1Product Introduction

End quenching test is a standard method for determining the quenching ability of a certain metal or alloy material. This device meets the standardsGB/T225 and ASTM A 255, DIN 50191, ISO 642 "End quenching test method for steel hardenability.”

IIExperimental principle

The principle of end quenching test is: according toHRC (or HV30) hardness scale, starting from the quenched end of the end quenched specimen, tests the hardness values of multiple points at certain intervals along the axis direction. Mark the positions of each measurement result in a coordinate system with hardness values on the y-axis and distance on the x-axis, connect the points, and draw a continuous curve.

4Features of the equipment

1. The measurement methods for the hardenability curve of up to 6 end quenched specimens can be automatically measured at once, including general hardenability steel and low hardenability steel;
2. The hardness tester is a digital Rockwell hardness tester that can be used separately and independently from the automatic system;
3. Automatically generate customized inspection reports and draw the hardenability curve of the sample.
4. Equipped with electronic electric loading sensors and a unique closed-loop control system.
5. The Z-axis of the workbench automatically rises and falls, and the X-axis and Y-axis directions of the sample table automatically move.
6. Press the start button, and the workbench will automatically rise. The sample will automatically load and unload when it touches the pressure head, and the hardness value will be displayed automatically.
7. Touch screen interface, easy to operate, directly select the hardness scale, and the force value will automatically change in the test parameters.
8. According to the standard hardness block, automatically correct each hardness scale into three sections: high, medium, and low.
9. The test force can be automatically corrected by a standard force gauge.
10. It can save the set coordinate points for fully automatic end quenching tests, batch testing, and greatly improve efficiency.
11. Various fixtures can be customized for batch testing of different samples.
12. The data processing function is powerful, including the conversion of various hardness standards such as HR, HB, HV, setting the qualified range, automatic alarm for exceeding the limit, and the ability to input information such as tester and sample name.
13. More sample and experimental information, measurement data saved in EXCEL format on a USB drive for easy editing and processing.
