Title (EN) JIG FOR CASTING AND CASTING METHOD USING SAME
(FR) GABARIT DE COULÉE ET PROCÉDÉ DE COULÉE L'UTILISANT
(KO) 주조용 치구 및 이를 이용한 주조방법
Abstract:
(EN) The present invention relates to a jig for casting and a casting method using same, the casting method comprising the steps of: injecting molten steel into a mold; supplying mold flux to the upper part of the molten steel; by inserting a jig comprising a refractory into the upper part of the molten steel, having at least one section of the jig make contact with the molten steel and at least one section make contact with the mold flux; and casting a slab by coagulating the molten steel, wherein, in the step of casting a slab, by using the jig, the area of the molten steel making contact with the mold flux may be made to be smaller than the area of the molten steel surface in the mold, and thus degeneration of the mold flux may be inhibited, thereby enabling the improvement of the quality and productivity of the slab.
(FR) La présente invention concerne un gabarit de coulée et un procédé de coulée l'utilisant, le procédé de coulée comprenant les étapes consistant : à injecter de l'acier fondu dans un moule ; à fournir du flux de moule à la partie supérieure de l'acier fondu ; à insérer un gabarit comprenant un matériau réfractaire dans la partie supérieure de l'acier fondu, une section au moins du gabarit étant en contact avec l'acier fondu et une section au moins étant en contact avec le flux de moule ; et à couler une brame par coagulation de l'acier fondu. Lors de l'étape de coulée de la brame, l'emploi du gabarit permet de faire en sorte que la surface de l'acier fondu entrant en contact avec le flux du moule soit plus petite que la surface de la surface de l'acier fondu dans le moule, ce qui permet d'éviter la dégradation du flux du moule et d'améliorer la qualité et la productivité des brames.
(KO) 본 발명은 주조용 치구 및 이를 이용한 주조방법에 관한 것으로, 몰드에 용강을 주입하는 과정; 상기 용강 상부에 몰드 플럭스를 공급하는 과정; 상기 용강 상부에 내화물을 포함하는 치구를 투입하여 상기 치구의 적어도 일부를 상기 용강에 접촉시키고 적어도 일부는 상기 몰드 플럭스에 접촉시키는 과정; 및 상기 용강을 응고시켜 주편을 주조하는 과정;을 포함하고, 상기 주편을 주조하는 과정에서 상기 치구를 이용하여 상기 몰드 플럭스와 접촉하는 용강의 면적을 상기 몰드 내 용강의 탕면 면적보다 작게 하여, 몰드 플럭스의 변성을 억제하여 주편의 품질 및 생산성을 향상시킬 수 있다.
