PURPOSE:To form a foamless uniform lining on the inside wall of a metallic vessel and to increase the lifetime thereof by pouring castable refractories which are deaerated by oscillation in a hopper through an inflow pipe into the spacing between said vessel and molding flask disposed therein from the bottom. CONSTITUTION:The molding flask 3 is disposed in the vessel 1 for molten metal. The hopper 5 is oscillated to remove the foam contained in the castable refractories existing in the hopper. The deaerated pouring material 4 is poured through a pouring pipe 8 into the space 7 between the vessel 1 and the flask 3 from the bottom. The material 4 fills the space 7 in the foamless state and forms the lining material having the increased lifetime.
