Zusammenfassung:	To provide a dismantling method of a furnace body preventing falling of inner bricks when cutting, dividing and transporting the furnace body, when dismantling the furnace body laminated with the bricks on an inner peripheral wall of a steel shell.SOLUTION: A dismantling method of a furnace body related to the present invention comprises: a support pin installation step of installing support pins by determining a cutting position C for cutting a blast mixer 1 into multiple pieces in a height direction, providing through-holes 7 at predetermined intervals in a lower end circumferential direction of upper side blocks to be cut and inserting the support pins 9 for supporting bricks 5 into the through-holes 7; a connecting tool mounting step of mounting strong backs 11 for connecting blocks being upper and lower pieces after cutting; a cutting step of integrally cutting a steel shell 3 and the bricks 5 at the determined cutting position C; a block carrying-out step of removing the strong backs 11 and independently carrying out the blocks to be carried out to predetermined places; and a brick dismantling step of dismantling the bricks 5 of each block by a heavy machine.SELECTED DRAWING: Figure 1 【課題】鉄皮の内周壁に煉瓦を積層した炉体を解体する場合において、炉体を切断して分割して搬送する際に、内部の煉瓦の脱落を防止できる炉体の解体方法を提供する。【解決手段】本発明に係る炉体の解体方法は、ブラストミキサー１を高さ方向で複数に切断する位置Ｃを決定し、切断される上側のブロックの下端周方向に所定の間隔で貫通孔７を設けて貫通孔７に煉瓦５を支持するための支持ピン９を挿入して設置する支持ピン設置工程と、切断後の上下となるブロック同士を連結するストロングバック１１を取り付ける連結具取付工程と、決定された切断位置Ｃにおいて、鉄皮３と煉瓦５を一体的に切断する切断工程と、ストロングバック１１を外して搬出対象となるブロックを個別に所定の位置まで搬出するブロック搬出工程と、各ブロックの煉瓦５を重機で解体する煉瓦解体工程とを備えたことを特徴とするものである。【選択図】図１
