Description
Technical field
The utility model relates to metallurgical test equipment, particularly a kind of centering instrument of Measurement accuracy sample maximum temperature in thermal modeling test.
Background technology
Gleeble series of heat/mechanical simulation test machine product that DSI company of the U.S. produces has a wide range of applications in physical simulation field.Gleeble series of heat/power dynamic analog test machine possesses resistive heating system, hydraulic loading system and signal dynamics collection and high-precision servo feedback control system simultaneously.Utilize this equipment can study composition and each technological parameter to the impact of structure and properties, be used to guide the formulation of product design and actual production technique, and contribute to founding mathematical models.The type testing that Gleeble series of heat/mechanical simulation test machine can do comprises list/multi-pass compression deformation test under different temperatures, high temperature thermoplasticity test, phase transition point test, the last zero/low-force test, melts and setting test and the test of HAZ welding analog etc.
Adopt Gleeble series of heat/mechanical simulation test machine can reproduce on the small sample of certain size with actual production, processing, the process in which materials such as to weld certain put almost on all four thermal cycle or Cyclic Stress, and obtain akin tissue and mechanical state, the ultimate principle of Here it is Gleeble series of heat/mechanical simulation test machine.
Thermal simulation experiment process is as follows: centre thermocouple wire being welded in sample, ensures that two thermocouple wire solder joint line directions are vertical with specimen length direction; Then sample is put into fixture, detect by an unaided eye and ensure that thermocouple wire bond pad locations is identical apart from fixture two ends, because in resistance heating process, the temperature in sample centre position is the highest, thermocouple wire can the situation of change of real time record sample maximum temperature; When measuring expansion curve, dilatometer is stuck in the change of real time record sample swell increment on position corresponding to thermopair.
After the above-mentioned experimentation of employing carries out thermal simulation experiment, inconsistent by maximum temperature position sample being analyzed to thermocouple wire bond pad locations and the sample centre usually finding measuring tempeature.This is because the maximum temperature position of sample is apart from the equidistant place of fixture, two ends, and when sample being put into fixture by visual inspection, due to machine intimate limited light, add that the naked eyes of people judge inaccurate, be difficult to ensure that thermocouple wire bond pad locations just only records the temperature of thermocouple wire bond pad locations apart from the equal such system of two ends fixture, and make sample thermocouple wire bond pad locations consistent with the temperature that system sets in real time by FEEDBACK CONTROL, and the real time temperature of sample middle is higher than the temperature of thermocouple wire record, and thermocouple wire bond pad locations differs larger with two fixture centre positions, the temperature deviation recorded is also larger, the sample maximum temperature that this makes system record is forbidden, be difficult to the quantitative analysis being applied to science.
