Resmelting bloomery iron gromps and making steel.

In this video, I show the carburized process of the bloomery iron gromps in a small furnace. Iron gromps are small outer parts of the iron bloom highly contaminated by the slag. I used 2.5 kg of iron gromps and 10 kg of charcoal and got 0.8 kg of high carbon steel. The high carbon material I got I will use in my next project.
Tips:
The diameter of the furnace is about 15 cm. To built it I used bricks and clay mixed with sand. In this experiment, I used bloomery iron gromps but ordinary soft iron also can be used (nails, scraps etc.) The temperature during the process should be enough to smelt iron. It is good to add at the first charge some pieces of slag, slag protect the bloom against burning (oxidation). For making steel do not use phosphorus iron. I use about 400 grams of charcoal for every 100 grams of the charge. The iron pieces should be small.

The sound of hammering going from sounding like hitting wet clay to the tink tink tink if hammering steel when you homogenized the bloom was quite satisfying. Alchemy in action mwahaha lol

Man, that was a good bloom!

Very cool man.

Interesting stuff 🤔

Czołem. W jakim celu były zrobione dwa otwory, skoro dmuch szedł tylko w jeden?

[@officinaferraria]

ten dolny był używany do wysuszenia i wygrzania pieca a zwłaszcza jego dolnej części.

[@oliviermalige3279]

Very informative video !
There is a lot of craftmanship and knowledge in this process, very good results also :))
Is it a simple forge blower or something else ?
Cheers and thanks for sharing !!

[@officinaferraria]

Yes, it is simple electric blower.

Wow you are a bad ass great job . best video ive seen so far! sub'd.

[@onemangamer587]

Hello! I know this video is a year old now, but I was wondering if you, or anyone here could help me understand this:
From bloomery, how exactly are you making the steel?
Is it just by heating it up to a very hight heat (say 1,500°c) and beating it until most impurities are removed and the carbon level is lower than 2%?
I am talking in a more primitive / traditional way as shown in the video, because I've seen how they do it with modern tools and such but I would like to try using only what my land has available.
Thank you in advance for any help!
Also, great video, I really enjoy your videos.

Hi, here you are paper about it: www.academia.edu/12967502/Making_Steel_in_the_Aristotle_Furnace_

[@MrWTPunk]

Good video, thanks.Can you please list the "what to do", "what not to do" to be SURE to get high carbon steel?

[@officinaferraria]

Sure. I will add the list in the video description tomorrow.

[@MrWTPunk]

@@officinaferraria That's kind and useful, thanks

[@MrWTPunk]

@@officinaferraria Update seen, it is precise thank you

Very cool! What is the difference between this furnace and one used to smelt iron from ore - the height? Thanks.

[@majogl188]

afaik, regular bloomery furnace has the blow hole towards the bottom, meaning there is oxygen where molten iron gathers, and the carbon will burn away... In aristotle furnace (for steel making) the blow hole is higher up, creating a space at the bottom where there is high temperature and almost no oxygen, meaning the carbon doesn't burn away and can bind with the iron. And you get steel.

[@officinaferraria]

The construction of the furnaces is almost the same. The difference is in high and diameter. In the small one - Aristotle furnace, the temperature during the process is about 200 C. higher than in the bloomery furnace. The charge (soft iron) is partly or completely smelt when goes down and this causes the carburization of the material (molten iron carburized much easier).

Is folding a detail some iron smelting videos leave out? Also how many folds was that?

[@officinaferraria]

This steel bloom i folded only once,

I love yours vidéo is fuc.... assome 🤟 from where you are???

Hello sir I have make a bloomery when I smelt iron ore lime in bloomery that makes a qlinker not iron it's why please sir guide me please 🙏🙏🙏

[@officinaferraria]

probably the iron oxide content in the ore was to low. Did you roasted your ore before smelting? What kind of ore did you use?

[@uanwar111]

@@officinaferraria please sir give me Whatsapp I will show you my setup and meterial

Can i come live, work and learn with you, please? :D
