In an actual lining, even a little water highly restricted can develop pressures that exceed the strength of the refractory material resulting in significant damage from explosive spalling.

Form material question with refractory - Beginners Place

Aug 15, 2021· Then it hit me maybe i could use this cardboard mockup as a form for the castable refractory. The only thing i was thinking is that it could possibly distort with the weight and water of the refractory. I could line it with something to take care of the water. I did some searching and could not really find any answers, probably for good reason.
