The invention relates to a working lining castable, in particular to a castable for a ladle lining or a working lining. The technical problem to be solved by the invention is to provide a castable used on a direct lining, in contact with molten iron, of a ladle, wherein the castable comprises the following components in percentage by weight: 8-20 percent of homogenized alumina with size of 12-18mm, 11-15 percent of sintered microporous alumina spinel with size of 8-5mm, 12-15 percent of sintered microporous alumina spinel with size of 5-3mm, 10-15 percent of sintered microporous alumina spinel with size of 3-1mm, 30-35 percent of sintered microporous alumina spinel with size smaller than or equal to 1mm, 0-5 percent of modified magnesia-calcium clinker with size smaller than or equal to 1mm, 1 percent of trichromium dicarbide powder, 3-5 percent of composite gel powder, 1 percent of hydrated alumina micro-powder, 1 percent of pearl-clay powder, 0.5 percent of bismuth germinate powder, 3-5 percent of modified pure calcium aluminate cement, additionally 0.1 percent of C7H10N2O2S, 0.1 percent of C21H14Na2O6S2 and 0.05 percent of 2-morpholineethanesulfonic acid. The working lining castable has the advantages that the high temperature performance and corrosion resisting performance of ladle products can be improved, the thermal shock resistance of the ladle is improved, the service life of the integrally casted ladle working lining is effectively improved, and the service life is improved by more than 30 percent relative to the conventional ladle working lining of the same type.
