| description | The invention discloses a method for recycling desulfurization slag iron by using a converter. The method comprises the following steps that desulfurization slag iron is added into the converter and apart of molten iron is added to perform oxygen blowing and blowing so as to promote the melting of the desulfurization slag iron, and semisteel is formed after the desulfurization slag iron is molten; the semisteel is poured into a molten iron ladle for desulfurization pretreatment, the semisteel and the molten iron are mixed, so that the components of the mixed semisteel are more similar to thecomponents of the molten iron, the components of molten iron subjected to pretreatment and desulfurization are close to that of conventional molten iron, and the molten iron can be directly added intothe converter for utilization. The desulfurization slag iron is added into the converter in the form of waste steel, so that the operation of the converter is kept stable. The temperature rise is carried out by adopting a coke |
