Title (EN) CONTINUOUS CASTING ABNORMALITY PREDICTION DEVICE
(FR) DISPOSITIF DE PRÉDICTION D'ANOMALIE DE COULÉE CONTINUE
(KO) 연속주조 이상 예측 장치
Abstract:
(EN) A continuous casting abnormality prediction device is disclosed. The continuous casting abnormality prediction device according to one embodiment of the present invention comprises: a temperature sensing unit having a plurality of thermocouples arranged at intervals in a mold receiving molten steel inside a tundish through a submerged entry nozzle; and a control unit for determining submerged entry nozzle damage and/or a slab defect, which includes at least one of mold slag mixing, a slab surface longitudinal crack, and a slab surface transverse crack, by using temperature values sensed from the plurality of thermocouples while a continuous cast process is performed.
(FR) L'invention concerne un dispositif de prédiction d'anomalie de coulée continue. Le dispositif de prédiction d'anomalie de coulée continue selon un mode de réalisation de la présente invention comprend : une unité de détection de température ayant une pluralité de thermocouples disposés à intervalles dans un moule recevant de l'acier fondu à l'intérieur d'un panier de coulée par l'intermédiaire d'une buse d'entrée immergée ; et une unité de commande pour déterminer un endommagement de la buse d'entrée immergée et/ou un défaut d’ébauche, qui comprend un mélange de laitier de moule, et/ou une fissure longitudinale à la surface de l’ébauche, et/ou une fissure transversale à la surface de l’ébauche, au moyen des valeurs de température détectées à partir de la pluralité de thermocouples tandis qu'un processus de coulée continue est effectué.
(KO) 연속주조 이상 예측 장치가 개시된다. 본 발명의 일실시예에 따른 연속주조 이상 예측 장치는 턴디쉬 내의 용강을 침지노즐을 통해 공급받는 몰드에 서로 간격을 두고 배열된 복수의 열전대를 가진 온도감지부 및 연속 주조 공정이 수행되는 동안 복수의 열전대로부터 감지된 온도값들을 이용하여 몰드 슬래그 혼입, 주편 면 세로크랙 및 주편 면 가로크랙 중 적어도 하나를 포함하는 주편 결함과, 침지노즐 파손 중 적어도 하나를 판단하는 제어부를 포함한다.
