedalumina roof. Electric Arc Furnace Tests. Analytical data from backcharge tests indicated the furnace dust contained less zinc (32. 5 wt pct) than the dusts derived from the How can the answer be improved?electric arc furnace dust density Introduction. Electricarc furnace dust (EAFD) is byproduct of steel production and recycling and it is widely reported that about 1520 kg of dust is produced for each ton of steel produced 1. It is a complex, finegrained, highdensity material containing high amounts of zinc and iron, and significant amounts of calcium, manganese, magnesium,
Electric arc furnace (EAF) dust is a complex material generated during the steelmaking process varies essentially from one steel production unit to another by their morphological and chemical composition to a significant extent, , , . The chemical composition of the EAF steelmaking dust depends mainly on the scrap type and quality, charging electric arc furnace dust density The optimum EAF dust contents in coal ash mixtures were 1015 wt. and artificial lightweight aggregates having an apparent density under 1. 0 gcm 3 were produced at 1150 o C1200 o C in 10 minutes. Key words: Artificial lightweight aggregate, Bloating, Ferrous materials, EAF dust. MATERIAL SAFETY DATA SHEET TRADE NAME: Electric Arc Furnace Steel Slag SYNONYMS: Steel Slag, EAF Slag Steel furnace slag is not listed on the NTP, IARC, or OSHA VI. STORAGE AND SPECIAL PRECAUTIONS Respirable dust may be generated during processing, handling, and storage. Use personal protective equipment as noted in Section III. This dust contains hazardous, leachable elements such as zinc, lead or cadmium which require EAF dust to be stored in specific landfills. 1. The Electric Arc Furnace (EAF), designed for steelmaking from recycled scrap iron (Figure 1), also co produces between 15 to 25 kg of dust per ton of steel. The particle size distribution is heterogeneous with 60 between 0. 90 m and 4. 30 m and mean diameter of 1. 88 m. [10, [11. The largest recycling companies, to be economically viable, require that the EAF dust containing Zn concentrations greater than 15 [12.
