Key features of alumina/magnesia/graphite refractories for steel ladle lining
(2000-08-01)
The corrosion resistance of resin bonded alumina/magnesia/graphite refractories containing different kinds of aggregates were investigated when submitted to the action of slags of several CaO/SiO2 ratios. The laboratory ...
Análise térmica e energética do revestimento refratário de panelas de aço via modelos computacionais
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-07-30)
The secondary metallurgy is an energy-intensive step in the steelmaking process that requires an accurate adjustment of the composition and temperature of the molten metal during the ladle refining. In this context, the ...
Mathematical modeling of inclusion removal from steel during ladle teeming during inert gas injection
