Description

Technical Field

[0001] The invention relates to the field of new material testing equipment, and in particular to an auxiliary system and a high temperature testing system for high temperature testing in the form of induction heating. Background Art

[0002] Existing high temperature test systems such as Figure 16-17 As shown, it is generally composed of a high-temperature furnace body 12, a high-temperature furnace control system (testing machine 14) + a high-temperature extensometer / video optical extensometer, a high-temperature fixture structure 11, and a support structure 10. The heating element in the high-temperature furnace body can realize a high-temperature test of the sample under an environment of 1100~1400℃. The reasonable arrangement of the heating element in the furnace realizes a relatively uniform temperature. The high-temperature furnace control system controls the temperature in the furnace. The high-temperature extensometer / video optical extensometer measures the elongation / compression of the sample. The high-temperature fixture structure 11 is used to fix and position the sample. The existing high-temperature test system has the following defects: ① When testing different samples, if the lengths of different samples are different, the test area of ​​the sample may not be in the uniform temperature area of ​​the high-temperature furnace, resulting in inaccurate actual heating temperature. The existing high-temperature furnace test system cannot be fine-tuned and cannot change the position according to the sample size. Replacing different samples requires adjusting the entire system to the appropriate position, which is time-consuming and laborious; ② The specimen is usually not as long as the height of the high-temperature furnace. The temperature in the furnace is too high, so a high-temperature fixture made of a special heat-resistant alloy is required. The high-temperature fixture has a force limit and sometimes cannot meet the test requirements. At the same time, the cost of the high-temperature fixture and the high-temperature furnace is high; ③The high temperature furnace is fully enclosed, leaving only a small observation window, so the real-time status of the sample cannot be seen clearly.
