Zusammenfassung:	PURPOSE: A block for filling a blast furnace iron notch is provided to improve the corrosion resistance for an oxygen hole opening process, and to improve the plasticity of a mud material. CONSTITUTION: A block(100) for filling a blast furnace iron notch is in a cylindrical shape formed with a castable material containing alumina and magnesia, to seal an iron notch(10) when opening a blast furnace(1). The castable material contains 85~90wt% of alumina and 10~15wt% of magnesia. The block is divided into two pieces to fit the length of the iron notch. The total length of the block is 3,000~3,500 millimeters. 화입 초기에 산소 개공 작업에 대한 내식성 향상과 머드재 소성능력 향상을 도모할 수 있는 고로 출선구 충전용 블록이 소개된다. 이러한 고로 출선구 충전용 블록(100)은 알루미나(AlO)와 마그네시아(MgO)를 주성분으로 하는 캐스타블(CASTASLE)재로 된 원기둥 형상으로 이루어지는 것을 특징으로 한다.
