The invention discloses self-flowing refractory castable which includes the following components in parts by weight: 25 to 45 parts of dense corundum, 15 to 35 parts of tabular alumina, 15 to 25 parts of fused white corundum, 5 to 15 parts of alpha-Al2O3, 6 to 12 parts of SiO2 ultrafine powder, 8 to 18 parts of pure calcium aluminate cement, 3 to 8 parts of sodium tripolyphosphate, 3 to 8 parts of sodium hexametaphosphate, 13 to 25 parts of magnesia aggregate, 5 to 10 parts of alumina-magnesia spinel, 5 to 10 parts of water glass, 3 to 8 parts of calcium carbonate, 2 to 6 parts of chromite, 1 to 5 parts of chromium hemitrioxide, 1 to 3 parts of aluminium powder, 1 to 3 parts of silica fume, 2 to 7 parts of pyromellitic dianhydride, and 1 to 6 parts of 3,3',4,4'-benzophenonetetracarboxylic dianhydride. The self-flowing refractory castable is good in mechanical strength and high temperature resistance.
