A method for dismantling a furnace having a multilayered refractory structure including: a furnace shell; a containing layer that is formed of a containing refractory that contains asbestos, and covers the inner side of the furnace shell; and a multilayered non-containing layer that is formed of a non-containing refractory that contains no asbestos, and covers the inner side of the containing layer, the method includes: a primary dismantling process; and a secondary dismantling process conducted after the primary dismantling process. In the primary dismantling process, the non-containing layer is dismantled from a furnace-core side thereof but the containing layer and at least one layer of the layers forming the non-containing layer, which is in contact with the containing layer, are left as a remnant. In the secondary dismantling process, the remnant is dismantled while asbestos measures are implemented.
