The invention of modern stainless steel can be dated to 1913, and it was done by Harry Brearley in Sheffield, Yorkshire. He was experimenting with steel alloys - combinations of metals - that would be suitable for making gun barrels. A few months later he noticed that while most of his rejected specimens had rusted, one containing 14 per cent chromium had not. The discovery led to the development of stainless steel by a very sharp eyed Brit.
I worked at Titanium Metals in the 70's. We did our melts with electronic furnaces. But wow! This mill is phenomenal. All I could do is wonder how much they spent on the equipment and systems controls. Bet it's more than $50.
Brings back memories... In the 60's, after finishing my schooling at Institut Emile Metz, I spent 3 years at the ARBED-Belval plant in Luxembourg (Arbed is now part of ArcelorMittal). Great experience, learning all the aspects of maintaining the equipment at the plant, before I went to U of Cincinnati to pick up metallurgical engineering.
Everyone should watch this to understand how stainless steel is made, rather than take it all for granted. People use all sorts of things without any thought of how things are made. Being an Engineer I suppose I’m a bit biased, but as a youngster our family had a set of encyclopaedias and I read them all cover to cover many times whilst growing up. Education in all things is important and films like this give an insight of what goes on to make the materials we all use in our daily lives. I run a manufacturing facility, and I had an interesting conversation one day with a worker from another area who was shaking his head and sighing whilst looking at a swarf bin on a machine producing stainless steel parts. He said “look at all that waste!”. I very quickly explained that it wasn’t and he went away with his tail between his legs after being suitably “educated”. Show this to an environmentalist after they have had a life saving operation aided by the use of stainless steel surgical instruments, that will make them think eh?
Great video. I used to drive truck for a scrap metal recycler. Great to see the rest of the processing. Hauled to several ArcelorMittal facilities. LOL, used to use slag ladles to thaw out frozen brakes.
It's nice that a woman's pretty voice can describe the amazing industrial accomplishments that men have produced for the world. Bravo ladies! Keep pumping them out with the kind of loving nurture that only a mother can give.
@@Guitar101Smasher JUST a nice dusting of process lime and grease on everything. "fallout" lol ... quite interesting places to work. stainless spatter on equipment is like razor blades...
I work for the Mill and do the maintenance in one of their Caster’s. It is great to watch the process and see it all happen. When everything goes right! But thing’s can happen fast with steel processes
VERY impressive and thoughly interesting with Clear-concise description all the way through with sutable musicsl bacground that dosen't drown-out the commentary. THIS is how a video should be made. Lije the Stainless-steel, properly done‼️❤️😄 Thanks for a great presentation 👍👍👍
It's a very nice video about the steel making processes. The company though is a different story. Arcrlormittal is a company that didn't treat it's Caribbean workers with respect at all. It's the plant that got mittal his wealth, in the end the workers were treated humanely at all.
Good video I had the opportunity to work for arcelor mital at one of his plants in Anthony Texas in the production of rebar an at the ball mill . A very interesting process From the scrap yard to the melt shop the rolling mill, fabrication and the ball mill. It brought back good met God bless
Wow! that is amazing to see! I sure hope they are doing a lot to use less water and filter heavy metals out before letting that water back into the surrounding streams. That is a lot of water and energy being used right there! I am glad for stainless steel, it is amazing stuff but I am also glad that I do not live downwind or downstream from this plant. I bet those operators are paid pretty handsomely to live and work there though. They are doing important, highly skilled and dangerous work, they should be well paid for it.
Mate, it's in Belgium, pollution got regulated so well there was virtually nothing bad coming out of that plant... which is why it's been closed down almost entirely and production has been moved to Brazil (or replaced by cheap chinese steel) where nobody gives a damn.
Generally speaking the workers and managerial staff at steel mills are very well paid as compared to the other professions and specialities some times amounting three to four times more.
Thank you for the video. A question: I don't see mixing or stirring operation to ensure homogeneity? Or does the O2 & Ar sparging (stated for %C reduction) achieve mixing as well?
Most interesting. I really did enjoy that Having visited a number of steel plants both in Europe and the US I can appreciate the skill of the staff here.
Fascinating process, checking the "mix" of the raw material whilst molten! The commentator's accent intrigued me - Northern England with French overtones?
I was also interested, so I trawled through a library of English regional accents and learnt much in the process. Our narrator is trying to be as clear as possible, and her accent has been heavily modified by education. Nevertheless, even when people are making an effort to speak clearly, they tend to revert to their natural accent when saying short, common words of little import. Things to listen for when assessing an accent include missing "h's" at the start of words, missing "t's" at the end of words, the short "u" being pronounced as in "rook", whether the "a" in words such as "class" are pronounced as "ar" or as in "cat", whether the "r" at the end of words is rolled or pronounced at all, the way "oo" is pronounced, nasalisation of "ing" at the end of words and/or the pronunciation of the final "g", how "i" is pronounced in words such as "hit", pronunciation of the "ay" sound such that "lake" is similar to "like", the rise and fall of the voice during sentences,(lilt), and whether there is a "twang". Our narrator never skips a final "t", always pronounces the "a" in words like "class" as in "cat", never misses "h's", but always pronounces the short "u" in the classic northern English manner, similar to "rook". This combination is common in Lincolnshire, and her strongly northern "u" suggests somewhere north of Boston and probably quite far to the east, inland. Lincoln would be a very reasonable guesstimate, but her accent has been modified by education and the desire to speak clearly!
@@etangdescygnes William - another enquiring mind I see! Living in South Lincolnshire I recognise much of what you say, and agree. I did see some similaritie to a Nottinghamshire accent, suitably "smoothed", as well. In my experience the Boston accent, on teh East side, has a more rural edge with similarities to East Anglia etc. Intriguing that this was the narrator selected by Mittal. I did wonder whether it is someone from Scunthorpe area, where some UK processing plants are situated.
start using adaptive strip oiling or wiping without any energy, no moving parts, no replacement parts or is exceptionally versatile Equipment which can be easily installed in varied machines and process lines
Wow, been 56 years since i seen this process. Better on RU-vid than in person. You know what happens when you drop the roller too much? Kaboom. Downtime, no bonus
Ok, I’m going to admit something I never figured I would. I guess in a normal life span we take for granted things are just built. Never in my wildest imagination would I have dreamed there were factories like this. And it’s been going on since before WW11.
👨💻💭shame the Rollering process isn't close after the steel is made - like it's already HOT so save $ on reheating it - maybe there's a reason 🤷♂️💲 ITS GREAT VIDEO like these types tech stuff factorys more please
It isn't cost effective to make stainless steel from pure materials alone. Usually melt shops use over 85% scrap for a cast and use as little pure material as possible to keep costs down. The end product will be the same
Okay okay, so where did the T1000 unit get destroyed? And what sort of metal would be probably made? Only kidding, video looks brilliant but how do the laboratory testing get the teeny weeny samples from and how?
Mittal will buy your steel mills and restructure them, i.e. cut costs and work force. That is what they do, Vitoria Brasil, East Chicago, IN and others.
We Aussies used to produce most of the SS we consumed but back in mid 80's it was decided to close the operation down at Port Kembla and import it all. BUT before it happened we produced the material that would eventually go into our 1988 new Federal Parliament in Canberra. If you have never seen the huge four posted flagpole that hangs over the sunken building then do yourselg a favour and check it out....200 tonnes of Aussie's best.
Wow, just wow! We are the ultimate form of a Universe becoming aware of itself. It all start inside a fat star that belched all the elements needed to grow humans. Wow, just wow!
Yes. To the narrator she sounds so well , sexy and literate two pluses. Awesome explanation of process. Chatelet, is French for little castle or small house/castle chateau idk?
nowadays the melt shop melts steel (~200tons per batch) @32 minutes in the QBOP furnace (as compared to their ELECTRIC furnace) and the slab caster is faster .see the ATLANTIC STEEL Corp mill at Cartersville Georgia.
@Oliver Mayo yep but guess who is about to be coming back on line. 2020 Fairfield Works putting new furnace on line. We're coming back hopefully like we were. 2nd only to Pittsburgh in steel production.
I have a question: 1. The maximum roll thickness of stainless steel on the market? 6,8,12 milimeters? 2. Why donot they make the thickness harder? like 15 or 20?
Interesting stuff thanks Benoit, hated the music, maybe some jazz, acoustic guitar or drum & Bass or all 3 next time, they'd go well with the talk and the narrator had a nice voice I use and need this metal for my lime putty mortar and plaster work. Without it You can always use wood but it does make thin repairs so much easier. The film was from 2008, I wonder what improvements have happened in the steel mill since, it would be interesting to see how many employee's are left and whether or not it's still even open.
