description The invention relates to a method for prolonging the service life of a high-titanium type blast furnace slag carbonization electric furnace lining and belongs to the technical field of high-titanium type blast furnace slag smelting titanium slag carbonization. The method includes the following steps that a, a carbonaceous reducing agent A and cold state high-titanium type blast furnace slag are mixed evenly according to a certain mass ratio to obtain a mixed material; b, the mixed material obtained in the step a is poured into an electric furnace in the circumferential direction of the inner wall of the electric furnace, the height of the mixed material is H1, and the mass of the mixed material is m1; c, hot state blast furnace slag is added along the axis at the middle portion of an electric furnace, the height of the liquid level of the hot state blast furnace slag is H2, and H2 is not larger than H1; d, the electric furnace is powered on for smelting; and e, a carbonaceous reducingagent D is added, the ele
