Correct me if I understood order of your dome layers the other way around. Stainless steel casing on inside hot face, ceramic fibre blanket heat insulation, refractory castable. I probably read the picture through the mirror. Firebrick floor cooking surface. Refractory castable will face the heat from the fire absorbing it. Both the firebrick floor and dome will store lots of heat making the atmosphere even. On top of refractory goes heat insulation preventing the heat soaked into dome mass to escape upwards, it absorbs dome expansion also. Casing or some other finishing outside layer. Stainless steel can face the heat and radiate the heat onto cooking meals as firebrick for instance, it needs to have a dense layer behind.
Can the castable be lifted up by a few men? I would need a picture of the structure to give some ideas.
