Method for quickly and jointly measuring various element components in special high-aluminum high-manganese steel by utilizing spark source atomic emission spectrometry

Abstract

The invention relates to a method for quickly and jointly measuring various element components in special high-aluminum high-manganese steel by utilizing spark source atomic emission spectrometry. Themethod comprises the steps of correcting a curve of a spark source atomic emission spectrum, wherein the upper limit of Mn is corrected to 22.5%, the upper limit of Al is corrected to 8.5%, and the upper limit of Ni is corrected to 5.3%; correcting interference among high aluminum (Al), manganese (Mn) and high nickel (Ni) in the curve and interference with elements P, Ti, Pb and As after correction; adopting different spark source atomic emission spectrum analysis curves for staged detection in different stages of smelting, wherein a test sample obtained by a preliminary smelting furnace is analyzed by adopting an uncorrected curve, a test sample obtained by only adding nickel in an electric furnace is analyzed by adopting the the uncorrected curve, and a test sample obtained after alloyis added into a refining furnace is analyzed by adopting the corrected curve. Compared with other detection methods, the method has the advantages of being low in cost, short in time, capable of simultaneously detecting multiple elements, suitable for quick separation detection before special high-aluminum high-manganese steel furnaces are smelted and the like.

[0004] Prior to this, the analytical methods used for the determination of various elemental components in special high-aluminum and high-manganese steels at home and abroad include: molybdenum blue photometry, titration, ICP-MS, and ICP (without spark source atomic emission spectrometry). analysis), the above methods take a long time to analyze and are expensive, and are not suitable for the pre-furnace detection of smelting special high-aluminum and high-manganese steels and cannot meet the needs of simultaneous detection of multiple elements

[0005] To sum up, the detection limit, analysis curve, spectral standard and sample control of the existing spark source atomic emission spectrometry are insufficient, while other detection methods are expensive and take a long time and are not suitable for pre-furnace detection of special high-aluminum high-manganese steel. Due to the problem, spark source atomic emission spectrometry cannot be used to detect various elements in special high aluminum and high manganese steel before furnace
