Refractory covered Kawool

Hi.
I have been searching the forums to this question but couldnt find the answer I wanted so thought I would post it.

I have a NC knifemaking gas forge which has (I think) Kawool and a fire brick floor.
I want to start pattern welding and am aware that the flux will eat the kawool....soooo, I want to replace the Kawool with a refractory.
Can I just layer the castaway on top the Kawool?....if so, how thick of a refracory do you think I need to add?

Someone mentioned clay cat litter. I am unsure of what to do with this....Do I wet it and make a clay and use it the same as a refractory or do I just scatter it on the floor to catch the flux?

Any information appreciated.
Thanks.
Kevin.

Check this link

http://www.dfoggknives.com/forge.htm

The third paragraph under "Construction" has some details on applying a lining.

The kitty litter thing you spoke of is one way of making a good lining at home. This is what I used to line my forge and it works well. The mixture is 50/50 kitty litter/sand with some wood ash added as a binder a cup or two is all that?s required. Soak the kitty litter until it returns to its soft clay like form then add the sand and wood ash mix well and that?s it. However I found that the kitty litter didn?t want to turn back into clay so I help it along by using an old food processor to pulverize it. I did it after it had been wet for a few days, but after having done that I would recommend that you do it before you wet the litter (it was a hell of a mess).

Hi John.

Do you know where Grand Island is?......( Lake Yale).

I am a (new) member of the FABA and a few of us (20 or so!!!!)are getting together to make some treadle hammers in January...in Alabama.... (I consider myself extremely lucky to have met up with such a great crowd of people).

Once I get the treadle hammer set up then I aim to experiment with pattern welding hence my original question....

If and when I get it set up, your more than welcome to visit me and show me how its done .

Cheers.
Kevin.

If your forge is a NC Tool Co. forge, they make a plate to fit in the bottom of the forge which is resistant to flux and will protect the forge bottom. The rest of the forge liner you shouldn't have to worry about. Give them a call. They are great folks to work with.

Somthing I have just started doing is to line the bottom of my forge with crushed soft fire brick, and dry cat litter mixed togather, this dosn't make a barrier so much as a media to absorb the flux before it gets to your liner, every couple of weeks or so, just rake it out and reline it, its cheap, and easy! I havn't tried plain cat litter, but dont see why it wouldnt work.

Mike
