Lee Sauder Posted February 8, 2014 Share Posted February 8, 2014 I've been tinkering with another way to make steel in a charcoal hearth-- basically seeing if I can convert iron into steel in the process of forging a knife. There's a detailed version on my website here- http://www.leesauder.com/smelting_research.php look under "Quickie Cementation". I'll just give a brief description here- go look, and then I'd like to hear your reactions and ideas here. ... Here's the hearth setup- I made a bar like this- which gives surface area to carburize at the same time as I'm layering and refining the iron- Stuck it in the carburizing zone below the tuyere- I cycled it up to welding heat several times, and then welded it on the last heat. This whole deal taking 15 to 20 minutes- It was dead low carbon before- now sparking with bursts- I continued to forge it to a blade, heating in the same zone below the tuyere- here's the etch which shows a pretty thorough carburization, with bright lines at the welds- This knife has worked in my kitchen for several weeks, keeps a great edge- I have only tried this with bloom iron, so I don't know how this would work with modern (slag-free) irons, and I haven't pushed it very far either in size or high carbon content. I'd love it if you'd read the pdf, and then play with this, 'cause I bet I won't have time to chase much further down this path anytime soon -share with me what you find!
