Zusammenfassung:	A method for refining hot metal in a convertor is disclosed. In one embodiment, the method for refining hot metal in a convertor comprises the steps of: pouring hot metal tapped from a blast furnace into a ladle to transfer the hot metal to a kanvara reactor (KR) facility, and introducing a desulfurizing agent to remove sulfur (S); charging the desulfurized hot metal into a pretreatment converter, and removing silicon (Si) from the hot metal by blowing oxygen into the hot metal; tapping the desiliconized hot metal; and charging the tapped hot metal into a decarburizing converter to remove carbon (C). The hot metal poured into the ladle contains 0.6 to 8.0 wt% of silicon (Si). L'invention concerne un procédé d'affinage de métal chaud dans un convertisseur. Dans un mode de réalisation, le procédé d'affinage de métal chaud dans un convertisseur comprend les étapes consistant : à verser du métal chaud soutiré d'un haut-fourneau dans une poche de coulée pour transférer le métal chaud jusqu'à une installation de réacteur Kanvara (KR), et à introduire un agent de désulfuration pour éliminer le soufre (S) ; à charger le métal chaud désulfuré dans un convertisseur de prétraitement et à éliminer le silicium (Si) du métal chaud par soufflage d'oxygène dans le métal chaud ; à soutirer le métal chaud désilicié ; et à charger le métal chaud prélevé dans un convertisseur de décarburation pour éliminer le carbone (C). Le métal chaud versé dans la poche de coulée contient 0,6 à 8,0 % en poids de silicium (Si). 전로에서의 용선 정련 방법에 대한 발명이 개시된다. 한 구체예에서 상기 전로에서의 용선 정련 방법은 고로에서 출선된 용선을 래들에 수선하여 KR 설비로 이동시켜, 탈황제를 투입하여 탈황(S) 처리하는 단계; 상기 탈황 처리된 용선을 예비처리 전로에 장입하고, 산소를 취입하여 용선을 취련하여, 탈실리콘(Si) 처리하는 단계; 상기 탈실리콘 처리된 용선을 출탕하는 단계; 및 상기 출탕된 용선을 탈탄 전로에 장입하여 탈탄(C) 처리하는 단계;를 포함한다. 상기 래들에 수선된 용선은 실리콘(Si): 0.6~8.0 중량%를 포함한다.
