I don't watch vids with AI voices or annoying music, I'm so glad you left in just the simple sounds of the location and activity and just used captions.
The steel industry is probably one of the coolest out there. The raw power and clever thinking and planning required to turn raw material into refined products is astounding.
I always imagine him lying when he says " not sponsored" And the now has a 2 ton steel wire roll in his living room. A pillow on it to make it more cozy.
By the way, Curie Temp is what you were referring to with steel losing it's magnetic properties....anything above Curie Temp has a misalignment of the steel atoms making the steel less-magnetic than below Curie
Yeah. In a sufficiently hot piece of steel, there is a magnetic symmetry - the orientation of magnetic fields doesn't matter, and is essentially random. If you apply a strong external magnetic field, they will align with that external field, breaking the symmetry (=paramagnetism). But even without external fields, as the steel cools down, that symmetry is (spontaneously) broken anyway. Of course, if you keep that strong external magnetic field, that piece of steel is also going to be strongly magnetised, which is usually undesirable! And if you _want_ a magnetised rod, you want a lot more control over the magnetisation than you get from moving the rods with an electromagnet. So I suspect it's not just about steel being less attracted to the magnet; you want to avoid magnetising the steel too. Also, let's not forget that until we get to the point where the billets are (relatively) cool, the whole production line is a stream; the electromagnet is working with batches. So even if you could use an electromagnet to pick those billets up while they're still hot (and you probably could), it wouldn't make much sense. You also probably want to keep some separation between them until they cool down properly to prevent damage, especially since they have different temperatures.
14:04 Missed opportunity to caption this a “robot graffiti artist”! (No really, this channel’s captions are consistently fantastic. Detail and humor, well done!)
AMAZING VIDEO! Enjoyed learning the process of steel making. Modern society is GREAT!! Not so long ago men risked their lives doing every step of this work.
14:24 when it's hot electrons inside the steel are moving like Usain Bolt, and that's why it glows yellow. The magnet work by attracting electrons. But here he cannot grab them
You really get an appreciation for how human technological development is shaped like a ladder when you watch this video and notice how much of the steelmaking process uses steel machines.
@@KirkHermary You're a deepfake ;) Also, I thought the commentary was lacking. It glossed over the most interesting aspects like the chemistry etc. I get it, big things moving doing big things wow wow wow. But that's 5/10 when it could be more. Maybe folk that are only interested in that and bored by any depth would have different opinion, but they're subs, if you just wanna see big shit move you can turn them off. Missed opportunity, sub optimal production.
Brilliant commentary! I'm fascinated by the energy and economic scale of steel processing. This company probably has evolved over time but even at a small scale the capital investment would be several zillion dollars to set up a production line.
35:41 Uses a vacuum to pick up the panels. I see air hoses.🥰 And I always wondered what tool was used to put those fixed nut things in. ( Believe its a swage nuts?) Thank you for the revelation!
Hey there! Long time watcher, new subscriber. The grey powder during the concast process is graphite. I see ways the refining process from iron to carbon steel could be improved, (less heat loss, less energy used) but until I become insanely rich I can't implement my ideas. This is still far more efficient for raw Carbon steel than most processes.
Aahh, plain, simple narratives explaining the process and steps. Very informative and it gives a piece of mind. No annoying AI voice or music or graphics. Well done. I just subscribed. 🎉
14:17 Iron atoms create magnetic domains inside it that aligns magnetically in certain directions, like cells that are uniform. When the material is heated enough the atoms kinetic energy becomes so great that these domains collapse and individual atoms can’t form magnetic domains with enough magnetic uniformity to be magnetically attracted. Adding as some said, you can ”force” them to align with a sufficiently strong magnetic field that overcomes the atoms kinetic energy.
Such an enjoyable video thank you so much for this you worked incredibly hard and I can't believe there's only a half a dozen people I noticed in the whole place! And to think, all the machines in there somebody had to think about it and develop it, and then assemble the assembly line amazing 😍
14:17 Ferromagnetic materials are only magnetic below their Curie-temperature (named after Pierre Curie, husband of famous Marie Curie). Above that temperature, they aren't magnetic at all. For iron, the C.T. is about 770°C. The typical red glow of hot materials begins to be visible above 750°C. It starts with a deep reddish brown, goes to bright red at 850°C to bright orange at about 1000°C. All this is well above the C.T. of iron.
Not _exactly_ - they aren't _ferromagnetic_ above their Curie temperature, but they are paramagnetic. It does make the attraction much weaker, but I'm not sure if that is the reason the electromagnets aren't used for the hot billets (though it was my first thought too). I can think of a lot of different reasons :D
Heating and reheating is very important process in steel industry...its called inknealing... This process takes several steps to ensure the steels strength and hardness is correct for certain projects once the steel is ready to ship...from i beams to ingots.😊😊
It amazes me to think that at one point, there were people who had no idea what this was and even more the fact they learned how to process it. Thinking of how they must have processed it over the years, compared to how it's done today
14:17 - Раскалённый метал, особенно сталь, теряет магнитные свойства при нагреве до определённо точки. Это точка Кюри. При нагреве до неё магнитные свойства еще присутствуют, хотя и начинают ослабевать, но при переходе этой точки, магнитные свойства резко теряются. Это связанно с разрушением магнитных связей с ростом температуры. И упорядоченные магнитные ячейки в кристаллической решётке стали, становятся хаотичными. Такое же свойство наблюдается у магнитов, неодимовых или самарий-кобальтовых; там температуры потери магнитного поля гораздо ниже. Самым стойким магнитом к температуре, насколько я знаю - Самарий-кобальтовые. (хотя может уже придумали получше)
Over past few years that's what I've been thinking, man can build a machine for just about everything, they build machines too make the machine they want, it's crazy and phenomenal at same time.
What were they? Some kind of stud that expands when tightened? To attach to drilled concrete or something? 27:38 Edit: this was the kind of simple stuff that was missing from commentary - seemed half assed. Just a bit of research could've added a lot and resulted in viewers actually learning something. Edit2 LOL ok, they show it like 2 seconds after my comment. I'm gonna leave it just in case it triggers someone. :D
Spot welding is done using high electrical current. The electricity flows through the metal easily, but when it reaches the little area where the metals touch, there is high resistance and melts the parts together. You can think of spot welding like a 4 lane highway full of cars driving 120kph, getting squeezed through a 1 lane bridge, that traffic jam gets hot and melts all the cars on the bridge together, lol
14:21 the magnetic domains of the constituent metal ions are not aligned when the metal is hot because the energy at this stage has significantly excited the electrons to a state of relative disarray. It’s not until the electrons reach a lower excitation that their magnetic domains align in a more uniform direction forming what we know as poles.
0:45 Kinda surprised they're not using self-unloading ore carriers, like they do here on the Great Lakes. Another difference is that iron ore here is ground to a fine powder at the mine, then the iron oxide particles are magnetically separated from the host rock, and then formed into marble-sized pellets
It's an interesting point. I wonder if it's partly to do with the distances that the ships travel, and the offsetting equipment weight against cargo weight, and different manning levels. Or possibly the ports can just have more complex, higher capacity, and better maintained equipment.
When the steel gets wicked hot it wiggles inside, like scared, oiled up baby pigs and the magnet (farmer) can't catch them. That's when his wife, Mrs Curie points at him and laughs
fresh milk for a cow does not need to be processed to be drinkable, it's only when you leave it sitting for an extended period of time throughout the logitical supply chain does it then require some sterilization
the eletrons in steel when its hot are so spread out that magnets have hard time sticking also as temp goes up magnatizum goes down. thats why super magnets get chilled way cold.
Steel foundries to put it bluntly are just crazy, just the sheer scale of literally everything that is going on and the intensity of it all is just bonkers to me...
When I watch these types of videos I often wonder how much does that spool of such and such gauge wire cost, or how much does that roll of sheet metal cost or a box of those bolt and nuts cost. You may want to think about adding the price graphics into the video.
Thank you for not using AI voice. The lack of any voice is calming, and the captions make us pay more attention. Plus your footage is great. Thank you
Exactly what I was thinking 🤝
And it have pure recording sounds too! It felt like you're on site
And without annoying music.
If only the captions were any good, maybe they should have used an ai to write them instead
I wish it was read so I can fall asleep to it😂

Correct...usually well below 3800°C
