摘要(Abstract)：
介绍鞍钢炼铁厂11#高炉大修工程中爆破拆除高炉炉衬的过程．采用爆破方法先破坏炉衬环型砌体结构，再爆破冷却壁之上衬砖，使村砖局部悬空，在重力作用下脱落，达到安全、快速拆除衬砖的目的。
This paper introduces the blasting demolition process of furnace liner during theoverhaul engineering of blasting-furnace No.ll of an iron refinery of Anshan Steel GeneralPlant. FAstly the circle building structure of fUrnace liner was damaged with the method ofblasting. Secondly the lining bricks in freezing wall were damaged so that the lining bricks werehanging sectionally and dropped with the gravity. The intent of safely and speedily demolishingliner bricks was attained.
