Method for detecting elements in alloy

Abstract

The invention discloses a method for detecting elements in an alloy. The detecting method comprises the following steps of detecting the content of impurity elements by determining the light intensity ratio through a spectrograph; selecting a standard sample the content of which is closest to the to-be-controlled content numerical value of to-be-determined elements in the alloy; selecting, determining and analyzing a base body, inputting the content of the standard sample into the spectrograph, and setting stimulating parameters; acquiring calculating data, and stimulating the standard sample so as to obtain the light intensity ratio of the standard sample; stimulating a sample sent for detection so as to obtain the light intensity ratio of the sample sent for detection; and comparing the light intensity ratios of the standard sample and the sample sent for detection so as to obtain the detection result. The method provided by the invention is used for detecting the content of the elements in the alloy rapidly and qualitatively, and is especially suitable for on-line detection in a production field.

Description

Technical field [0001] The invention belongs to the technical field of physical and chemical detection, and particularly relates to a rapid qualitative detection method of element content in alloys. Background technique [0002] In the field of physical and chemical testing, it is a common analysis item to analyze whether certain impurity elements in alloys meet the requirements of technical conditions. Direct-reading spectrometer (also called atomic emission spectrometer) is the main instrument of this kind of analysis, using direct-reading spectrometer When detecting element content, the corresponding working curve support is generally required. In the analysis, to determine the size of a certain element in a sample, it is necessary to find the spectral line of the element and compare it with the blackness of the element spectral line in the standard sample. The size is used to determine the content of a certain element. This analysis process takes a long time. Sometimes it is ...

[0002] In the field of physical and chemical testing, it is a relatively common analysis item to analyze whether certain impurity elements in alloys meet the requirements of technical conditions. Direct-reading spectrometer (also known as atomic emission spectrometer) is the main instrument for this analysis. When detecting the content of elements, the corresponding working curve support is generally required. In the analysis, to determine the size of a certain element in a sample, it is necessary to find the spectral line of the element and compare it with the blackness of the spectral line of the element in the standard sample. The size of an element is determined by its size. This analysis process takes a long time. In the production sites of smelting, casting and other fields, sometimes it is only necessary to quickly and qualitatively detect whether an element exceeds the standard, and when the specific element content is not required, the existing analysis method Difficult to achieve
