PURPOSE: A repairing method of refractories inside container is provided which improves adhesive strength on interface between a matrix of slip casting castable and a partial repairing material. CONSTITUTION: I a method for repairing a slip casting castable(1) inside container that is partially separated, the repairing method comprises the steps of removing a magnesian coating material(7) remained on the surface of the partially separated slip casting castable; injecting a mixed solution(3) having a viscosity of 60 to 490 centipoises prepared by mixing water with sodium silicate solution of water glass onto a repairing part of the slip casting castable from which the magnesian coating material is removed; constructing an alumina partial repairing material(5) on the mixed solution injected repairing part of the slip casting castable; and constructing the magnesian coating material on the surface of the alumina partial repairing material and the slip casting castable, wherein the water and sodium silicate solution are mixed in a mixing ratio of 1.4:1 to 1:4.9 in the mixed solution.
