Introduction to instruments for detecting the long-lasting properties of high-temperature creep of metallic materials

GRC-50KN high temperature creep lasting testing machine is a computer-managed measurement and control of the test instrument
.
The testing machine is equipped with a high stability, high-precision servo loading system, which can carry out 300~1200 °C for bar and plate specimens of superalloys, titanium alloys, other ferrous metals and non-ferrous metals, with a test time of no more than 15,000 hours, and a total elongation of not more than 1% of the standard high temperature durable, standard creep test and high temperature tensile, room temperature tension, cycle cycle loading and other tests
.
Stress corrosion test systems
can also be added according to user requirements.
It has the characteristics
of complete functions, intuitive display, convenient maintenance and beautiful shape.
The whole machine is composed
of the main machine, electrical cabinet, and distribution control system.
Executive standard: JJG276-2009 "High temperature creep, durable strength testing machine" GB/T2039-1997 "Metal tensile creep and durable test method" HB5151-1996 "Metal high temperature tensile creep test method" Product features: 1.
The system is controlled in two stages, using high-performance digital intelligent temperature control instruments, each set of direct control system simultaneously controls 5 electric furnaces, each furnace has three temperature control points, and is divided into three sections of temperature
control.
Compatible with a wide range of alloy thermocouples
.
2.
The system is automatically loaded, the required test load and loading speed can be arbitrarily set, the control parameters such as the loading rate are stepless settings, and the control system controls and measures the whole process of the test in real time, and has good anti-interference ability
.
3.
Each direct control system can be controlled online with the host, and can also be operated separately from the host (including the setting and modification of various parameters) and control
.
The color touch LCD screen can display: load, load rate, displacement, deformation (left and right deformation and deformation average), temperature (upper, middle and lower three segments), runtime and program execution content
.
Has : fast up, fast down, slow up, slow down, stop, creep clearance, load clearance, coaxial degree loading and other buttons
.
4.
Automatic heating, heat preservation, loading timing control, automatic cumulative loading test time, automatic temperature control and gradient adjustment, heating rate control, insulation timing control
.
5.
Loading prompt, automatic accumulation of load time, load increase prompt, test end prompt and automatic stop operation
.
Automatic room temperature compensation, automatic channel error and galvey error compensation
.
6.
A variety of alarm and protection functions: with specimen deformation and pull off alarm, thermocouple circuit break and short circuit alarm, temperature beyond the control range alarm and furnace temperature over the upper limit of power off protection, system failure, runaway power failure protection, test end prompt alarm function
.
7.
The display interface is intuitive, the temperature and curve of the three-stage temperature control process are displayed independently, and the cursor positioning data is queried
.
All operations adopt drop-down menu man-machine dialogue mode, easy to operate, and have remote maintenance function
.
8.
A variety of "original record" and "test report" query methods, data can be exported, printed, easy to operate, flexible
.
9.
The system has multi-level user rights management, and cannot be operated
beyond the authority.
10.
The creep deformation measurement method adopts digital grating sensor, which is divided into left and right deformation measurement, and the left and right deformation values can be calibrated and corrected
separately.
11.
The system has perfect temperature calibration and error correction for each temperature measurement point to ensure that the measurement data is accurate
