Abstract

The invention provides an identification method of a metal oxide phase in vanadium-titanium sintered ore and relates to the technical field of phase identification. According to the identification method provided by the embodiment of the invention, vanadium-titanium ore is pre-treated and then is subjected to fine grinding and polishing in sequence to prepare an optical section sample, identify the color and crystal form of the optical section sample and determine the content of phase elements of each metal oxide, so that the identification of the phase in the sintered ore can be uniformly, conveniently, efficiently and accurately carried out; the reliability of determined data is ensured, and types and structures of main metal ore in the vanadium-titanium sintered ore are figured out, sothat technical supports are provided for later-period evaluation of metallurgy performance of the vanadium-titanium sintered ore. Therefore, sintering and blast furnace production can be adjusted according to the composition, structure and embedding properties of the phase in the sintered ore and the metallurgy performance of the vanadium-titanium sintered ore, and the identification method has important theoretical guidance meanings of reducing solid fuel consumption, improving the strength of the sintered ore and reducing indexes including blast furnace comprehensive coke ratio and the like,and can be popularized and applied to inspection of all laboratories and production fields and research institutions.

Description

technical field [0001] The invention relates to the technical field of phase identification, and in particular to an identification method for metal oxide phases 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. In the prior art, stage grinding is currently used 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 content de...
