Problems solved by technology

In terms of detection accuracy, the closer the composition and matrix of the spectral standard sample to the substance to be measured, the easier it is to obtain accurate analysis results, especially if the composition of the material is too complex and the content of alloy elements is high, it is easy to form spectral interference , thus affecting the detection results
At present, there is no spectral standard sample for the detection of this steel type. This steel is an alloy steel with high silicon, high manganese, low carbon, low sulfur and other impurity elements. spectral standard

Embodiment 1

[0014] 1. Composition design: iron is the matrix component, the composition and content of alloy elements are shown in Table 1, and the content of other impurity elements are all <0.005wt%.

[0015] 2. Preparation method:

[0016] (1) According to the designed ingredients, 500kg intermediate frequency induction furnace is used for smelting, and induction magnetic stirring is used to ensure uniform composition of molten steel. The deoxidizer is made of pure aluminum, and the φ180mm ingot-shaped metal mold is used for pouring molding;

[0017] (2) The steel ingot is forged after being held at 1100°C-1200°C for 3 hours, forged into a 80mm×80mm×2000mm billet, and air-cooled; then the main elements are segregated, and the results are judged by the range method. -1100℃ for 1 hour, hot rolling into Φ45mm×1000mm round bar;

[0018] (3) The rolled round bars are numbered, descaled, flattened, and processed into Φ40mm×40mm spectral blocks.

[0019] 3. Homogeneity inspection of standar...

Abstract

The invention discloses a standard sample for spectroscopic analysis of a welding wire steel ER50-6, and belongs to the technical fields of new materials and metallurgical analysis. The standard sample is a cylinder the standard of which is phi 40 mm* phi 40mm, and comprises the following constituents: iron serving as a matrix constituent; and alloying element constituents: 0.07-0.09% of C, 0.88-0.92% of Si, 1.45-1.55% of Mn, 0.018-0.022% of P, 0.01-0.015% of S, 0.02-0.03% of Cr, 0.005-0.01% of Ni,0.005-0.01% of Cu, and the contents of other impurity elements are all less than 0.005%. The standard sample has the advantages of good uniformity, exact magnitude and good stability, and is convenient to use; can meet job requirements of a spectrograph such as calibration and test, and provides a good material standard for measuring free cutting steel SAE1215.

Description

technical field [0001] The invention relates to a standard sample for spectral analysis of welding wire steel ER50-6, which belongs to the technical field of new materials and metallurgical analysis. Background technique [0002] ER50-6 is a carbon steel arc welding wire with excellent plasticity, toughness and crack resistance, especially high low temperature impact toughness. It is used for rooting and arc welding of pipes in various positions, and can obtain satisfactory welding joints, and can weld some carbon steel and low alloy steel. In order to strictly control the product quality, the accurate determination of the elemental composition in the steel is of great significance. Composition analysis of alloy steel Iron and steel enterprises mostly use emission spectrometry, and spectroscopic standard samples are inseparable from spectroscopic analysis. In terms of detection accuracy, the closer the composition and matrix of the spectral standard sample to the substance...
