At present,the refractory materials which used in the blast furnace tapping trenches in China are mainly Al2O3-SiC-C castables.This paper reviewed the current research progress of domestic scholars to prepare new Al2O3-SiC-C castables by changing Al2O3 source,replacing carbon source,silica sol binder to replace aluminate cement and adding different additives.Finally,some suggestions for the development of Al2O3-SiC-C castables are proposed.
