Abstract

본 발명은 래들내에 담겨져 있는 실리콘 탈산강용 온도강하를 저감하기 위하여 슬래그상부에 투입되는 래들 단열보온재에 관한 것으로써, 보온력은 물론 실리콘 탈산강 슬래그의 알루미나 흡수능 및 마그네시아질 내화물에 대한 내침식성이 우수한 실리콘 탈산강용 래들단열보온재를 제공하고자 하는데, 그 목적이 있다.The present invention relates to a ladle thermal insulation insulating material put on the slag in order to reduce the temperature drop for the silicon deoxidized steel contained in the ladle, it is excellent in thermal insulation, silicon alumina slag alumina absorption capacity and excellent corrosion resistance to magnesia-like refractory It is to provide a ladle insulation thermal insulation for deoxidation steel, the purpose is.

본 발명은 슬래그 접촉부위의 내화물이 마그네시아질 내화물로 이루어진 래들내에 담겨져 있는 실리콘 탈산 용강의 온도강하를 저감하기 위하여 투입되는 래들단열보온재에 있어서, 중량%로 CaO: 35~45%, MgO: 5~10%, Al2O3: 5~10%, SiO2: 15~25%, 탄소: 5~10%, 나머지 바인더 및 기타 불가피하게 함유되는 성분으로 이루어지고, 그리고 염기도(CaO/SiO2)가 1.4~3.0인 것을 특징으로 하는 실리콘 탈산강용 래들단열보온재를 그 요지로 한다.In the present invention, in the ladle insulation insulating material is injected to reduce the temperature drop of the silicon deoxidation molten steel contained in the ladle made of magnesia refractory material of the slag contact portion, by weight% CaO: 35 ~ 45%, MgO: 5 ~ 10%, Al 2 O 3 : 5-10%, SiO 2 : 15-25%, Carbon: 5-10%, consisting of the remaining binders and other inevitable components, and basicity (CaO / SiO 2 ) The ladle insulation heat insulating material for silicon deoxidation steel characterized by the above-mentioned 1.4-3.0.
