Abstract

The invention relates to a method of making assay used for gas analysis in the metal, which belongs to chemistry analysis technical field. The sampling machine comprises a mesa board set on the frame, and the following parts set on the mesa: a main gearbox, a work-piece cooler, a water-tight cover, a chuck, a lathe cutter rack, a vertical carriage, and a horizontal carriage. A turning carriage is set on the main gearbox, and a burnishing device which can wobbling is set on the carriage, and the up-right of the mesa board fits a grinder, the right of the board fits a sample cutting device. The burnishing material can use the silicon-carbide abrasive belt or grinding block or steel file. The procedure comprises turning, burnishing, cutting and deburring, and the sampling machine can integrate said functions to analyze the gas itself, then the operation is rapidly and simply and the sampling time deduces from 30minutes to 3minutes.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis, in particular to a sample making machine for gas analysis in metals and a method for making samples. Background technique [0002] Oxygen, nitrogen and hydrogen are contained in steel, and these gases have adverse effects on the performance of steel materials. Accurate detection of the content of oxygen, nitrogen and hydrogen in steel is of great significance to ensure the quality of steel materials. Gas analysis in iron and steel has strict requirements on the preparation of samples. The national standard GB11261-89 stipulates that "6.1 The sample should be made into a φ4-5mm round bar with a length greater than 30mm, and the finish should be above Ra3.2um (6). 6.2 The surface treatment of the sample should be carried out before the analysis, according to 6.1 The prepared sample is polished with 1058um-211um (120-600 mesh) silicon carbide emery cloth and buckskin at a speed of about ...
