KHR-A Portable Quenching Medium Cooling Performance Tester
This quenchometer uses a nickel alloy probe with a built-in thermocouple and adopts a cooling curve test method. Directly measure the cooling rate of the medium. Make an accurate judgment on the cooling performance of the medium. The KHR device has reliable quality. It is an indispensable tool for heat treatment process monitoring in the enterprise quality assurance system. By using the quenchometer, enterprises can effectively improve product quality, extend service life, and meet the needs of various complex applications.

Application:

Parameter:

Patent product number: ZL 2008 2 0069148.0
Advantage
Our company is one of the chairman units of China Heat Treatment Industry Association. This equipment is the first automation product developed and manufactured by our company. We are also the first domestic manufacturer to independently develop and manufacture this equipment.Our company's quenching detectors currently account for 95% of the domestic market share. PetroChina and Sinopec-related subsidiaries as well as many military industrial units and state-owned enterprises are our customers.

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).
Structure

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.
