I am asembling stuff to build my first forge. I have about 6ft of 2in thick kaowool. Do I need to coat it with anything if I am just using it to heat the steel? No damascus (YET). Isnt the coating just to protect against the flux used to make damascus. ANY HELP WILL GET PUT TO GOOD USE. Thanks.
 
A coat of castable refractory will generally decrease the time and fuel cost to heat up the forge.
 
You at least need to coat it with Satanite. It is rated for a much higher temperature than the Kaowool and will keep the liner from burning out nearly as fast and makes it more rigid so it stays in place. Also makes it more efficient. To be really efficient you'll want to put ITC100 on, which is a coating that reflects heat.
 
I come from a very over egulated country. However I was speaking to a kiln maker when buying supplies. He told me it is now government regulations to coat even kilns for all government schools and applications. Concerns over the fibres being brieathed in and causing future lung desease. It may just be a precaution but I would coat it anyway.
 
You should not run it without a coating on the wool. I was told that the Inswool uncoated in dangerous for the lungs. Something like asbestos but not as bad. :eek:

Bleh! I would coat it if you are going to use it. That stuff is nasty to breath, and I woudl not down it from asbestos at all. it does the same ugly stuff to your insides.

I will find the address I have for an outfit that has 5K degree castable refractory. That stuff is like concrete, and won't decompose under the flux or heat.

Doc, post that address on here if you don't care. I would like to have a little of that myself, if flux won't affect it.

Thanks,

Bill

Please post it,we could all use a super HTemp castable.

yeah what he said :D
 
IMO 5K castable is over kill.
The castable works by soaking up heat and then releasing it to heat the work.

I had a little forge lined with a kwool lineing and decided I didn't like tearing up the wool and hacking it up (kwool I mean) ever time I used the forge.
I replaced the kwool with 3k castable it would not reach welding heat.

Nothing else was changed about the forge. It now also took 10-15 minutes to reach forgeing temp.

In my new forge I use a ceramic fiber lineing with a ceramic fiber RIGIDIZER.

I really like the rigidizer, I have the same fast heat properties of the kwool, but it now has a tough outer skin that doesn't flake off like coating it with some other refractory.

Now,,yeah you can damage it with the rigidizer on the kwool, but just brushing it with a hot blade won't damage the wool like the uncoated stuff.

AND it stops those pesky fibers from getting in your throat.

email me if you want some
 
I dunno I tried some ITC100 on the kwool I wasn't that impressed.

Some folks really like it. It's just not worth the money to me. It flakes bad too.
 
Just got back in from holidays. I forgot to get the addy, but will post it tonight when I get home.

I would do the ITC100 over any castable refractory and would consider using it over satinite.
