New Quench Tank, and quenching stuff

[JTknives]

here is my new quench tank. it was going to be a forge but then i relized that it would be to small. so i could not let it get thrown away. it made a perfect quench tank as it has a base to hold it up and it holds lots of oil. Dont ask whats in it as I KNOW I KNOW I KNOWi should be using Parks #50. I just thought i would give this stuff a try and see what it gives me, Just playing around. The same 1095 that will warp and split in half when quenched in water will come out of this stuff straight as an arrow with no cracks and be screaming hard and i mean screaming. I HRC tested a chunk and i got 67RC and i did not even pre heat the oil. The 1095 was heated to 1450 and then held there for allmost 10 min then the temp was bumped up to 1475 for 5 min then it was quenched. it is oil and is very liquid allmost like water or more like diesel at room temp. it sucks the heat out very fast but does not realy flare up as i did not get any flame with quenching a whole blade. got some smoke but not as much compared to my minerial oil. O and yes it is not diesel i'm not that dumb. just thought i would clear that right up. I will countinue to test it out and see how it works.

It's kerosene

Ok. What is it?

looks kinda dark, but I think its canola oil

Whatever it is needs a cover for the tank. Make one today, JT.

I have a piece of steel over it, is that OK or should i have something different. maybe i can find a giant cork . any ideas for a cover. o i could use a small bucket it should just fit over it nicely. OK i will tell you what it is. it is edm oil. it is used in edm etching machines that use a graphite electrode and make stamps and such. it fills the tank up with this and it starts etching the steel by pushing the graphite electrode onto the steel and then using electricity to eat the steel away. so the oil has been designed to cool material very quickly so you don't destroy the heat treat on the steel. also it need to be very fluid to wash away the gunk between the steel and graphite. I works really good. i don't know what its speed is but its fast. its funny because its not really very dark. if you put it in a cup it just has a light brown tint but with that much it adds up. is there a way to test quench speed. like take a steel ball and drill a hole in it and put my temp probe in it. heat up the ball and then quench it and record the time it takes to drop the temp.

Not bad, though I prefer to edge quench, got the bottom tank of a kerosene heater for mine. BTW, that size is fine for a forge, mine rite now isn't much bigger and worked for years with one made from a freon bottle.
