The invention relates to a ladle lining repair material. The ladle lining repair material is prepared from 5 to 3 mm recycled corundum aggregate, 3 to 1 mm recycled corundum aggregate, 1 to 0 mm recycled corundum aggregate, less than 88 [mu]m corundum fine powder, less than 88 [mu]m magnesia powder, less than 88 [mu]m soft clay fine powder, less than 88 [mu]m calcium aluminate cement, less than 5[mu]m silica powder, and less than 5 [mu]m alpha-Al2O3 micro powder, as well as a water reducing agent and explosion-proof fibers; the raw materials are uniformly stirred to obtain the ladle lining repair material. 9 to 12 percent of water is added into the ladle lining repair material to obtain repair pug; the repair pug is uniformly smeared on the surface of a ladle lining refractory material atthe smearing thickness of 1 to 3 cm; the ladle lining refractory material can be used after curing and baking. The ladle lining repair material has the advantages of being low in price, environment friendly, high in strength, high in corrosion resistance, long in service life, simple and quick; the service life of a ladle can be effectively prolonged by 20 to 30 percent, the cost of the refractory material is reduced and the production efficiency of the ladle is improved.
