Abstract

The invention provides a method for identifying a silicate phase in vanadium-titanium sintered ore, and relates to the technical field of phase identification. According to the method, vanadium-titanium ore is pretreated and is then finely polished, so that a sheet sample is prepared; the phase in the sintered ore can be uniformly, conveniently, efficiently and accurately identified by identifyingthe color and crystal form of the sheet sample and measuring the contents of all elements of the silicate phase, so that the reliability of the measured data is ensured; after the types and structures of the main metal minerals in the vanadium-titanium sintered ore are figured out, a technical support is provided for the later evaluation of the metallurgical properties of the vanadium-titanium sintered ore, so that sintering and blast furnace production can be adjusted according to the composition, structure and embedding characteristics of the phase in the sintered ore as well as the metallurgical properties of the vanadium-titanium sintered ore; therefore, the method has important theoretical guiding significance for reducing solid fuel consumption, improving sintered ore strength and reducing blast furnace comprehensive coke ratio, and can be applied to inspection and research institutes of various laboratories and production sites.

Description

technical field [0001] The invention relates to the technical field of phase identification, and in particular to a method for identifying the phase of silicate in vanadium-titanium sintered ore. Background technique [0002] With the development of the iron and steel industry and the advancement of iron ore beneficiation and sintering technology, the sintering production of vanadium-titanium magnetite has gone through three stages: low alkalinity, low iron and high silicon sintering, ordinary high alkalinity sintering, high alkalinity, high iron and low Silicon sintering. Panzhihua Iron and Steel currently adopts stage grinding to improve the grade of vanadium-titanium magnetite from about 51.0% in the past to about 54.5%, and SiO 2 The content was also reduced from around 5.0% to around 3.0%. Later, by increasing the amount of high-rich ore and reducing the ratio of vanadium-titanium magnetite, the grade of sintered ore increased year by year, and the SiO 2 As the conte...
