Embodiment 1

[0020] Step 1. Select a steel sample with a specification of Φ14mm, and use a wire cutting machine to cut the steel sample with a length of 28mm. When cutting, ensure that the upper and lower intercepting surfaces of the steel sample are parallel;

[0021] Step 2. Place the steel sample cut in step 1 on the plane of the oil cylinder platform under the beam of the WAW-1000 electro-hydraulic servo universal testing machine. The sample is placed in the middle of the platen cross to prevent the sample from tilting or falling. The electro-hydraulic servo universal testing machine carries out the cold upsetting test, and the steel sample is pressed to 14mm, and the nominal cross-sectional diameter of the sample increases to 20.56mm;

[0022] In step 3, use a grinding machine to grind the upper and lower sections of the steel sample obtained in step 2 to obtain a sample that meets the test requirements of the ARL-3460 direct-reading spectrometer.

Embodiment 2

[0024] Step 1. Select a steel sample with a specification of Φ12mm, and use a wire cutting machine to cut the steel sample with a length of 24mm. When cutting, ensure that the upper and lower intercepting surfaces of the steel sample are parallel;

[0025] Step 2. Place the steel sample cut in step 1 on the plane of the oil cylinder platform under the beam of the WAW-1000 electro-hydraulic servo universal testing machine. The sample is placed in the middle of the platen cross to prevent the sample from tilting or falling. The electro-hydraulic servo universal testing machine conducts cold upsetting test, presses the sample to 12mm, and the nominal diameter of the cross-section of the sample increases to 17.22mm;

[0026] In step 3, use a grinding machine to grind the upper and lower sections of the steel sample obtained in step 2 to obtain a sample that meets the test requirements of the ARL-3460 direct-reading spectrometer.

Abstract

The invention discloses a processing method of a small-size steel sample for testing by a direct-reading spectrometer. Particularly, the method comprises steps as follows: firstly, a steel sample with nominal diameter being phi10-phi16 and the length being twice the diameter is cut out by a wire cutting machine; then, a cold upsetting test is performed on the steel sample by a WAW-1000 electro-hydraulic servo universal testing machine, and the sample is compressed into 1 / 2 of the original length, so that upper and lower sections of the sample are increased; finally, the sections of the sample are ground flush by a grinding machine, and accordingly, the sample meeting requirements of the ARL-3460 direct-reading spectrometer can be obtained. The ARL-3460 direct-reading spectrometer is the most widely used spark direct-reading spectrometer in the world at present. With adoption of the processing method, the problem that no reasonable testing methods are available for the samples with nominal diameter of phi10-phi16 for the ARL-3460 direct-reading spectrometer is actually solved, so that the application prospect of the ARL-3460 direct-reading spectrometer is wider.

Description

technical field [0001] The invention belongs to the technical field of steel processing, and in particular relates to a processing method for testing small-sized steel samples with a direct-reading spectrometer. Background technique [0002] ARL-3460 direct-reading spectrometer is the most widely used spark direct-reading spectrometer in the world. It is used to quantitatively determine the concentration of chemical elements in metal samples. It is most suitable for daily production control, quality management and special analysis research. ARL-3460 direct-reading spectrometer not only has new breakthroughs in the analysis of nitrogen content in steel, oxygen content in copper samples and trace elements in non-ferrous metals, but also does not need instrument standardization in the case of continuous analysis. The excitation table hole diameter of ARL-3460 direct reading spectrometer is 15mm. According to the provisions of spark discharge atomic spectrometry (GB / T4336-2016) ...
