Metal high temperature durable creep testing machine

High-temperature creep refers to the phenomenon that the material slowly undergoes plastic deformation with the extension of the loading time under the temperature T≥(0.3~0.5)t (t is the melting point, the temperature is T) and the stress far lower than the yield strength.It is used to test the creep properties and durable strength of various metals and alloy materials in high temperature environments to test the creep limit, durable strength limit and other performance parameters of materials.Due to different ways of applying stress, it can be divided into high temperature compression creep, high temperature tensile creep, high temperature bending creep and high temperature torsional creep.High-temperature creep can more effectively predict the strain trend and fracture life of materials when used for a long time at high temperatures than high-temperature strength. It is one of the important mechanical properties of materials. It is related to the material and structural characteristics of the material.

Main features of high temperature durable creep testing machine:
1. The working efficiency of the barrel-type high-temperature furnace is high, which is more than ten times that of the traditional split-type high-temperature furnace. The sample can be replaced and repeated tests are carried out without the need for cooling, heating and insulation processes;
2. The electric system controls the up and down movement of the barrel-type high-temperature furnace, and the linear guide guide ensures safety and stability, and ensures the concentricity of the sample and the furnace;
3. Electric lift-type high-temperature furnace, the operator does not need to touch the high-temperature furnace, which greatly reduces labor intensity and is safe and reliable;
4. The barrel-type high-temperature furnace has good thermal insulation effect, long uniform temperature zone (200mm), high temperature can reach 1200℃, and long service life of the electric furnace. It can be used for 30,000 hours under conditions not higher than 1200℃;
5. The barrel-type high-temperature furnace has good safety performance and is powered by large current under safe voltage (25V). There is no hidden danger of leakage and it complies with international safety standards;
6. The barrel-type high-temperature furnace has a low furnace surface temperature, and imported insulation materials ensure that the furnace surface temperature is lower than 90°C (at 1200°C), making it safe to operate;
7. Adopt fully digital AC servo and high-precision, high-response frequency AC servo motor, with fast frequency response and high positioning accuracy;
8. It has manual unloading adjustment function, which can effectively protect the machine, especially the load sensor, during unexpected power outage.
