PURPOSE:To prevent damage on the rear lining of a vessel and to reduce the cost of refractories by reducing the thickness of the 1st step side wall lining brick to the thickness smaller than in the 2nd step and setting the height thereof at the height equal to the height of a floor lining brick or below. CONSTITUTION:The thickness of the 1st step A of the side wall lining brick 5 is reduced to the thickness smaller than the thickness of the 2nd step brick B and the height size thereof is set equal to or smaller than the height of the floor lining brick 6. The spacing between the bricks and the brick 6 is packed with the castable refractories 7 to form the inside part of the vessel for a mol ten metal, then the projection at the 2nd step B of the side wall lining brick presses the refractories 7 and to prevent the dislodgment thereof. Since a step is formed between the 2nd step B and the 1st step A, the infiltration of the metal is prevented. The damage on the rear lining of the vessel for the molten metal is thereby prevented.
