Method for identifying ore phase of sphere blockage mine, and rotator used by the method

Abstract

A pellet mineral phase identification method and a rotating device used in the method belong to the technical field of iron and steel smelting, and are used to solve the problem of unifying the pellet mineral phase identification process with its organizational structure. The special feature is: fix the ore sample on the rotating device, place the rotating device on the microscope stage, rotate the moving part, and carry out identification with one visual threshold at a time, until returning to the initial position to complete a ring of identification, record The ring identification data is divided into rings from inside to outside or from outside to inside in the same way, and the identification data of each ring is recorded. The identification data is classified and counted according to the number of rings. The present invention is a pellet mineral phase survey and identification method designed according to the characteristics of the layered distribution of the pellet structure, which can obtain the pellet structure data with more structural characteristics, and then reflect the factors that affect the performance of the pellets according to the data. Factors, targeted to provide accurate information for pellet quality evaluation, and provide a richer reference for on-site improvement of pellet quality.

Description

technical field [0001] The invention relates to a pellet ore mineral phase identification method and a device used in the method, belonging to the technical field of pellet ore determination. Background technique [0002] Sinter and pellets are the main iron-containing raw materials for blast furnace ironmaking. Their quality will directly affect the stability and energy consumption of blast furnace smelting, and their quality is also related to the composition, properties and relationship between the minerals eventually formed inside. There is a close relationship between the structural characteristics of sinter and pellets, and these characteristics determine the mechanical strength and reduction performance of sinter and pellets. The mineral phase microstructure identification of pellets is one of the important means to evaluate its metallurgical properties. The mineral phase microstructure identification usually refers to the shape, relative size and their mutual combina...

AI Technical Summary

Problems solved by technology

Therefore, the ordinary two-dimensional linear movement method is used for the mineral phase identification of pellets, and the identification process is separated from its organizational structure. The identification results can only be used for overall evaluation of the pellet samples, and cannot be refined by layer and have a good reaction process. process, and cannot intuitively reflect the difference in organizational structure between layers, which is not conducive to the comparison of ore samples in the same period.
