tsugeta7 Posted September 23, 2019 Share Posted September 23, 2019 I'm looking to build my first forge and am having trouble finding a good refractory. All the ones at local stores are either rated 2200F, or don't come in large quantities. PSH has a 50lb tub listen on their website but no heat rating. Does anyone have any recommendations for a refractory that'll go on top of kaowool located in Ontario? Quote Link to comment Share on other sites More sharing options...

Just need to double check math quick for how much i'd actually need. Assuming 90lb per cubic foot, which i believe that kastolite 30 is, my math is as follows: Arch 6" radius - wool = 4" 0.5" of refractory 3.5" tall 301.44 Total Volume 230.79 Inner Volume 70.65 Difference Walls x2 12"L x 4"H 48 Total Floor 12" x 12" x 3" - wool = 12"x12"x1" 144 Total 274.65 cu IN total 350 cuIN 30% safety Which would mean I would need about 20lb of refractory if my math is correct. Attached is a rough drawing of the forge. Black is kaowool, gray is refractory, yellow is my burner Quote Link to comment Share on other sites More sharing options...
pnut Posted September 23, 2019 Share Posted September 23, 2019 I think the ceramic blanket only needs to be two inches thick. Two one inch layers. I don't think more really improves performance. Pnut 3.75 lbs. of Kast o lite 30 will cover one square foot at a depth of 1/2 inch. I didn't check your math but here is one more data point just to make sure your calculations are correct. Good luck. Pnut Quote Link to comment Share on other sites More sharing options...

Read that anything more will act as a heat sink and take awhile to actually heat up. Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted September 24, 2019 Share Posted September 24, 2019 Good Morning, Go to an Ontario Artist Blacksmith Association meeting. Any of their members will tell you where to purchase what you need, locally. If you can't find their web-site, PM me and I will send you the information.

SLAG Posted September 24, 2019 Share Posted September 24, 2019 Mr. Tsugeta, You aver that you are located in "Ontario", Canada. That information is not too informative. The province is enormous. The Distance between Kenora Ontario, (near the Ontario-Manitoba border) and Kingston Ontario. on the Saint Lawrence river is 928 miles. A robust two day drive. The distance between Windsor - Detroit and Hudson Bay Ontario, is 610 miles. (as the crow flies). I suggest that greater specificity of your whereabouts would be of value to members near you. SLAG.

SLAG Posted September 24, 2019 Share Posted September 24, 2019 Great, I lived in Mississauga, ("west" Toronto), for several years. Also, Hamilton, Ottawa, London, K-W, Sudbury long ago. I miss those days. Welcome to I.FI. , SLAG. You can find me in St. Louis these days. Quote Link to comment Share on other sites More sharing options...
tsugeta7 Posted September 25, 2019 Author Share Posted September 25, 2019 I found a place in Smithville (~40 min west of Niagara Falls) that sells Mizzou for $45CAD per 55lb bag. They only sell minimum of 55lb bag, but it's $0.88 per lb. It's the manufacturing plant that sells them so they've just gotta take some information down before you can buy. here's the link for anyone else https://thinkhwi.com/products/mizzou-castable-plus/ Quote Link to comment Share on other sites More sharing options...
