Quench Oil Replacement
Quench Oil Replacement
(OP)
Hi,
I am new at my job and in charge of the quench oil. We got it tested this spring and it looks like it is at the end of its life. We have 2500 gallons total. The last time all of the oil was replaced was in 2006 and it was reconditioned in 2009. I am looking for advice on what to do. Can this oil be reconditioned again? How often should the oil be tested and when should oil be replaced or reconditioned? The oil is used maybe 4 times every 2-3 months. I have the test results and can upload them if they will help.
Thanks.

If the speed is low the oil supplier may have an accelerator chemical that you can add. Sometimes a centrifuge can be used to clean up the oil. Viscosity if too high can cause testing problems. When my oil got to the point where it could not be tested due to viscosity I would get rid of it.
The AIAG CQI-9 Heat Treat System Assessment (Process Table A) guidelines call out quarterly testing at a minimum for water content, suspended solids, viscosity, cooling curve, total acid, and flash point.

The only problem I see is if you are subject to ISO or CQI-9 audits and what is contained in your control plan about reacting to results such as this. My supplier does not put specs on their report, they only make comments such as "add xxx if metallurgical properties cannot be obtained" if a parameter is outside of their range. As long as you can document through metallurgical test that your product meets specs, and that there are no internal or customer specs telling you how to handle your oil, I would leave it alone.
