Smart Quenching Tester
This tester adopts a nickel alloy probe with built-in thermocouple and a cooling curve test method for detecting the performance of the medium. Directly determining the cooling rate of the medium can more accurately dete


Chemical, boiler, heat exchanger, pressure vessel, pharmaceutical, construction machinery, military and nuclear power industries.


Patented number: ZL 2008 2 0069148.0;
probe length: 600mm;
measured max. cooling rate: 2000 ° C / S.
1. Basic advantages:
a). International standards, easy to integrate with international advanced technology.
b). Directly determine the cooling rate of the medium, more accurately determine the cooling performance of the medium compared to the existing indirect methods.
c). Portable measurement enables dynamic measurement and control of the bath.

2. Functional advantages:
a). The max. cooling rate, the cooling range 300 °C - 600 °C, and its performance of the water-based and oil-based cooling media under field conditions and laboratory standards. 
b). This unit can store 64 test results for retrieval.
c). Four test results can be stacked on the same map for comparative analysis.
d). With communication interface and computer-specific software, the test results can be transmitted to an external computer for further analysis and evaluation.

3. Alternative featured advantages:
a). Special probe used to test the performance of cooling medium, such as high speed steel quenching and stainless steel solid solution.
b). Perform heating and cooling processes, such as induction hardening, heat treatment of large castings and forgings.
c). Determine the cooling medium performance of water-based quenching media under different agitation strengths (Tensi method cooling standard device).

a). The probe is heated to a specified temperature (usually 850 ° C), being inserted into the medium to be tested for cooling, cooling rate is recorded by a built-in microcomputer system, and the detection result is set by a four-color drawing printer. It is plotted as a cooling process curve (temperature/time) and a cooling characteristic curve (temperature/cooling rate). Results can also be printed as a tabular output. Performance of the medium is evaluated based on the above results.

b). Analysis principle:
Comparing the maximum cooling rate of the measured medium with the critical cooling rate of the workpiece determined in advance to determine whether the hardening ability meets the requirements and whether the medium should be replaced or adjusted;

c). The 300 ° C cooling rate of the measured medium is compared with the 300 ° C crack-free safe cooling speed of the workpiece determined in advance to determine the quenching tendency of the medium to the workpiece and whether the medium should be replaced or adjusted; the medium can be determined according to the cooling curve. Lower characteristic temperature.
