The high-temperature furnace electronic universal testing machine is an advanced material testing equipment that combines an electronic universal testing machine and a high-temperature environment simulation system. It is mainly used to test the mechanical properties of materials (such as tension, compression, bending, creep, fatigue, etc.) in high-temperature environments (usually up to 1200 ℃~1600 ℃).
1. Equipment composition
(1) Electronic universal testing machine part
High precision servo motor drive: provides stable and precise loading control (load range usually 1kN~300kN).
High rigidity frame: double column or door structure to ensure stability during high temperature testing.
Sensor system: Load sensor, measuring the force on the sample with an accuracy of ± 0.5%.
High temperature extensometer: measures the deformation of a specimen at high temperatures (non-contact laser extensometer or high-temperature contact type).
Displacement sensor: records the displacement of the crossbeam.
(2) High temperature furnace system
Heating method:
Resistance heating (MoSi ₂, SiC heating element, up to 1600 ℃).
Induction heating (suitable for rapid heating, but with poor uniformity).
Temperature control:
PID closed-loop control ensures temperature stability (± 1 ℃~± 5 ℃).
Real time monitoring using thermocouples (K-type, S-type, B-type) or infrared thermometers.
Furnace structure:
Double layer insulation design (ceramic fiber+water cooling system) to prevent external overheating.
Removable furnace body (convenient for sample installation).
(3) Data acquisition and control system
Computer control (with supporting professional software such as LabVIEW, TestXpert, etc.).
Real time data recording (stress-strain curve, temperature time curve, etc.).
Safety protection: overload protection, over temperature alarm, emergency stop function.
