What is a high temperature tensile testing machine?
The high-temperature tensile testing machine is a professional equipment used to test the mechanical properties of materials such as tension, compression, and bending in high-temperature environments. It is widely used in aerospace, automotive manufacturing, materials science and other fields to help researchers and engineers evaluate the performance of materials under extreme temperature conditions. The following is a detailed introduction to the high temperature tensile testing machine.
1. Basic principles of high temperature tensile testing machine
The high-temperature tensile testing machine raises the test environment to the set temperature through the heating system, and at the same time accurately measures the mechanical properties of the material at high temperature through the sensor and control system. Its main working principles include:
1.heating system: Use electric heating or radiant heating to heat the test area to the target temperature (usually up to 1000°C or above).
2.Mechanical loading system: Driven by hydraulic or motor, apply tensile, compressive or bending load to the specimen.
3.data acquisition system: Record the deformation, load and temperature data of the specimen in real time and generate a test report.
