A flat 24" OD x 2" thk. steel surface is heated to and maintains a 400F temp. on side #1.
On the opposite side (side #2) is a 24"ID x 5" tall x 1/2" thk. steel enclosure. The enclosure has a 1/2" thk. steel cover.
I need to know the estimated temperature inside this steel enclosure.
The ambient temperature surrounding the enclosure is 78F.

RE: Heat
Because of the high thermal conductivity you can assume the back side of the 2" plate will be close to 400deg as an approximation. Are there any fans moving air or strictly gravity convection? Also would need to know surface finishes as these change absorptivity and emissivity.

RE: Heat
The 24"ID x 5" tall X 1/2" thick steel enclosure is welded to side #2 of the heated 2" thk. steel plate. There is stagnant air inside the steel enclosure but there is no airspace between the metal enclosure and the 2" thk. plate. The is a 125 finish on the plates.
RE: Heat
Can you stick a thermometer in there to verify? Empirical data is something to hang your hat on.

Attached is a sketch of the heated enclosure.

No, unfortunately I do not have any software.

RE: Heat
Do you want the highest temperature it can be or the lowest temperature it can be?

RE: Heat
The 2"thick heated plate is steel SA105 (SA105 is the steel used for making "pipe flanges"). The enclosure is made of low carbon steel SA-36.
I am looking for an estimated "high temperature" inside the enclosure.

RE: Heat
I made a mistake on the thickness of the heated plate - it is 2 13/16" thk and not 2" thk.
