Intelligent identification method of metallurgical mine phase

Abstract

The invention relates to a metallurgy mineralography intelligent recognize method, which uses a mineralography microscope, a camera, an image pickup card and a computer system. And the method comprises that extracting the reflective index and mineralography texture character of known sintered mineralography, to build a database of mineralography character, picking up the mineralography picture of object sample, extracting reflective index and mineralography texture character, using the computer system to recognize the mineralography of object sample, to be compared with the database, to find minimum spatial value, to judge the kind of mine. The invention has simple operation, low labor strength, simple and quick process, and accurate result.

Description

technical field [0001] The invention relates to an intelligent mineral phase identification method in the detection process of sintered ore, pellet ore, blast furnace slag and the like by using a mineral phase microscope in the field of metallurgy. Background technique [0002] At present, the detection process of mineral phases such as sinter, pellets and blast furnace slag in the metallurgical field is mainly completed manually. Especially for the identification of mineral phases in sinter, the operator observes the morphology of minerals in the field of view of the microscope, and then obtains the law of mineral morphology based on the previous summarization and research, and finally draws the Type and content of minerals. Therefore, the operator's experience and skill level determine the accuracy of the experimental results. Moreover, once the sintering production process or raw materials change greatly, it is difficult to guarantee the accuracy of the manual identific...

Problems solved by technology

Moreover, once the sintering production process or raw materials change greatly, it is difficult to guarantee the accuracy of the manual identification results.

Chinese patent application 200610012897.5 discloses "Pellet mineral phase identification method and the rotating device used in the method". The organizational structure data of pellets, and then reflect the factors that affect the performance of pellets according to the data, although it can provide accurate information for the quality evaluation of pellets in a targeted manner, and provide a rich reference for improving the quality of pellets on site, but Unable to identify mineral facies

In addition, since the whole experimental process of sintered ore from sampling, sample preparation to observation under the microscope is complicated and labor-intensive, the cultivation of excellent mineral phase experimenters requires long-term practice no matter in iron and steel enterprises or scientific research institutions experience and learning

Moreover, there are differences in identification results due to individual differences

[0003] Chinese patent application 200610114146.4 discloses the "method for automatic identification and quantification of main minerals in high alkalinity sintered ore", although it can quickly and automatically identify the types and contents of minerals in sintered ore, but there are the following problems: First, due to the use of X-ray diffraction Second, this method cannot distinguish between primary ore and secondary ore; third, it cannot distinguish the mineral phase distribution and mineral phase size in sintered ore; fourth, for sintered ore The size and distribution of pores in the mine cannot be distinguished
