Method for analyzing ferrosilicon alloy components for X-ray fluorescence spectrum analysis

Abstract

The invention discloses a method for analyzing ferrosilicon alloy components for X-ray fluorescence spectrum analysis. A method for preparing a sample comprises the following steps of: selecting a proper oxidant; adding a flux into a platinum crucible, putting the platinum crucible in a high temperature furnace, and melting the flux at high temperature to manufacture a wall built-up flux crucible with the basement of flux; mixing a ferrosilicon alloy test sample, the flux and the oxidant, pouring the mixture into the flux crucible, and covering a certain amount of mixed flux; and putting the flux crucible filled with the ferrosilicon alloy test sample, the flux, the oxidant and the mixed flux into the high temperature furnace, preliminarily oxidizing at low temperature, shifting into a high temperature zone, and melting at high temperature to prepare the ferrosilicon alloy test sample glass sample for the X-ray fluorescence spectrum analysis. In the technical scheme, elements are uniformly distributed in the prepared glass sample, and the glass sample has no particle effect and can be preserved for a long time; moreover, the operation method is simple and safe, the preparation time of the sample is short, and primary and secondary quantity elements in the ferrosilicon alloy are rapidly and accurately measured.

Description

technical field [0001] The invention belongs to the technical field of iron and steel industry production, and relates to an analysis method for ferrosilicon alloy components, more specifically, the invention relates to an analysis method for X-ray fluorescence spectrum analysis of ferrosilicon alloy components. Background technique [0002] Ferrosilicon alloy is an alloy of silicon and iron. It is a good deoxidizer and is mainly used in steelmaking and casting as a deoxidizer or an additive for alloying elements. Silica, steel shavings, and coke are the main raw materials for producing ferrosilicon. [0003] At present, chemical analysis is usually used for the analysis of ferrosilicon alloy components. Due to its very high silicon content, sample dissolution procedures are complicated during the experiment, the analysis cycle is long, the labor intensity of analysts is high, the consumption of reagents is large, and the reagents used are easy to cause environmental damage....
