Disclosed is a tundish hole cover capable of preventing a thermal loss of molten steel inside a tundish by partly covering the cover hole in which a shroud nozzle is inserted. The disclosed tundish hole cover includes a fireproof body and a mesh inserted into the fireproof body as a reinforcing structural material. The fireproof body is formed by burning a molded object including 70-78 wt% of Al_2O_3, 19-25 wt% of SiO_2, and 3-11 wt% of additives and an organic binder. |
