The invention provides a method for increasing the residual manganese content in molten steel at the end point of a converter. According to the method, the waste steel loading amount of the converteris controlled according to the waste steel ratio of not more than 15%; at the early stage of the smelting, the iron-carbon ball slag is added while the white ash slag is added into the converter, theadding amount of the first batch of the slagging material is 50-70% of the total adding amount, the blowing starting position of the oxygen gun is 0.8-1.2 m, and the gun position is increased to 2.2-2.6 m after blowing is performed for 1-2 min; 25-40% of the remaining slag is added after blowing is performed for 3-6 min; at the middle stage of the smelting, the oxygen gun is lifted to 2.5-3.0 m, blowing is performed for 10-30 s, and then the oxygen gun is lowered to the basic gun position; and at the late stage of the smelting, the gun position is controlled at 1.0-1.2 m, and the remaining slag is added to the converter at 2-5 min before the tapping. According to the present invention, with the method, the residual manganese content in the end point molten steel can be increased, the alloyaddition amount during alloying can be reduced, the steelmaking cost can be reduced, the FeO content in the final slag can be reduced, the converter blow loss can be reduced, and the rephosphorization and the tapping slag discharge can be effectively prevented.
