內容簡介Cr2O3-bearing castables bonded with reactive MgO(RM) or calcium aluminate cement(CAC) were studied to evaluate the binder effect on their performance in corrosive environments. The properties of the as-prepared castables were compared with respect to the differences in phase composition and microstructure. The corrosion behavior of the as-prepared castables by CaO-Al2O3-Fe2O3-SiO2-based slag was systematically compared via refractory cup testing at 1 600 ℃ with respect to the differences in phase composition and microstructure. The analysis indicates that RM bonded castables show higher apparent porosity, lower bulk density and strengths after drying at 110 ℃ and firing at 1 300 ℃, and higher permanent linear change after firing at 1 300 ℃, but better slag corrosion and infiltration resistance compared with CAC bonded castables.
