Raymond Sauvage Posted March 13, 2012 Share Posted March 13, 2012 Since i´m not alowed to burn coal where i live, i curently use a Diamondback two burner welding forge. I´m very satisfied with the performance of the forge. However after a while there is a buildup of slagg and old flux on the forge floor (dense firebrick), which sticks to everything i put inside the forge. I use some kind of scraper to scrape out most of the flux, but this do not remove everythng. My solution at the moment is to place some flat bar on the forge floor. Does anybody haver other solutions to this problem? Quote Link to comment Share on other sites More sharing options...
MattBower Posted March 13, 2012 Share Posted March 13, 2012 Well, it may be too late now, but some guys like to use a sort of drip pan to catch the flux when they're welding, so the floor stays nice and clean. Quote Link to comment Share on other sites More sharing options...
Old N Rusty Posted March 13, 2012 Share Posted March 13, 2012 i put dry (unused) kitty litter clay on the floor of my whisper daddy gas forge.It has stopped the erosion and glows very hot. Quote Link to comment Share on other sites More sharing options...
macbruce Posted March 13, 2012 Share Posted March 13, 2012 Flux is going to trash the FB period. I've found the biggest headache is not the cost of new brick but tearing the thing apart to put in new bricks. I break up soft firebricks or cut them up in the band saw with an old blade into walnut size chunks then install a dam to keep em in place (most of the time). When they get fouled they're easy to remove or they just wear away. The floor of my forge is trashed but you wouldn't know it, the pix were taken less than a minute after lighting. All the jagged edges capture the heat nicely. Hard FB works too but you can forget about using the bandsaw. Quote Link to comment Share on other sites More sharing options...
Herb Upham Posted March 13, 2012 Share Posted March 13, 2012 A sacrificial sheet of kiln shelving works well ... as does a sheet of stainless steel. I prefer to use SS in my forge. Quote Link to comment Share on other sites More sharing options...
Raymond Sauvage Posted March 14, 2012 Author Share Posted March 14, 2012 The problem is not flux damaging the firebrick. The dense firebrick in the floor of the Diamondback forges stands up to the flux (the dense firebrick is used as a floor on top of the soft firebrick lining). So the problem is to avoid getting old flux stuck on workpiecec when not forgewelding. Igues i wil try to get some kind of sacrificial sheet.

mick maxen Posted March 14, 2012 Share Posted March 14, 2012 I use a gas forge for all my pattern welding work and flux will eat everything it comes into contact with. My solution is to use a piece of stainless steel, as Herb says, on the forge floor to rest the work on so it does not come into contact with the goo. Mick.

I've found that once hard firebrick is coated with the dreaded goo it no longer reflects heat nearly as well....a titanium plate would last a long time.............................................................................
