The refractory is 1650 celsius (centigrade), which according to one online calculator is 3002 farenheit, so I guess you're close enough oldgoaly!
Made some more progress today, so again with some photos:
Got the lid lifting business finished, except for the pedal arrangement- can't do that until I have the base plate sorted and for now I have a temporary plywood base in place for pouring the refractory
I used some of my bolt collection to make a sort of spoke arrangement which I hope will hold the disc of refractory lid from falling out of the ring
The only bit of suitable material that I had on hand for the upright part of the lid lifting arrangement was galvanised RHS, the small amount of gal welding left me with a headache for the rest of the day, horrible stuff. Can't even use a fan for the fumes when using the mig. Serves me right for being too lazy to switch to the stick welder and set up a fan, was such a small amount of gal welding I didn't think it was worth it. Hope this doesn't fume me every time I do a melt with the thing.
Set up the lid frame on some plywood ready to take the refractory, the tin for the exhaust port is sitting over 4 nails to keep it central
A few more tins for plinths
The plan is to cast the refractory tomorrow, I have a promise of help from the wife to lend a hand with holding the formers for the inlet, preheater and tap hole while I ram the refractory up. Left it all set up ready to go (I hope)
If those of you with experience of this stuff spot some problems, please speak up before I start wetting the refractory tomorrow. I'm particularly keen for opinions on whether the bolts poking in from the rim of the lid will be enough to hold the refractory without causing cracks, this seemed like a reasonable way to go but I have not used the stuff before.
