From Wrought Iron to Steel - Making Hearth Steel
HTML-код
- Опубликовано: 25 апр 2021
- Ever since I fell in love with swords, knighthood and blacksmithing I've always wanted to make my own steel. Now that dream finally came true and I am happy beyond words.
Hearth furnace was used throughout the history to refine iron and turn it into steel. In a controlled atmosphere iron melts and imbues with carbon from the charcoal.
I dedicate this video to Emiliano Carrilo whose unselfish advice and help made this project possible.
I also give my thanks to Goran, my dear human power-hammer. This would not be possible without you as well.
Timeline:
01:05 - selecting wrought iron
01:50 - checking for fibers to be 100% sure its wrought and now mild steel
02:09 - wrought iron was cut into small peaces, 6x150 grams
02:20 - making ash bed
03:50 - slowly adding iron and charcoal
05:18 - consolidating the puck and celebrating
07:20 - spark test
08:03 - consolidating the puck
10:07 - folding the peace to consolidate and purify the material; this is done at least 8 times
In some future video this steel shall become a knife, so stay tuned!

Cool stuff! Your furnace is the smallest, simplest I’ve seen. I’m in Northern Alberta. Intend todo a bloom this summer. Thanks guys, great work.
Thank you so much for your kind words. Emiliano Carrilo helped me a lot with this project, so make sure you watch his video as well before you start making. Good luck with the project!!
@@poemaincudisworkshop4366 , I will for sure! Thanks
Love it!❤👍
Thank you so much!!
Such precise work! You do have some patience to create these pieces. 👌🏼👌🏼👌🏼
pogledao na redditu, dosao ostaviti like. odlicno momci, svaka cast :)
Hvala puno na podršci!! :D
Nice job 🔥
Well done
Thank you very much!
Bravo Majstori! Čekamo nastavak...
Bude bude :D
Odlično🖖🏼
Wow nice! My friend Bralson showed me your channel. New sub! ;)
Thank you very much for the support!
Legendo!
Prekrasno! I svaka čast! Baš mi je drago da ti je uspjelo. Ako si u blizini ZG, rado svratim koji put da pomognem s lupanjem :)
Hvala viteže! U blizini Splita sam, pa kada budeš išao na more moja radiona ti je otvorena ;)
Bravo brate!
@Poema Incudis asu, kralju, zmaju, školjko 😁💕
amazing there is going to be continuation to this one i hope
Don't worry, there will be ;)
Did you ever try hardening any of this material?
Yes I did and it gets a very good hardness. There will be a future video where I forge a blade out of the steel from this video; so stay tuned ;)
Wonderful work, my man. Video quality/sound quality/editing are all really great. Your workshop looks like such a cozy place. I don't know anything about forging or metalwork; what is the powder that you put on the ingot around 10:25?
Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel
Thank you very much! Glad you like it :D
Goran said it all. It also stops the oxidation of steel and keeps the steel clean.
@@poemaincudisworkshop4366 Ah ha thanks lads. Looking forward to seeing more work in your shop Ivan!
how long did the smelting process take from when you added the first pieces of wrought iron and how much charcoal did you use?
First of all I apologize for my late response. And about the process, well, it was surprisingly short; about 1h I would say, maybe even less. Also about the charcoal, I think I used around 5-7 kg.
@@poemaincudisworkshop4366 Thanks!
💪🔝
Famozno!!!
Hvala puno!
@8:58 doesn't heating the steel enough to throw sparks like that cause decarburization?
It does, but the bloom has so much carbon that it is desirable to loose it a bit (it is around 2-3%), and get it to around 1% which is lets say ideal for further work. I have tested the peace afterwards on the grinder and it still sparks those explosive sparks like crazy which means that it's still high carbon.
Suitable for fire steel sparklers???
This is great! I have a few questions if you can help please. Is that just charcoal or coke/coal? Is the bloom/ingot high carbon steel? If so is it full penetration or just surface hardening? Thanks.
Hey Brann! The charcoal I use in smelting process is a regular old hardwood charcoal. Later i forge the bloom in a mixture of coke and hardwood charcoal (50:50 ratio).
By the spark test at 07:24 you can notice that the sparks are indicating a high carbon steel, and I can say that I was very surprised that the carbon got all the way through the material. Forging and folding was mainly done to get the impurities out. If some peaces were lower carbon then the folding would be for that purpose also (which usually is).
Hope that helps!
@@poemaincudisworkshop4366 could i use like small sheets or strips of wrought iorn instead
@@driplord6150 Instead of what exactly?
@@poemaincudisworkshop4366 could i use wrought iron scraps , to smelt instead
@@driplord6150 well here I was using wrought iron bits and peaces, mostly uniformed size. So yes, you can use it!
I think you missed the vital parts of this video. You put coal / charcoal in but skipped the part where you put the iron in.. Why is that?
I think you can see that at 03:50
Peaces from the papers one by one.
@spaaggetii I agree that it could have been more visible and plain; but you can see it at 03:50 ;)
