Application
1, On-site measurement of the cooling characteristics of a quenchant , directly in the quench tank, so as to:
1) Test the cooling performance at various positions in the quench tank;
2) Check the effect of the rate of flow on cooling performance
3) Follow changes in the cooling performance of a quenchant-as a result, for example, of degradation or impurity –over a period of time
2, Laboratory measurement
3, Tests of different quenchant e.g. oils, polymers, water and salt
4, Incoming inspection of quenchants
Mode of operation
A probe containing a thermocouple is heated to the required temperature, normally 850°C, and immersed in the quenchant.
The temperature change is registered on computerized equipment and stored in memory.
All operational process are controlled by CPU system with its touch screen.
For Chinese
For English
After measurement, the temperature and cooling rate and else results are displayed on a flexible LCD touch screen.
Equipment
1,Registration equipment
-Easy-to-use computerized measuring equipment with a flexible LCD touch screen.
-Measurement period:20s,60s,120s,240s,480s,960s,1920s
-Show temperature/time and temperature/cooling rate curves
-Plot curves with date Vmax ,Tvmax ,V300 ,t600 ,t400 and t200
-Stored date may also be displayed in table form
- For making quantitative analysis to the curve, can fold to plot a mesh on the curve
- Can fold four examinations draw as a result on same diagram, for the purpose of analytical contrast
-Cooling data for up to 64 measurements may store in the computer. These remain in memory even after the equipment is turn off
-With RS232C to connect to the another computer, and KHR quenchcurve for Windows computer program for presentation analysis and storage
