Abstract
본 발명은 염기성 캐스타블 내화조성물에 관한 것으로, 청정강 제조에 유리하며 내소화성, 내침식성, 내스폴링성 및 작업성이 우수한 초미분 결합 저시멘트의 염기성 캐스타블 내화조성물을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a basic castable refractory composition, and to provide a basic castable refractory composition of ultra finely bonded low cement having excellent fire resistance, erosion resistance, spalling resistance and workability, which is advantageous for producing clean steel. The purpose is.
상기한 목적을 달성하기 위한 본 발명은 중량%로, 오토클레이브 소화시험법(3㎏/㎠, 2시간유지)에 의한 중량 증가율이 2.0중량% 이하이며, CaO함량이 55중량% 이상인 내소화성 돌로마이트 클링커 : 35∼60중량%, 입경 1㎛ 이하의 초미분 실리카 2∼6중량%, 3CaO SiO(Alite)를 65중량% 이상 함유하는 칼슘 실리케이트계 시멘트 결합재 : 2∼6중량%, 및 나머지 CaO를 40∼53mol% 함유한 입경 1㎜ 이하의 칼슘 지르코네이트 클링커로 조성됨을 특징으로 하는 염기성 캐스타블 내화조성물에 관한 것을 그 요지로 한다.The present invention for achieving the above object is a weight percent, the weight increase rate by the autoclave digestion test method (3 kg / ㎠, maintained for 2 hours) is 2.0% by weight or less, CaO content 55% by weight or more fire-resistant dolomite Clinker: 35 to 60% by weight, 2 to 6% by weight ultrafine silica having a particle diameter of 1 μm or less, calcium silicate-based cement binder containing 65% by weight or more of 3CaO SiO (Alite): 2 to 6% by weight and the remaining CaO The present invention relates to a basic castable refractory composition characterized by being composed of a calcium zirconate clinker having a particle diameter of 1 mm or less containing 40 to 53 mol%.
