A series of lightweight ladle working lining castables were prepared with tabular alumina, microporous corundum, and calcium hexaaluminate (CA6) as aggregates, respectively, reactive α-Al2O3 ultrafine powder, SiO2 ultrafine powder, tabular alumina powder, and fused magnesia powder as matrices, calcium aluminate cement as a binder, and MgO ultrafine powder (D50=5.4 μm), Al(OH)3 ultrafine powder (D50=8.2 μm) as additives. The influence of aggregate and ultrafine powder on the physical properties, pore size distribution, thermal conductivity, thermal shock resistance, and slag resistance of lightweight refractory castables was investigated. The results show that calcium hexaaluminate (CA6) can make the castable lightweight, but increase the pore size and reduce the strength and slag resistance of castable. Using microporous corundum can reduce the bulk density of castble, and increase the proportion of micropores, which is beneficial to reducing the thermal conductivity, and improving the thermal shock resistance and slag resistance of castble. When MgO ultrafine powder and Al(OH)3 ultrafine powder are used as additives, the fluidity and strength of castable can be improved, the ratio of micropores in the castble can be increased, and the fracture energy, thermal shock resistance and slag resistance can be improved.
