I have deen doing thinking about building a super plete quentch setup. did anyone know that copper has twice the thermal conducitiy of aluminum. aluminum is (300 K) 237 W·m−1·K−1 and copper is (300 K) 401 W·m−1·K−1. as you can see copper plates coud cool steel twice as fast as aluminum. also you could drill holes through the plate long wase and run water through it so it acts like a small radiator. this could cool the steel super fast, what do you think
 
That would be an expensive set of plate's,sounds really cool though.maybe you can find some old printing press plates or something.
 
when i can find some more al i will be doing it sorta like that and mounting the worksd in a press
for me its not the speed of quench but having the plates back to "ready" faster
i pressed a few blades in a row and boy can the plates heat up fast
 
i found a place that will senn me 24" of copper bar that is 2" x 4" but it would cost me $630 bucks. i think it would be cheeper to collect scraps and melt them down. im going to the scrap yard tomarow and see what i can find.
 
Careful.... Plate quenching with aluminum is now a tried and true process, recommended by many steel producers but more of a good thing is not necessarily better. You could cool them super fast by just dropping them in the liquid nitrogen straight from the oven - and watch (through the visor of your haz mat suit) the blade shatter. The video would sell, but the blade probably wouldn't be too much good. :eek:

Then again, there is a pioneer for all great developments. Keep us posted. :)

Well... collecting, melting, and casting 57+ lbs of copper might be a chore...
drilling lengthwise I can do up to about 12 inches, but not cose, parallel holes.
How about drilling across the 4" dimension? lots of holes, with interconnecting tubes along the length...
 
orr better yet mill the groves on both plates to line up till 1 inch from the plate end then drill and tap for the water piping
if you make it so you bolt 2 halves together you dont worry about drilling
alittle rtv should keep things from leaking
my thoughts are to use my 1 inch thick plates on the botom and a .25 thick topper plate and after last night i think i ll set it up to run hot watter in the plates also for my mycarta making as the spee of set is faster at 90 then it is at 70 and i like it cold in the house like 60 (i dont want to have to wait for a week to use my mycarta)
 
JT,
I hope you're not serious about melting down copper. I work with a LOT of copper and the fumes are EXTREMELY toxic!!! More than zinc more than just about anything aside from maybe arsenic. The average lifespan of a copper worker in Peru is less than 3 years. When I weld coppper I have a special airhood to filter in fresh air. Don't F with it. If you WERE joking, just be careful and wash your hands.

Just blow the heat out with an air compressor. Works for me. :)
