    • Analysis of secondary refining slag parameters with focus on inclusion cleanliness 

      Pereira, Julio Anibal Morales; Rocha, Vinicius Cardoso da; Yoshioka, Ayumi; Bielefeldt, Wagner Viana; Vilela, Antonio Cezar Faria (2018) [Artigo de periódico]
      Secondary refining slag samples with different chemical compositions (45-54 % CaO, 7-13 % Al2O3, 20-29 % SiO2, 9-16 % MgO, 0-5 % CaF2) were investigated to verify the influence of their effective viscosity on inclusion ...

    • Effective viscosity of slag and kinetic stirring parameter applied in steel cleanliness during vacuum degassing 

      Rocha, Vinicius Cardoso da; Pereira, Julio Anibal Morales; Yoshioka, Ayumi; Bielefeldt, Wagner Viana; Vilela, Antonio Cezar Faria (2017) [Artigo de periódico]
      The process of vacuum degassing occurs during the secondary refining of special steels. Its main function is to remove undesirable gases. However, during this process, flotation phenomenon and inclusions absorption are ...
