Method for simultaneous determination of multi-element content in high manganese steel

Abstract

The invention provides a method for simultaneous determination of multi-element contents in high manganese steel. Through preparation and treatment of samples, a glow discharge emission spectrometer is used for excitation determination of the samples after spectral tracing and drift correction are carried out. The method for the simultaneous determination of the multi-element contents in the highmanganese steel comprises the following steps that (1) an excitation voltage of the glow discharge emission spectrometer is 1250 V, an excitation current is 45 mA, pre-burning time is 60 s, and integral time is 10 s; (2) the high manganese steel is sampled, specifically, requirements of homogeneous and representative compositions of the samples are met, and the samples do not contain inclusions, cracks, pores, oil stains, dust and oxides; (3) sample preparation of the high manganese steel is carried out, specifically, requirements that both surfaces of a sample are smooth and a sample analysissurface is polished carefully; and (4) the purity and the flow rate of argon for an analysis are ensured. The method for the simultaneous determination of the multi-element contents in the high manganese steel has the advantages of high precision, a low detection limit, a small matrix effect, a wide dynamic range of detection concentration, simultaneous detection of multiple elements, short analysis time, simple sample pretreatment, no pollution to the environment and the like.

Description

technical field [0001] The invention relates to the technical field of chemical composition analysis, in particular to a method for simultaneously measuring multi-element content in high manganese steel. Background technique [0002] High manganese steel has good work hardening properties, and is safe, reliable, wear-resistant and long-lived under high impact loads. For a long time, the detection methods of various elements in high manganese steel are still based on chemical analysis and testing. The existing traditional chemical wet method can only measure the content of single elements in high manganese steel, and the analysis period is long and the operation is cumbersome. The reagents used have certain pollution to the environment; technicians also use some instruments to analyze the element content in high manganese steel, such as the determination of manganese in high manganese steel by direct reading spectrometry or X-ray fluorescence spectrometry; or by inductive cou...

The existing traditional chemical wet method can only measure the content of single elements in high manganese steel, and the analysis period is long and the operation is cumbersome. The reagents used have certain pollution to the environment; technicians also use some instruments to analyze the element content in high manganese steel, such as the determination of manganese in high manganese steel by direct reading spectrometry or X-ray fluorescence spectrometry; or by inductive coupling Plasma emission spectrometry simultaneously measures several elements of silicon, manganese, phosphorus and chromium in high manganese steel; High, manganese and iron form a complex matrix, the interference of the matrix or coexisting elements makes it difficult to perform spectroscopic determination, and it is even more difficult to analyze the trace elements
