Anyone rebuilding this Summer?

[Mark Rosenbaum]

I have some Plastech 90P high alumina ramable that I don't need. I had to buy 55 lbs and I only needed 10. It is good up to 2500 degrees. It only has a 6 month shelf life, so I would rather sell it than let it spoil.
The 44 lbs would normally go for $121 (not including tax and shipping which cost me $35)
I'll let it go for $100......any takers?

Mark could I use that to make the door on the glory hole at the Belmont?


If so just bring it with you to P-cola.

It might be dense for a door....but it would retain the heat....hmmmm, what does anyone else out there think? Would this be a good material for a GH door?

[Scott Novota]

what is it normally for?

We used it to build up the sill of the furnace that was worn away.

I would think a rammable would be hard to get a tight fit on in a door frame. I would think that having keepers in the clay would have to be there to hold it and it would need a lot of insulation. At 100 bucks plus, It would make for an expensive door compared to kast-o-lite 30.

Was this on your electric furnace? Tell me about it?

[Mark Rosenbaum]

Yes, it was my electric. From what I understand, mine had the older castable and the sill in the front wore/melted away. We tried to patch it with some other stuff the last crucible change, but it didn't hold. This ramable looks to be holding a lot better.

[Pete VanderLaan]

I will ask Les at High temp about the history on that. In the early furnaces, Steve used either Flocast fom Pryor Giggy or Morco95lite from Missouri refractories and cast them at home. He switched to High Temp to have them made I think about two years ago.

If you can get it, Missouri refractories MORCO 95 is the best high alumina refractory castable I have ever seen. I don't like the "Lite" at all. Those little alumina air bubbles are just a floating nuisance. Really hard to mix evenly and when ou have, it wasn't worth mixing at all.

here's one from the inside....kinda melted....4 years of service...

[Scott Novota]

4 years. To me that looks pretty good but I have no experience in this area.


How do you feel about it Mark?


I guess it would not work well for a door. Oh well, I will just buy some Kasolite-30 I guess.

Four years? Wow time flies... I think of that being delivered last year. I am quite sure that is one of the original phlocast pieces.

I guess it's more like 3 1/2...we got it after that bitch Katrina paid a visit....

Hi-

I hate to show my lack of knowledge, but why would something like this have a shelf life? Especially such a short one.

I don't know, I think because it is already mixed up with water like a clay. But then, I'm only guessing....

[Pete VanderLaan]

Mark, tell me exactly what it says iss init an I'll ask our trusty in house ceramic engineer at High Temp. They make this stuff.

I'll let you know on Monday when I get back to the studio....

They make these products as "Air set," and Heat set". The air set really can't have any air around it at all. It's relatively cheap for what it is since alumina has been through monthly price changes until recently. Always make sure if you are buying rammables that the ship date is recent. It turns to cinderblocks and is really hard to reconstitute. The grog is like pebbles. I would bet it will last longer than six months but the stuff should be triple bagged with the air sucked out.

Thanks very much. The more I learn, the more questions I have.
