Method for increasing temperature of vanadium-titanium sinter mixture

The invention relates to a method for increasing the temperature of a vanadium-titanium sinter mixture, and belongs to the technical field of metallurgical sintering methods. According to the technical scheme, an upper row of steam passing pipelines and a lower row of steam passing pipelines are fixedly arranged on a mixed material falling path, one ends of the steam passing pipelines are connected with a superheated steam pipeline, the other ends of the steam passing pipelines are arranged on the mixed material falling path, outlets right in front of the steam passing pipelines are blocked, steam outlet holes are formed in the lower portions of the steam passing pipelines, and steam enters a falling mixed material layer through the steam outlet holes. The method has the beneficial effects that through heat exchange between steam and materials, the temperature of a sintering mixture is directly increased, temperature drop is reduced, the thickness of an over-wet layer can be effectively reduced, and the pheno
