METHOD OF DEMOLISHING A FURNACE OF A MULTILAYERED-REFRACTORY STRUCTURE

摘要

Disclosed is a method of demolishing a furnace of a multilayered-refractory structure having an iron shell (61), an asbestos-containing layer (62A) which covers the inner surface of the iron shell and is constituted of asbestos-containing refractories (621, 622), and multiple asbestos-free layers (62B) which cover the inner surface of the asbestos-containing layer and are constituted of refractories (623-625) containing no asbestos, the method comprising implementing a primary demolition step in which the asbestos-free layers (62B) are demolished from the core side of the furnace so that the asbestos-containing layer (62A) and at least one layer (623) of the asbestos-free layers (62B) which is in contact with the asbestos-containing layer are left as the remainder () and thereafter implementing a secondary demolition step in which the remainder () is demolished while taking a measure against asbestos.
