Vitrification of electric arc furnace dusts.
Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits. Consequently, EAFD cannot be disposed of in ordinary landfill sites without stabilization of the ...
متن کاملRecycling Evaluation of Mill Scale in Electric Arc Furnace
A considerable amount of mill scale is generated from steelmaking plants annually. Although some industries use it as raw material however, since it contains iron in the form of FeO, Fe2O3, and Fe3O4, it can be considered as a valuable metallurgical raw material for iron and steelmaking industry as well. Thus, the aim of this study was to evaluate the possibility, efficiency, and consequences o...
متن کاملA KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST
In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...
متن کاملModeling and Control of an Electric Arc Furnace
Electric arc furnaces (EAFs) are widely used in steelmaking and in smelting of nonferrous metals. The EAF is the central process of the so-called mini-mills, which produce steel mainly from scrap. Typical EAFs operate at power levels from 10MW to 100MW. The power level is directly related to production throughput, so it is important to control the EAF at the highest possible average power with ...
متن کاملImproved modeling and optimal control of an electric arc furnace
ii ACKNOWLEDGMENTS I would like to thank my committee members, Professor Punam Saha and Professor Anton Kruger for their time and volunteering some of their summer to help. I would like to thank Professor Er-Wei Bai for all the direction, and always making me examine things more closely. I don't think I've ever met someone more excited about teaching. I'd like to thank Zhijun Cai for all the he...
