Embodiment Construction

[0012] The present invention is further described below in conjunction with embodiment:

[0013] A method for establishing a database for identifying origins of imported iron ores comprises the following specific steps:

[0014] 1. Sample preparation method

[0015] According to the standard GB / T10322.1, grind 93 imported iron ore samples until they all pass through a 200-mesh sieve, fully mix the samples and dry them at 105°C, place them in a desiccator and cool them to room temperature for later use; weigh A certain amount of sample is pressed into a sample piece with a semi-automatic hydraulic machine under a pressure of 20t for 30s, and the surface of the sample piece should be checked to be uniform without falling off.

[0016] 2. Analysis method of main chemical components

[0017] Put the sample prepared in step 1 into the X-ray fluorescence spectrometer, measure the set element content to be measured, and store the data in the X-ray fluorescence spectrometer detectio...

Abstract

The invention relates to a method for establishing an identification database of imported iron ore origins, comprising the following steps: 1, grinding and drying an imported iron ore sample and pressing the ground and dried imported iron ore sample into a testing sample piece; 2, placing the testing sample piece into an X-ray fluorescence spectrometer to measure the element content; 3, establishing a database of component contents of the imported iron ore; 4, utilizing a mathematical statistics method to establish a 'digital hologram', determining elements which are most influential to identification and establishing an identification database; and 5, after statistic analysis, determining that five elements including calcium, magnesium, aluminum, copper and vanadium are most influential to identification, simplifying data of the component contents of the imported iron ore, and finally establishing the identification database of the imported iron ore origins. By adopting the identification database of the imported iron ore origins established by the invention, the problem of hard identification of the imported iron ore origins is solved, thus the imported iron ore origins can be identified rapidly and accurately, trade fraud performed by foreign iron ore traders can be prevented and the benefits of domestic users and the country are protected.

Description

technical field [0001] The present invention relates to an identification method for the origin of imported iron ore, in particular to a method for establishing an identification database for the origin of imported iron ore, which is applied to departments such as inspection and quarantine systems, scientific research units, colleges and universities, testing centers and corresponding production plants to identify imported iron ore Origin is identified. Background technique [0002] As the main raw material for steel production, iron ore plays an important role in the national economy. Since the reform and opening up, China's economy has developed rapidly, and the demand for steel has increased year by year. With the rapid development of the iron and steel industry, my country's iron ore output is far from meeting the needs of the iron and steel industry. Due to the high grade and low impurity content of imported iron ore, it has brought significant benefits to my country'...
