Pre-mixed, fiber-reinforced, high temperature silicate mortarUse where thicker joints are requiredWithstands working temperatures up to 3000-Degree F1/2 Gallon Size, Buff in colorNOT FOR OUTDOOR USE. Made in the USA
I did a similar thing with two steel feed pails. I baked it at 300f for a few hours before I first used it, and it was fine. However, the steel burned out within a few hours of use.
One problem I had, was the wire around the top of the pail expanded when hot, and caused cracking. A thick steel inner liner might cause expansion cracking.
I used this stuff to coat the inside, and it worked wonders. It goes on in thin layers, and I used almost an entire bucket on my furnace, (1 by 1 foot interior) but you could get away with a thinner coat.
I abuse my furnace quite a bit, and it has held up very well. It is also very easy to patch.
Edit: some pics of the furnace
a pic of some of the abuse it went through. .
What if you just use castable refractory lined on the inside?

Edit: sorry that one isn't castable but it's a good choice non the less. Up to 3000 degrees!!
Use the High Temp Tools link O-sin provided; they have everything you need. I used this stuff from Amazon. It is keeping the heat in, but it flakes off really easily (for instance when placing and removing firebricks. When it comes time to recoat it (really soon), I will use actual ITC 100.
Also, one thing I've noticed in my own forge that I never considered is this part of the brick is going to catch a lot of heat and kind of interrupt that good swirl. If you can fill that gap somehow, it'll make a big difference.
These are the cements that I have at hand. They are premixed and rather dense. My plan is essentially to slather it on there until it is well coated. I'm going to further rigidize the wool before doing so, so that it does not collapse down. The blanket is very thick, so I did not need to glue it to the forge body.

I did some more research today and i was planning on using kaowool and ITC 100 or something similar, instead of the sand and plaster. I'm just having a hard time finding where to buy both. I also don't know if ITC 100 is the best option.
Edit: Im looking at this for kaowool, and this for the cement.
How much of this do you think I'd need?

Ceramic wool is specifically made for applications like this, it shouldn't just burn up. It sounds like you've got wool not rated for the right temperatures or something you're putting in the forge is degrading it. Either way, if commercially available products aren't working, then homemade ones are very unlikely to work. I've used stuff like this and it held up great.
