  1. Vesuvius never got back to me, so I just went ahead and used the stuff. I mixed it with as little water as I could get away with and packed it in by hand. Seems to have worked about like one would expect any castable to work in this sort of application. It does seem to have more aggregate than I would have expected, so its not a smooth finish. I may sift some and do another thin layer on the bottom to smooth things out a bit before I fire it. But, I plan on using some bricks in the bottom to take up some volume, so it may not matter anyway. Its been curing for close to a week. I've really no idea what type of heat schedule to use, so I guess I'll just wing it and hope for the best.
  2. I have 10-15 lbs of it. I know the tundish boxes are fired within one day after being sprayed with the stuff, so I'm not sure about needing moisture, or how much, or for how long. The guys that use it just dump super sacks into a huge automated mixer (Rented from and programmed by Vesuvius) that adds the appropriate amount of water and mixes it itself, so they really can't tell me much of anything useful.
  3. Just to give a bit more backgroud, the product in question is used to line tundish boxes in the steel making process. A tundish box is a large container with nozzles that is suspended above a caster. The box is filled with molten steel, and delivers the molten steel to the casting equipment via the ceramic nozzles. The refractory is usually mixed with automated equipment and sprayed onto the interior panels of the tundish box, similar to gunning.
  4. I haven't heard back from Vesuvius, but I did get hold of an SDS. The listed ingredients are: Chemical Name CAS Number % Range Aluminosilicate 1302-93-8 65.00 - 75.00% Aluminum Oxide, Non-fibrous 1344-28-1 15.00 - 25.00% Cement, Calcium Aluminate 65997-16-2 3.00 - 7.00% Silica Fume 69012-64-2 3.00 - 7.00% Cristobalite, Crystalline Silca 14464-46-1 0.10 - 3.00%
  5. I got it for free. Basically leftovers someone had from some other process.
  6. LOL Yes, Georgia, USA. I've clarified that now in my profile. Thanks. I emailed Vesuvius, and if/when they reply, I'll post it here.
  7. 10-4. I'll take care that. I live near Atlanta, in NW GA. I haven't been able to locate the MSDS yet either.
  8. Hi. I'm working on a forge that will be insulated with Kaowool. I have a product made by Vesuvius called Ultra Max. It is intended to be used as a Tundish liner, and the short description given on the website is as follows: "ULTRA MAX* ultralow cement castable with exceptional alkali resistance, high strength and excellent thermal shock resistance" I plan to use it to coat the Kaowool, but don't really have any instructions on how to use it, fire it, etc. Would I just mix it with water and trowel it onto the surface of the Kaowool like any other castable? I'm guessing that it probably is just that simple, but this stuff is meant to be sprayed onto the inside of tundish boxes and I just wanted to make sure that it didn't need to be applied in several thin coats in order to dry/cure properly. Has anyone used this type of product for lining a forge over top of a ceramic blanket material? Any input will be appreciated. Thanks.
