Good speeds for annealing steel/alloy/aluminium?
Good speeds for annealing steel/alloy/aluminium?
(OP)
Hi!
What is a very high speed for annealing low carbon steel, high grade steel, stainless steel div. alloys, aluminium, ...etc
Is 100f/min for a AWG 20 NiCr alloy high ? Elongation ~ 40%
Is 100f/min for a AWG 2 copper wire high ? Elongation ~50 %
Is 1000f/min for a AWG 20 aluminium wire high ? Elongation ~20 %
Please give me some inforamtion about high speeds for a annealing process!
Thanks for your help!

RE: Good speeds for annealing steel/alloy/aluminium?
Are you talking about continuous anneal lines, box anneal or what?
RE: Good speeds for annealing steel/alloy/aluminium?
The annealer tube is aprox. 2m long, so the the alloy is about 7sec in the tube. Annealing temperatur is ~1100°C
So, what to you think about this ?
RE: Good speeds for annealing steel/alloy/aluminium?
I don't think I can calculate what the maximum speed to anneal these wires would be for your setup. It's really more of a heat transfer problem that a materials problem.
You want to hit the recrystallization temperature at the center line of the wire as it exits the furnace.
Somebody like TVP can probably calculate that, but I would use trial and error.
Once you look up the annealing temperature for each alloy you may want to shot the temperature of the wire as it exits the furnace and adjust speed downward until you're just hitting the temperature you need.
