Abstract

The invention discloses a rapid analysis method suitable for aluminum, iron and silicon content in an aluminum iron alloy, and relates to the technical field of aluminum iron alloy component analysis.The method comprises the following steps of: treating a sample to be analyzed; performing wall build-up treatment in a crucible; uniformly mixing the sample to be analyzed, barium peroxide and lithium carbonate, spreading the mixture in the crucible, and adding lithium metaborate for covering the surface; performing pre-oxidization, adding a demolding agent for fusing, and cooling to obtain a glass-like sample sheet to be analyzed; selecting high-purity aluminum powder, pure iron and high-purity oxide SiO2 to prepare a series of calibration samples, and preparing a calibration sample sheet according to the previous steps; determining the spectral line intensity of aluminum, iron and silicon in the calibration sample sheet with an X-ray fluorescence spectrometer, and establishing working curves of aluminum, iron and silicon according to the measurement result; determining the fluorescence intensity of the sample sheet to be analyzed according to the working curves to obtain the contentof aluminum, iron and silicon in the sample sheet to be analyzed. By adopting the method, the problems of complex flow and low efficiency in the existing chemical component determination method for the aluminum iron alloy are solved.

Description

technical field [0001] The invention relates to the technical field of composition analysis of aluminum-iron alloys, in particular to a rapid analysis method suitable for the contents of aluminum, iron and silicon in the aluminum-iron alloys. Background technique [0002] Aluminum-iron alloys are necessary raw materials for steelmaking production in iron and steel enterprises. At present, for the determination of various elements of this alloy, no national or industry standard analysis method has been formulated so far, and the traditional chemical wet method is still used for component analysis. The traditional chemical wet method has disadvantages such as cumbersome operation and long process. Currently, there is no commercially available aluminum-iron alloy reference material, and each element is analyzed independently, and the analysis period is as long as 20 hours or more. Therefore, it is urgent to find a more accurate and simple instrument analysis method to complete...
