Abstract

The invention discloses a melting sample preparation method for determining a silicon-aluminum-calcium-iron alloy by using an X-ray fluorescence spectrometry, which utilizes a melting method to replace a chemical method to carry out X-ray fluorescence analysis on a silicon-aluminum-calcium-iron alloy sample, and overcomes the defects of independent determination of each element, long time consumption, low detection efficiency and high analysis cost in the chemical method analysis. The analysis accuracy and precision are effectively improved. According to the method, the analysis efficiency of the silicon-aluminum-calcium alloy is greatly improved, the analysis period is shortened from two days to 60 minutes compared with wet chemical analysis, and meanwhile, the dosage of chemical reagents is reduced, so that green and environment-friendly detection analysis of the silicon-aluminum-calcium alloy is realized. Compared with data analysis, the method meets the detection and analysis quality control requirements, and can be used for controlling and testing the incoming silicon-aluminum-calcium alloy and the production process.

Description

technical field [0001] The application relates to the field of determination of silicon-aluminum-calcium-iron alloys, in particular to a melting sample preparation method for determining silicon-aluminum-calcium-iron alloys by X-ray fluorescence spectrometry. Background technique [0002] Silicon-aluminum-calcium-iron alloy is an alloy composed of silicon, aluminum, calcium, iron and a small amount of carbon and other elements. It is a ferroalloy with wide application and large output. Silicon-aluminum-calcium-iron alloy is a composite deoxidizer commonly used in steelmaking, and its deoxidation effect is remarkable. Si-Al-Ca-Fe alloy is the main raw material for smelting alloy steel and low alloy steel, but the Al produced by the deoxidizer during the deoxidation process 2 o 3 In the form of strips, the toughness and ductility of steel are reduced. At the same time, since Al 2 o 3 With a high melting point, it is easy to block the nozzle during continuous casting and c...
