KYBOY Posted August 31, 2008 Share Posted August 31, 2008 Well I just bought my first gas forge..A diamondback two burner blacksmith forge..It has a 3200* bottom brick and I was wondering how do you prolong the life while forge welding? Plates in the bottom? Any certain flux that is kinder on the brick? Thanks Quote Link to comment Share on other sites More sharing options...
JPH Posted August 31, 2008 Share Posted August 31, 2008 Hello: I suggest you use a sacrificial plate made from a piece of kiln shelf over a layer of at least 1/2" deep el cheapo kitty litter...that's the easiest thing to do. I do more welding in a week than most folks do all year and this works.. Flux will eat its way right on through most refractory materials at an alarming rate...this will prolong the life of your lining.... Hope this helps...

Frosty Posted August 31, 2008 Share Posted August 31, 2008 A lot of knife makers use a SS tray to protect the forge floor. ITC-100 will provide a little protection. If it's a standard size a fire brick or two isn't so expensive to replace though, nothing compared to kiln shelving. At least in my neighborhood, yours may be just the opposite. My little forge is rammed up with high phosphate refractory and after nearly 15 years shows no signs of flux erosion but it's darned hard to find anymore.

KYBOY Posted September 1, 2008 Author Share Posted September 1, 2008 This one has 3200* ceramic bricks in the floor..Im afraid they may be a bit expensive to replace..Should really last if i take care of them right though.. Quote Link to comment Share on other sites More sharing options...
jimbob Posted September 1, 2008 Share Posted September 1, 2008 I just bought a liner for my whisper Momma. $14.00; from NC Tools..I bet they have one that will fit your forge Quote Link to comment Share on other sites More sharing options...
bipolarandy Posted September 1, 2008 Share Posted September 1, 2008 I got a bag of "bubble alumina' anti flux refractory coating for my old forge that I welded in alot, and it worked wonders. From what I saw the stuff is completly imperveous to borax and borax acid. Refractory Coatings - Ellis Custom Knifeworks Quote Link to comment Share on other sites More sharing options...
Jymm Hoffman Posted September 2, 2008 Share Posted September 2, 2008 I use Plastech 85 in the bottom of my forges from: ANH Refractories I can't remember what I paid, about $75.00 or so for a 55 pound cube. I use about 1/4 to 1/3 of this to line the bottom of my 2 burner forge. The stuff lasts nearly for ever. The flux can build up and puddle like glass and it will not damage this stuff.

Frosty Posted September 2, 2008 Share Posted September 2, 2008 Good supplier Jymm! The stuff you're using is a phosphate bonded refractory which makes it pretty caustic resistant and flux proof. Good choice. High phosphate or even phosphate bonded refractory is hard for me to get since Pyramid went out of business. Thanks for the link.
