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 ...

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...

The effect of the curing in a carbonated ambient of the solids obtained after the stabilization/solidification (S/S) of metallurgical waste using geopolymerization technology is described in this paper. The electric arc furnace (EAF) dust used to stabilize contains hazardous metals such as Pb, Cd, Cr or Zn. Different geopolymeric agents as potassium hydroxide, potassium silicate, metakaolin and...
