• MgO saturation analisys of CaO-SiO2-FeO-MgO-Al2O3 slag system 

      Almeida, Rodolfo Arnaldo Montecinos de; Vieira, Deisi; Bielefeldt, Wagner Viana; Vilela, Antonio Cezar Faria (2018) [Artículo de periódico]
      Electric arc furnace (EAF) slag has a range of functions, including improving energy efficiency through the "slag foaming" phenomenon. As such, the study of slag is important in EAFs. One of the factors that determine ...
    • Slag evaluation to reduce energy consumption and EAF electrical instability 

      Vieira, Deisi; Almeida, Rodolfo Arnaldo Montecinos de; Bielefeldt, Wagner Viana; Vilela, Antonio Cezar Faria (2016) [Artículo de periódico]
      In steel mills that operate with electric arc furnaces (EAF), it is interesting to ensure greater stability to the electric arc to aim at less distortion in the electrical system, with consequent reduction in electric power ...
    • Slag foaming fundamentals : a critical assessment 

      Almeida, Rodolfo Arnaldo Montecinos de; Vieira, Deisi; Bielefeldt, Wagner Viana; Vilela, Antonio Cezar Faria (2017) [Artículo de periódico]
      Slag foaming is part of steelmaking process and could bring several benefits: it helps to save energy, improves productivity, enhances the refractory service life, decreases noise pollution and protects the bath from ...
