Stadelman Furnace refurbish

I have been operating my 300# Stadelman furnace for a little over nine years and it is time for a rebuild. I would like to replace the door arch and all the fibre insulation. We are using Gaffer batch which has eaten the door arch to the point where it needs replacing. This is not a criticism of the batch we are using, at around 400 charges the furnace has held up really well. Will it be possible to cast another door arch and replace the existing one ? The next door I cast will have as big a vent as I can put in it to alleviate future problems. I am hoping to remove the existing arch somehow and replace it. I( have replaced the crucible a couple of times and put in new roof insulation but I have never looked at the insulation in the walls. Is the insulation within the walls blanket or bulk fibre?What should I cast a new door arch with? I have cast new doors from time to time using the same refractory that i used for my glory hole doors and it seems to hold up O.K.

we supply the actual doghouse door but not the door as an original casting if that's what you want. All other parts as well, except for the door.

Tim You are spot on, with a vent built in the door. If you can, line it with a high alumina tube, (sq. or round) it would help, for the long run.

PS My regards to the lovely Tallie.

I used a long one inch thermocouple tube when I did that.

I believe it would have been fiber blanket wrapped around and pinned in place before the round steel exterior went around it.

Mine is two inch thick fiber blanket in multiple wraps and I think it's about 8lb density. Mine is rectangular, not round though.

there were two different castings for that furnace. One long, one short. Do you use a 9/18 312/500 element or a 6/12 450/500 element. The 6/12 is far thinner and turned into a pain to ship so Steve switched to a beefier but shorter element. That in turn changed the castings.

Again. this isn't the actual door. It's the casting that the door rests against.
MaryBeth tells me the long is $444.00 and the short, $406.00 FOB Portland.
