Problems solved by technology

[0004] At present, the conventional analysis methods for boron in ferromanganese alloys are mainly methanol distillation-curcumin photometry (GB / T223.75-2008), curcumin direct photometry (GB / T223.78-2008), methylene blue- 1,2-dichloroethane extraction spectrophotometry, but the analysis process of the above method is complicated and the analysis period is long. The pretreatment steps are cumbersome, the analysis cost is high, and it is difficult to meet the production requirements

Abstract

The invention provides a method for detecting a boron element in ferromanganese alloy. The method comprises the steps that S1 a sample solution is prepared; S2 a standard curve is drawn; S3 coexistingelements interference and correction are carried out to determine a standard working curve; S4 the sample is detected, and the sample solution to be detected is introduced into an inductively coupledplasma emission spectrometer through a sampling system to measure the emission spectrum intensity; and S5 according to the standard working curve determined in the step S3, a formula (1) is combinedto calculate the mass percentage concentration of the boron element in the ferromanganese alloy sample. The detection method has the advantages of simple operation and low cost. The accuracy, precision and recovery rate of a detection result are high. The method can meet production requirements.

Description

technical field [0001] The invention relates to the technical field of analysis and detection of ferromanganese alloys, in particular to a detection method of boron element in ferromanganese alloys. Background technique [0002] With the rapid development of the iron and steel industry, high-quality alloy steel has been gradually developed and used. Manganese is one of the most important five basic elements in alloy steel. Adding manganese can significantly improve the strength of steel, improve the wear resistance, hardness and hardness of steel. toughness, etc. The manganese composition in the alloy steel (the average content of the composition is about 1%) is mainly realized by adding ferromanganese alloy, and the ferromanganese alloy can also play the role of desulfurization and deoxidation. Manganese-based ferroalloys (high carbon ferromanganese, medium carbon ferromanganese, low carbon ferromanganese) are abundant in output, accounting for more than half of the total ...
