Fusion sample preparation method for X-ray fluorescence analysis of element contents of silicon and phosphorus in silicon-manganese ball alloy

Abstract

The invention discloses a fusion sample preparation method for X-ray fluorescence analysis of element contents of silicon and phosphorus in silicon-manganese ball alloy. The method includes steps: (1) weighing a mixed flux, and spreading out in a platinum yellow crucible; (2) weighing an oxidant fluxing agent, and centralizing in the middle of the surface of the mixed flux in the platinum yellow crucible at the step (1); (3) weighing a silicon-manganese ball sample, and putting above the oxidant fluxing agent, obtained at the step (2), in the platinum yellow crucible; (4) stirring the sample, obtained at the step (3) in the platinum yellow crucible, and well mixing; (5) dropwise adding a release agent into the sample obtained at the step (4), fusing the platinum yellow crucible and the sample into a sample melting furnace, taking out, and completely cooling fuse pieces to obtain glass fuse pieces of the silicon-manganese ball alloy. The method has advantages of operation simplification, analysis cost reduction, labor intensity relief and test efficiency improvement, and the problem of test result instability caused by a grain size effect and a mineral effect of a pelleting-fluorescence analysis method is solved.

Description

Technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a fusion sample preparation method for X-ray fluorescence analysis of the content of silicon and phosphorus in a silicomanganese spherical alloy. Background technique [0002] Silico-manganese alloy is an important alloy in the steelmaking process. The current inspection method is mainly the national standard method, that is, wet analysis. The analysis result is stable, but the operation steps are complicated and cumbersome, and each element is analyzed independently, and the analysis cycle is as long as 8 hours. . In order to shorten the inspection cycle, some companies have developed tablet-fluorescence analysis, but this method is affected by the particle size effect and mineral effect, which makes the inspection results unstable. [0003] With the development of the metallurgical industry, a new type of alloy appears: composite silico-manganese balls. Due to the dif...
