Abstract

본 발명은 용강 주조시 노즐의 내공을 통해서 흐르는 동안 용강중에 현탁되어 있는 알루미나가 노즐 내공의 벽면에 부착되어 노즐 내공의 직경이 감소하거나 폐쇄되는 것을 방지하는 연속 주조용 침지 노즐 내화물의 조성에 관한 것으로, 칼슘지르코네이트 40-90중량%와 흑연 10-60중량%로 이루어진 조성물에 포틀랜드 시멘트 1-40중량%, 규회석 1-15중량%, 프리트(Frit) 1-10중량%중에서 선택한 1종 이상을 첨가하여 조성된 침지 노즐의 내화물에 관한 기술임.The present invention relates to the composition of the continuous casting immersion nozzle refractory to prevent the alumina suspended in the molten steel attached to the wall of the nozzle bore to reduce or close the diameter of the nozzle bore while flowing through the hole of the nozzle during molten steel casting At least one selected from 1-40 wt% of Portland cement, 1-15 wt% of wollastonite, and 1-10 wt% of frit in a composition consisting of 40-90 wt% of calcium zirconate and 10-60 wt% of graphite It is a technique related to the refractory of the immersion nozzle which was added by addition.
