The invention provides a method for lowering high-
vanadium-
titanium molten iron blowing desulfurization drossing iron loss. Before desulfurization, the contents of C, Mn, V, Si, S, P, Ti in molten iron and the temperature of the molten iron are controlled;
argon or
nitrogen-
argon mixed gas is adopted as a carrier, and Ca and Mg
powder is adopted as a desulfurizer for blowing desulfurization; and a
slag-modifier is added into the molten iron according to a ratio of 0.3-0.8 kg per
ton of iron for desulfurization. After desulfurization, the
argon or
nitrogen-argon
mixed gas is introduced into the molten iron; drossing is performed until 1 / 4-1 / 3 of slags remain; and then the
slag-modifier is added into the molten iron according to a ratio of 0.2-0.5 kg per
ton of iron, and then drossing is performed until the slags are totally removed. After the slags are totally removed, the molten iron comprises the contents of 3.9-4.5% of C, 0.10-0.33% of Mn, 0.24-0.49% of V, 0.10-0.4% of Si, 0.001-0.004% of S, 0.05-0.16% of P and 0.10-0.30% of Ti, and the temperature of the molten iron is 1240-1320 DEG C. By adopting the method, the
slag status of the desulfurization slags of the molten iron can be greatly improved; the high-
vanadium-
titanium molten iron blowing desulfurization drossing iron loss and steel and iron consumption are effectively reduced; and the
smelting cost of enterprises is lowered.
