Hi Chicopee
The plates are 300 micron aluminium, each with a sheet of tissue interleaving of the same size which has a weight of 50 grams/square metre, in order to protect our coating.
There is no furthur gap between the plates, there are simply 1200 of them per stack.

Hi Desertfox
We blow hot air into the ovens at quite a speed, and the differences between each area in the oven is minimal, so I am going to assume all air temps are equal for the time being and the thermal gradient minimal.
As for monitoring stack temperatures, a thermocouple arrangement is...
Thanks DesertFox
I will have a go.
One query though: we have found that wide and low stacks heat up a lot quicker than stacks which are narrower and higher. The assumption for this is that the surface area is a lot more, also the surface area to mass ratio is higher, so the heat has more...
Forgot to mention we heat the stacks by placing 16 of them into an industrial oven and blowing hot air in. As they can't go above the setpoint of 55 degrees, when the first one gets there the air temp lowers to maintain the max stack temp of 55 degrees, then the other stacks slowly get there too.
I work in a manufacturing site in the UK, and our process involves heating stacks of aluminium sheets interleaved with a thin tissue paper at a setpoint for a few days.
Maybe this is a no brainer to you folk, but I am trying to find out the heatup rate for certain sizes of stacks. We have stack...
