Callebs Creek Cutlery Posted March 17, 2020 Share Posted March 17, 2020 (edited) I'm wondering what I need to coat the inside of my forge with if anything. Its built out of 2300 IFB. I'm also not sure how to add a flare end to the burner bodies as it goes down into the top. How far into the bricks should I position the bodies? I'm using 3/4" x 10" black pipe. Any other suggestions are welcome. Thanks Edited March 18, 2020 by Mod30 Resize large photos. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted March 18, 2020 Share Posted March 18, 2020 Anything you coat it with--even kiln wash-- would help reduce the damage that direct exposure to flames will do to that brick; it is meant mainly to be a secondary insulation. This kind of brick became popular as the easy way to construct electric kilns, long ago--not gas forges. If you're not willing to completely rebuild that forge, the practical move, at this point, would be to add a 1/2" thick layer of Kast-O-lite 30 on every wall, the ceiling, and floor of that forge. BUT, do it in stages; first the floor, then the ceiling, and finally each wall. After casting--and curing-- each surface, run tape over the areas that will abut other refractory surfaces. Why; to reduce the chances of them cracking during thermal cycling. I don't see any burners in those photos. I only see a plumbing system for two burners.

Irondragon Forge ClayWorks Posted March 18, 2020 Share Posted March 18, 2020 I don't see any way to connect the plumbing with the mig tip orifice's to a burner body either. Quote Link to comment Share on other sites More sharing options...
Frosty Posted March 18, 2020 Share Posted March 18, 2020 Welcome aboard CCMW, glad to have you. If you'll put your general location in the header you might be surprised how many members live within visiting distance. Who's forge and burner plans are you following? Have you asked the author? What you have now some parts for a couple burners. Do you want naturally aspirated or gun (blown) burners? You didn't REALLY weld the forge frame together did you? I sure hope you left a way to change IFBs or it's going to become a dust collector when the too low rated IFBs break up. Even with a good layer of Kastolite 30 and a kiln wash they are going to experience temps above their working maximum and those do NOT withstand rapid thermal cycling like you get in propane forges. There are a number of proven gas forge and burner designs posted under the appropriate sections on Iforge and there are a number of threads discussing the hows and whys for how guys use them. It's well worth a read. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Callebs Creek Cutlery Posted March 18, 2020 Author Share Posted March 18, 2020 Thanks for the welcome and thanks for the advice! I've been piecing together what info I can find on this. My plan was to use naturally aspirated burners with 11/4" to 3/4" bell to a 10" -3/4" black pipe as the burner body. Attached with set screws to the brass fittings above the mig tips. I feel like I should start over. Any suggestion on a link to a step by step tutorial build. I'll include my location SE Michigan, thanks for the that tip.

Frosty Posted March 18, 2020 Share Posted March 18, 2020 If you go to the Iforge opening page and start scrolling down you'll find all kinds of fascinating things but it'll test your skimming skills, there are thousands of posts in this general section. select it and you'll find two of the most recent: "Forges 101" and "Burners 101". Early in Burners 101, I list the basic ratios to make a successful burner, regardless of size the ratios stand. https://www.iforgeiron.com/forum/65-gas-forges/ Frosty The Lucky.

Callebs Creek Cutlery Posted May 8, 2020 Author Share Posted May 8, 2020 I'm looking for recommendations on a castable refractory to line this forge. I found a source that offers satanite high aluminum mortar. Does anyone have any suggestions? Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted May 8, 2020 Share Posted May 8, 2020 We used Satanite topped with bubble alumina and it works very well. Kast-O-Lite 30 is basically the same in one single coat, sold by IFI. https://www.iforgeiron.com/forum/254-gas-forge-refractories-and-supplies/ Quote Link to comment Share on other sites More sharing options...
