Turning Iron Into Hearth Steel - Making Steel! (Forge Diaries: Ep. 16)

Ғылым және технология

We are making high carbon hearth steel in an Aristotle furnace. This principles are simple: combine iron with a charcoal fire and get out high carbon steel perfect for making knives or swords. In practice, this was more difficult. The process here is quite different from smelting iron using a bloomery process in which ore is reduced to iron. We want to make steel by increasing the carbon of the mild steel or iron that is added to the furnace. In practice, this requires an interesting balance between heat and air flow that determines the size of the furnace. The resulting hearth steel needs to be refined by forge welding. It's great to have a power hammer to help with that. Once everything is done, this is great bladesmithing steel and makes beautiful knife and sword blades.

    As a spectator, I find the chemistry that underpins techniques like this fascinating. You'd think that something like anthracite coal would be a better choice for this than hardwood charcoal under the notion that more (higher carbon content and burns hotter) must surely be better, but NOOOOO ... there is apparently a bell curve on carbon absorption involved. Too little heat and you accomplish nothing, too much and you melt the iron and drive off the precious carbon, whereas if you land in the thermal sweet spot the iron can absorb some of it and enter steel territory (then you gotta homogenize it by working it) ... and of course how much carbon is absorbed seems to depend on a variety of factors like the ratio of surface area to volume on the iron, the presence or absence of other elements, where in fire it happens, etc. It's all very interesting.

    i think it was a good idea to start with something over sized, that way you had enough room to gauge the correct size for what you needed(?) thats how it was with my forge, it was too big and i started to line it with bricks to make it narrower until i found the optimal size, then i rebuild it.

    I'm also very curious about this. Actually came down to the comments to see if it was answered yet. My only assumption is that maybe there's different kinds of sparks? He does specify 'exploding sparks' though again I'm just assuming things and have little experience in forging and none in steel production.
