Zusammenfassung:	According to the present invention, a molten steel desulfurization apparatus comprises: a charging ladle where molten steel is inputted for a desulfurization reaction of the molten steel; a mixer deposited in the molten steel mixing the molten steel to activate the desulfurization reaction of the molten steel; and a heat supply unit supplying heat to the mixer to heat the mixer before the mixer is deposited in the molten steel. Moreover, in accordance to another embodiment of the present invention, provided is a molten steel desulfurization method comprising: an input step of placing the molten steel into the charging ladle for the desulfurization reaction; a heating step of supplying heat to the mixer to heat the mixer to activate the desulfurization reaction of the molten steel; and a mixing step of depositing the heated mixer in the molten steel to mix the molten steel. 본 발명에 따르면, 용선의 탈황 반응을 위하여 상기 용선이 투입되는 장입래들, 상기 용선에 침적되어 상기 용선의 탈황 반응 활성화를 위하여 상기 용선을 교반하는 교반기, 및 상기 교반기가 상기 용선에 침적되기 전, 상기 교반기에 열을 공급하여 상기 교반기를 가열하는 열공급부를 포함하는 것을 특징으로 하는 용선탈황장치가 제공된다. 또한, 본 발명의 다른 실시예에 따르면, 탈황 반응을 위하여 용선을 장입래들에 투입하는 투입단계, 상기 용선의 탈황 반응 활성화를 위한 교반기에 열을 공급하여 가열하는 가열단계, 가열된 상기 교반기를 상기 용선에 침적시켜 상기 용선을 교반하는 교반단계를 포함하는 용선탈황방법이 제공된다.
