Titanium-containing molten iron converter dephosphorization method

The invention provides a titanium-containing molten iron converter dephosphorization method, which comprises the following steps of obtaining the Nth converter slag; wherein in the Nth converter slag,the mass fraction of FeO is 15-25%; mixing the converter slag of the Nth converter, titanium-containing molten iron to be smelted and scrap steel, and top-blown oxygen at the flow rate of 2.95-3.35 Nm < 3 >/min/t is used to carry out first-stage smelting to obtain smelted molten steel; and the flow of top-blown oxygen of the smelted molten steel is increased to a target value, conducting second-stage smelting, obtaining the converter slag of the N+1th converter and dephosphorized molten steel, and N is a positive integer. By adopting the method provided by the invention, the dephosphorizationrate of the titanium-containing molten iron can reach 80.31-90.70%, and the iron content of the converter slag at the smelting end point of the converter is obviously reduced. 本发明提供了一种含钛铁水转炉脱磷的方法，所述方法包括，获得第N炉转炉渣；所述第N炉转炉渣中，FeO
