<P>PROBLEM TO BE SOLVED: To provide a method of dismounting a furnace with a multilayer refractory structure capable of reducing work load while securing safety against asbestos. Ž<P>SOLUTION: The method is used for dismounting the furnace with the multilayer refractory structure including a shell 61, a containing layer 62A covering the inner side of the shell 61 and formed by containing refractory materials 621, 622 containing asbestos, and a non-containing layer 62B covering the inner side of the containing layer 62A and formed by non-containing refractory materials 623-625 containing no asbestos to form multiple layers. After a primary dismounting process of dismounting the non-containing layer 62B from the core side while leaving the containing layer 62A and at least one layer 623 of the non-containing layer 62B brought into contact with the containing layer 62A as remaining parts 62C is performed, a secondary dismounting process of dismounting the remaining parts 62C is performed in accordance with countermeasures against asbestos.
