Abstract

본 발명은 부정형 내화물 시공체의 골재편재 발생방지 방법에 관한 것으로, 보다 상세히는 티밍래들 바닥에 사용되는 알루미나 스피넬질(Alumina spinel)캐스터블(Castable)내화물의 시공시 내부골재의 편재 발생 방지 방법에 관한 것이다. 본 발명은 대형골재를 사용하는 부정형 내화물의 시공에 있어서 골재 편재를 방지하여 입도분포가 고른 시공체를 얻을 목적으로 서로 다른 입도 분포를 갖는 두 재질(부정형 내화물)을 상,하로 시공하여 바이브레이팅 작업을 통해 고른 입도 분포를 갖는 하나의 시공체를 얻을 수 있는 부정형 내화물 시공체의 골재 편재 발생 방지방법을 제공한다.The present invention relates to a method for preventing the formation of aggregates in an amorphous refractory body, and more particularly, a method for preventing the occurrence of local aggregates during construction of alumina spinel castable refractories used in the bottom of the timing ladle. It is about. The present invention vibrating work by constructing two materials (non-refractory refractory) having a different particle size distribution up and down in order to prevent the aggregate ubiquitous in the construction of the irregular refractory using a large aggregate to obtain a uniform particle size distribution Through the present invention provides a method for preventing the occurrence of aggregate ubiquitous irregular shape of the refractory body to obtain a single body having a uniform particle size distribution.
