Those shots of the first arc furnace were just amazing.
The engineering behind the assembly line is truly remarkable
Спасибо за подробный показ производства, от и до.
Очень интересно!
INSANE SCOPE of operations...The equipment is HUGE!
Please note that this is a "RE-MELT" operation using steel produced elsewhere. Those facilities make coke from coal, iron in a blast furnace and then the iron into a giant kettle with scrap and an oxygen lance lowered to blast the combination. The kettle is removed and can go into a continuous casting vessel that drops the hot steel from the bottom into a curved, cooling mold section that generates a length of square billets that are cut and later rolled into structural shapes like in this facility.
How do they know the scrap steel mixture they are loading comes out the proper grade steel required? I know they add ingredients to it, but I see a lot of different types of steel being loaded.
@@MillermaticS They have a general idea what type of steel is being loaded. Then after it's melted they take samples and test it. Ingredients are then added to get exactly what they want for a finished product.
@@regould221 Thank you
@@regould221in industry adding of ingredients is in fact alloying. The final product is steel (alloyed iron)
It’s one thing producing the product and another thing building a factory like that! Insane engineering
Creating is an order of magnitude more difficult than using!!!
@@karabas.barabasсоздаётся по проекту. На оснащенном производстве. Сложнее вообще то всегда ремонт. Эксплуатация не сильно сложно. Иногда ремонт нецелесообразен.
The part with the arcing electrode and the furnace is amazing. Almost like a Marvel's movie.
I was thinking The Dark Crystal.
Essa indústria está de parabéns, eu fico de boca aberta de pasmo de tanto que isso tudo é muito incrível ainda mais aproveitando descarte reciclando ❤❤❤❤❤
Корея в основном делает металл из металлолома, потому изделия очень качественные. Чем чище исходный продукт тем качественнее изделие
Свои производства они сохранили не то что у нас.
Они крупные судостоители ещё
Я не понимаю как они выдерживают марку стали, ведь они закидывают в печь буквально всё подряд...
Thank you for filming this documentary and it was very interesting to watch. Nicely displayed.
"What grade of steel are your beams?"
"Yes."
Haha. I kinda came here for this comment but it needs some context so people don't get the wrong impression.
The arc smelting furnace generally has one (or both) of two kinds of instruments that analyse the molten steel on the fly.
The first is an optical emission spectroscope, which analyses the emission spectrum of the hot molten steel and can give an accurate reading of the presence of phosphorus, oxygen, magnesium and so on in the mix. The second is XRFS, or X-ray fluorescence spectroscopy, which works similarly to OES but is induced by bombarding the melt with X-rays and analysing the resulting X-ray flourescence of the excited atoms. This instrument is better than OES at analyzing the concentrations of different elements in the melt.
You can see at one point a shute drops a load of stuff into the crucible - this is them adjusting the mixture as needed . You can see in the second pour that there appear to be stray chunks of solid metal laying about on the floor around the crucible, these are most likely magnesium or chromium or whatever was a required alloying agent du jour.
Even with the scrap, it's 100% a recipe. Each pile is sorted to a degree for the elements, although it might not appear so. Great vid!
Superb, felt like you were there, thousands of tons of scrap steel waiting to go into the charger, would love a visit the mill & have a tour...Music is by '' Diamonds & ice, Grow through changes'', music fitted the video perfectly.
The scale of this factory is amazing.
This is one of the best-produced videos of this kind, thanks
This is honestly some of your best work! The videography is fantastic. The scale and size of the processes is simply amazing.
I had no idea.
VERY VERY impressive!
One of the biggest DC electric arc furnaces I’ve ever seen!!!
감탄사 연발입니다
감사합니다 👍
Having worked at a major steel mill for 35 years, this video was amazing.
観られてよかったです。ありがとうございました。
Great video, industrial engineering on a enormous scale.
Просто потрясающе...Вот что значить-21 век......
There is true beauty and drama in heavy industry, and you captured it well. Bravo!
Это что-то невероятное!
Quá tuyệt vời

Wow beautiful works, Very professional way to finish the product.

This is a scarp melting furnace using an enormous amount of electricity in the form of an electric arc. Blast furnaces can melt raw iron ore as well as recycled metal, while electric arc furnaces only melt recycled or scrap metal.
Blast furnaces primarily use coke to supply the energy needed to heat up the metal.
20분 가는줄 모르고 봣네요 잘봤습니다
Vídeo informativo de excelente qualidade. Parabéns!.
Thank you for showing the process involved in recycling steel into new products
Nhà máy cán thép của Hàn quốc tuyệt vời .
I loved your effort to make this kind of video. Please make more interesting videos like this✌️
The only thing that i interested in is how is big the transformer that can provide that huge ammount of current that melts the metal
В среднем мощности дуговых печей варьируются от 30MW до 120MW. Я был не на этом, но тоже с дуговыми печами производстве. Запитка трансформатора в моем случае была от 220KV линии, а выходные шины трансформатора шли на электрод. Выходные шины были из медных труб, по ним шла вода рециркуляции. Отдельно был блок компенсации, короче power factor correction, эта штука была из небольшого здания конденсаторов. Я говорю о переменном токе. Если печь на постоянном токе, она ещё сложней. Габарит трансформатора примерно как полтора-два вагона, и стоял он на рельсах. Выходной ток на электрод дуги должен быть не менее 50kA, но может превышать 100кА
gracefully. beautiful.gorgeous. mesmerizing. 🤩
촬영한다고 고생하셨습니다
포항동국제강 옆으로 많이 다녀봤지만 생산과정을 적나라하게
보여주는것은 공중파보다 더 낫습니다
Tell me you didn’t get Geonosian droid factory vibes watching this. Great video!
Yeah it looks like it's from a movie, The massive doors opening, The dramatic light shining upwards as some kind of beam slowly lowered into The foundry. It's like watching some kind of arcane ritual. I can totally imagine this being the section of a movie where they show how they finally complete the ultimate superweapon that will destroy the Galaxy, that the heroes will have to destroy, or something.
Impressive process, great video.
Genuine heavy industry!
Основная фишка этого фильма ради которого всё снималось состоит в том что :
А ГДЕ ЛЮДИ ???
Very nice video
An impressive amount of scrap iron!
I thank my great brothers, photographers, for their great effort in producing this amazing content.
My greetings and appreciation.

와.. 이번건 진짜 지린다 4분대부턴 무슨 sf 시작부분 보는 것같네 ㅋㅋㅋ
Great contry,love❤❤❤from nederland.
쇳물에서 바로 H-빔이 만들어 지나요?
보통 블룸을 만들고 다시 가열해서 압연공정을 거쳐서
만드는걸로 아는데요.
편집과정에서 안보인건가요.
전기로에서 보통은 빌렛 블룸 단강을 1차적으로 만들고
빌렛은 철근,환봉 블룸은 H빔 단강은 단조제품을 만들죠.
다만 동국제강은 단강은 생산하지 않아요.
보이는것 보다 3배 큰 공장인데 후판 1,2 공장은 폐쇄 됐어요.
안타깝죠.
정말 놀랍습니다
촬영하느라 고생하셧어요❤❤❤❤❤❤❤❤

Video muito legal 2:24 show
A small correction, the beams at the were actually H beams. When they started they were still I beams.
Correct, however most ppl would not know the difference. Thank you for making this comment. It is a remarkable video of a truly heavy industry.
눈물이 나올 지경입니다
철가루 들어갔어요?.?
En mis años de estudiante visité una fabrica en Barranquilla que producía cabillas lisas y corrugadas de varios diámetros, al igual que perfiles angulares, me sirvió enormemente en mi desarrollo profesional. Saludos desde Venezuela.
Good work
LIKE Y SUSCRIPCIÓN,MUY BUENO EL VIDEO, EXELENTE, FELICITACIONES, SALUDOS DESDE CORDOBA CAPITAL, ARGENTINA 🇦🇷🥇🏆❤️
와 저기 분진 장난아닌데 대단하시네요 ㅠㅠ
great video.
Amazing Dude!!
В состав металла добавить компаунты высоколигированной стали
ты не чего не перепутал- лигатура -- для высоколигированной стали.

Reminds me of Wizard of Oz with all the flames when the metal is added!
5:46 That's the terminator that travels to our time!
bro risk his safety for our watch. Thank you so much.
I would really like to work there
travail de forcat....respect aux ouvriers , qui meritent des salaires XXL....!
Amazing video. Humans are so ingenius!
However, i wish this was used to make Cumberland sausage 😂
C’est de la fiction toute cette technologie
It would be good if you'd decide you want to show how I beams or H beams are made. The two are completely different!
Make an upper case letter I in the conventional way. Two flats and a stick in between. The only difference between an I beam and a H beam is flipping it 90°.
Rusty scrap metal and iron ore are melted down with huge amounts of energy and resources to make steel and the very second it gets made into whatever it is going to be ,
It starts RUSTING again !
Man still hasn't figured it out yet ?
But the energy and resources are gone forever and the steel is turning back into iron ore !
Magnifique reportage sacrée entreprise malgré qu’elle soit omnivore en énergie pour réaliser les poutres H
Interesting show about a subject I am interested in. BUT a narrator explaining the different phases would have improved it 10 fold. Thanks.
Ну самое же интересное это какая же сталь в итоге получилась. =)
Fascinating 👍🏻🇬🇧
정말 재미있는 영상입니다
That arc furnace is pretty scary to watch.
Говорят что высоковольтный электрод плавит металл. Нет, это не так. Для дуговой печи напряжение от 90 до 230 Вольт, сила тока 80-160кА. Это по сути обычная розетка, с током в 100 килоампер.
This is not Pakistan! (this is how professional still mills operate... not the tiny crucibles, with loose clothing and safety flipflops as other videos show.
This video is very hypnotizing 🧐
Impresionante! 👏
Need a video on just how the arc furnaces work would love to see that
Think of a sustained 150 million watt short circuit and you're in the ballpark. Arc regulation is practically a science unto itself.
great video, keep it coming
Amazing 💪💪💪💪
That was cool and interesting to watch🙀🙀🙀
Thanks
아름답네요
* Đoạn từ đầu đến khoảng 06:00 là nấu chảy sắt vụn bằng lò điện ? Tưởng sắt vụn chỉ được luyện lại trong lò Mác-tanh thôi chứ , nấu trong lò điện , làm sao đủ thời gian để điều chỉnh thành phần ? ( thậm chí trong lò còn chưa đồng đều về thành phần ? )
* Đoạn sau : đúc phôi bằng phương pháp đúc kéo ( đúc liên tục ) ?
* Đoạn cuối được nhìn thấy sản phẩm đã cán , trước đó không được xem quá trình cán thép ? ( xem lại thấy : quá trình cán thép chỉ được quay từ xa thôi 😁)
No. The melting is not done using high voltage, but using high current at low voltage.
I can imagine the thickness of the copper wires that carry so much current.😮
Dont be so obsessed about correcting the video creator. The terms "high" and " low" are relative to some other external value; for example it's a high voltage compared to what the average viewer has in their house. But it's a low value compared to the voltage used for transmission lines across country. You know that, and so do all the viewers too. We all did "arc furnace 101" in High School.
@@BrassLock You should work on your comprehension skills. My gripe was over the conflation of voltage and amperage.
@@BrassLock They aren't obsessing over anything. The information provided in the video is flat out wrong. It's not like mistaking HOW much amperage is needed to melt the steel. They incorrectly explained the method of melting steel via electric current.
I like turtles.
I hope the employees over there have some Polysporin by the bucket!
Creating is an order of magnitude more difficult than using!!!
Great video, once I saw the number 13 ……. Definitely not in the US .
Nice
대단하네요
저기에서 나오는 열에너지를 재활용할수 있는 방법이 있다면 조금더 에너지를 효율적으로 사용할수 있지 않을까 싶습니다.
어디까지나.. 저의 생각입니다.
비현실적인 용광로의 거대함에 압도 되었습니다
보통은 전기로 라고 부릅니다.
철광석 고로를 보통은 용광로라고하죠.
I can always tell when a factory is making steel. You see pylons carrying electricity going into it.
The scrap seems to be quite a mixture - how do they ensure the quality of the steel produced?
