- Abstract
To improve their properties, corundum-spinel castables were prepared using tabular corundum, reactive alumina and sintered magnesia fines as the main starting materials, reactive magnesia (RM) and calcium aluminate cement (CAC) as the binder, respectively. The apparent porosity, permanent linear change on heating, cold modulus of rupture, cold crushing strength, and corrosion resistance to CaO-Al2O3-Fe2O3-SiO2 (CAFS) slag of the two castables fired at 1 600 °C for 3 h were compared. The results show that, after heat treatment at 1 600 °C, compared with the CAC-bonded castables, the RM-bonded castables perform lower cold modulus of rupture and cold crushing strength, but significantly improved volume stability and corrosion and penetration resistance to CAFS slag.
