Background
The steel material can have hydrogen entering in the preparation, processing and service processes, the hydrogen entering material can reduce the performance of the steel material, various irreversible damages are generated, and serious hydrogen embrittlement can occur to cause great loss. Analysis and investigation of hydrogen requires units of ppm, and conventional hydrogen measurement means have not been able to accurately measure hydrogen content of this magnitude. At present, a reliable means is to use a temperature rising hydrogen determination instrument (TDS), and a quadrupole mass spectrometer is used for determining hydrogen escaping from a material in the temperature rising process, so that the accuracy is as high as 0.01ppm, reversible hydrogen and irreversible hydrogen can be distinguished, and the research on the hydrogen embrittlement of high-strength steel is necessary.
During analysis of the TDS equipment, a sample to be tested is placed at a preset position of a high-temperature quartz tube with the length of 350mm and the inner diameter of 30mm through a sample conveying rod, a heating furnace is started, and a test is started. And for the spherical sample, the sample can roll after being directly put into a quartz tube, if the sample rolls outside the coverage range of a heating furnace, the measurement result can be influenced because the temperature can not reach the requirement, and if the sample rolls outside the control range of a sample transmission rod, the test is ended, and the sample can not be taken out.
Disclosure of utility model

Drawings
FIG. 1 is a schematic diagram of a sample stage of a TDS device for analyzing spherical samples according to an embodiment of the present utility model;
FIG. 2 is a top view of FIG. 1;
in the figure, a sample table body 1, a 2 end cover, a 3 baffle, a 4 opening and 5 samples to be tested are arranged.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1 and 2, a TDS equipment sample stage for analyzing a spherical sample in this embodiment includes a sample stage body 1 of a cylindrical structure, the sample stage body 1 being horizontally arranged. Both ends of the sample table body 1 are open, the inner cavity of the sample table body 1 is used as a sample cavity, one end cover of the sample table body 1 is provided with an end cover 2, and one end of the sample table body 1 is sealed; the sample body 1 other end is as the lofting mouth, and sample 5 to be measured is put in sample body 1 inner chamber through the lofting mouth, sets up the baffle 3 of arc shape on the lofting mouth, baffle 3 periphery and lofting mouth bottom internal diameter phase-match, and baffle 3 highly be 4mm, can prevent that the sample to be measured from rolling to the outside area of sample platform body 1, satisfies the demand of the globular sample lofting that awaits measuring about 6mm again.
An opening 4 with the width of 3mm is formed in the top of the sample table body 1, and the opening 4 is arranged in a penetrating manner along the length direction of the sample table body 1. The opening 4 is rectangular, so that the body balance of the sample table can be improved (the opening part can be automatically positioned at the uppermost side for placement), the random shaking of the sample table body is avoided, and hydrogen molecules released conveniently in the test heating process can escape timely to reach the Q-Mass analysis chamber, so that the normal operation of the heating and hydrogen diffusion process is ensured.
The sample stage body is about 25mm long, the outer diameter is 12mm, and the inner diameter is 10.5mm.
The end cover, the baffle plate and the sample table body are all made of high-temperature resistant quartz materials, and the requirements of a temperature-rising hydrogen determination test are met.
