Refractory temps

How much heat does the refractory lining need to be able to handle?
Verios dealers sell blankets with different heat ratings
Elis sells 2400?F and 2700?F at $8 and $15 pr feet.
Budget sells Durablanket that is ratet max 2300 and operating temp 2150?F
Anvilfire sells Kaowool with a rating of 2400?F
Im going to use ITC100 over the blanket so that will help.
What blanket is recomended?

What will happen if my forge gets above 2300?F with the Durablanket? will it burn or will the ITC prototect it a bit so it kan handle 2300++?

What are you using? Do you have any experience with this stuff.

Im using a T-rex in a forge that is about 4000cm3 35cm long tube with a r=5-8cm
Im going to forgeweld in it.

Any of those products should work fine. The little forge I built has one inch of Inswool lining it (2300 F I think) with a thin layer of Satanite painted on over that and no ITC-100 or similar product. We were forge welding 15 pound billets in it with no trouble so, whatever the temperature was, it was enough. It's the welding flux that breaks down the wool even more than the temperature and ITC-100 doesn't protect agaisnt that. The flux doesn't care what the rating is on the wool, it will eat them all.

Bottom line: buy the best wool you can afford, cover it with refractory like Satanite and use ITC-100 or similar product if you have it to improve the heat efficiency. Use fire brick in the bottom of the forge to try to keep the flux away from the wool and be prepared to patch and replace the wool on occasion ....
