Title (EN) CASTING SLIDE GATE
(FR) PORTE COULISSANTE DE COULÉE
(KO) 주조용 슬라이딩 게이트
Abstract:
(EN) The present invention relates to a casting slide gate wherein the region around an opening of the slide gate, which is easy to damage, is formed using a structure containing carbon fibers and carbides highly resistant to thermal shock, and the structure is replaceably connected to a refractory material, so that cracks occurring in the region around the opening can be prevented from spreading to the outer peripheral portion, and when cracks occur in the structure, it is possible to selectively replace only the structure.
(FR) La présente invention concerne une porte coulissante de coulée dans laquelle la région autour d'une ouverture de la porte coulissante, qui est facile à endommager, est formée à l'aide d'une structure contenant des fibres de carbone et des carbures hautement résistants au choc thermique et la structure est reliée de manière remplaçable à un matériau réfractaire, de telle sorte que des fissures se produisant dans la région autour de l'ouverture peuvent ne pas être à même de s'étaler sur la partie périphérique externe et, lorsque des fissures se produisent dans la structure, il est possible de remplacer sélectivement uniquement la structure.
(KO) 본 발명은 주조용 슬라이딩 게이트에 관한 것으로서, 손상되기 쉬운 개구 주변을 열충격에 강한 탄소 섬유와 카바이드를 포함하는 구조체를 이용하여 형성하고, 상기 구조체는 내화물에 교체 가능하도록 연결되어 개구 주변에서 발생하는 크랙이 외주부로 전파되는 것을 방지할 수 있고, 구조체에 크랙이 발생하는 경우 구조체만 선택적으로 교체할 수 있다.
