Detection method for simultaneously determining contents of multiple elements in galvanized steel and galvanized steel sheets

Abstract

The invention provides a detection method for simultaneously determining contents of multiple elements in galvanized steel and galvanized steel sheets. The detection method is characterized by optimizing the working environment, sampling conditions and sample preparation conditions of a glow discharge atomic emission spectrometer, and simultaneously determining the contents of multiple elements ingalvanized steel and galvanized steel sheets on the basis of establishing a standard curve of each element. The detection method has the advantages of short analysis time, simple sample pretreatment,reduction of the use of chemicals, environmental protection and no pollution in the detection process, and simultaneous determination of the contents of multiple elements, and solves the problems oflong analysis period, tedious operation steps, various reagents and certain pollution to the environment in traditional test methods.

Description

technical field [0001] The invention relates to the field of measuring galvanized sheets, in particular to a detection method for simultaneously measuring multi-element contents in galvanized steel and galvanized steel sheets. Background technique [0002] In order to improve the atmospheric corrosion resistance of steel, galvanizing on the surface of the steel plate is the most effective and economical method. The content of alloying elements, trace elements and impurity elements in the substrate of galvanized steel and galvanized steel sheet directly determines the performance of the material, so its composition analysis is an important basic technology to ensure its material. [0003] The traditional chemical wet method can only determine the content of a single element in steel, which has a long analysis period, cumbersome operation steps, various reagents used, and certain pollution to the environment. Routine determination of each element in steel usually uses inducti...

Problems solved by technology

[0003] The traditional chemical wet method can only determine the content of a single element in steel, which has a long analysis period, cumbersome operation steps, various reagents used, and certain pollution to the environment

Routine determination of each element in steel usually uses inductively coupled plasma emission spectrometer, plasma mass spectrometer, infrared carbon-sulfur meter, etc. Usually, the steel sample needs to be broken into chip-like samples and then acid-dissolved for determination, which can analyze single or several elements in steel. Element content, but it is very rare to determine the content of multiple elements at the same time, which cannot meet the fast-paced requirements of modern steelmaking production

The spark direct reading spectrometer can directly measure the bulk sample without crushing and dissolving the sample, but for the thinner galvanized steel plate, the measurement result is not satisfactory
