Has anyone tried to make their own refractory out of metal or metal alloys? I know you can buy a replacement. I also know I can make my own with castable refractory cement. What I would like to explore is the option of a formed metal lower refractory. I picture something that is easy to remove and clean. The brick and cement type refractory are pretty delicate so I don't like moving them any more than I have to. Has this been tried? I know steel or even stainless steel will not last forever because of the heat, but even if they lasted 2 years it may be an attractive option if it were cheap enough. I work at a fabrication/machine shop and we probably have close to 1 million if material inventory so I do not have to worry about getting materials. I also have some inconel or alloy 600 which is very expensive but can take the heat. Just thinking out loud and checking if it is worth trying out.
