Abstract

A lining structure for a molten-metal container for containing a molten metal, wherein the lining structure is provided with: a steel shell constituting the outermost layer of the molten-metal container, the steel shell having a plurality of through-holes passing through an outer surface and an inner surface; a single-layer or double-layer permanent refractory layer provided on the inner side of the steel shell; a workpiece refractory layer provided on the inner side of the permanent refractory layer and at least partially composed of a castable refractory, the workpiece refractory layer forming an operation surface contacting the molten metal; and a plurality of layers of an insulating material that is a sheet-shaped polygonal member adjacently disposed with respect to the inner surface of the steel shell, the layers of the insulating material being installed between the steel shell and the permanent refractory layer or between two layers of the permanent refractory layer. A gap is formed between one of the insulating layers and at least one of the other insulating layers adjacently disposed with respect to the insulating layer, the gap being positioned on a through hole and having a thickness equal to or greater than the insulating material.
