Summary:PURPOSE:To obtain a molten metal holding vessel having excellent heat insulating characteristic, a little vol. reduction, long service life and little dangerous degree of molten metal leakage accident by making a permanent lining refractory layer in two-layer structure and disposing the specific thickness of heat insulating sheet layer between the two layers. CONSTITUTION:By disposing the heat insulating sheet 3b between the permanent lining two layers 5a, 5b, the permanent lining 5b at the iron shell side has no unfavorable influence of looseness of joint part by disposing the heat insulating sheet 3b. Further, the inside permanent lining layer 5a can be checked at the time of exchanging lining brick (one time for 1-2 months) and as necessary, the inside permanent lining layer 5a is partially dug out, to observe the condition of the heat insulating material sheet 3b. The thickness of heat insulating sheet layer is limited to 2-10mm.
