I have a question about heat treating O1 tool steel. In this process the tool is heated, then quenched in oil, meaning the hot tool is plunged into a bath of oil that is normally preheated to about 200 °F. The tool is then transferred to a tempering furnace where it is held at the tempering temperature for a period of time. This transfer is supposed to happen immediately after the quenching has been accomplished.
The problem is that after I quench the tool, it is covered in oil (obviously). If I put the tool into the tempering furnace with oil on it, it can damage the furnace because the oil can be converted to fumes which can contaminate the heating elements in the furnace.
However, if I try to clean the oil off, I have a problem that I am trying to clean a hot object and as I do so, then the tool is cooling down. If it cools below about 150 °F, then I think the heat treatment will be imperfect because in the case of O1 from what I understand you are never supposed to let it get below that temperature during the process.
So, the problem is: How can I get the oil off of the tool without cooling it?
