Stainless Steel Production Process - ArcelorMittal Châtelet Site

A movie from Benoît Huc - Tango Vidéo

[@2394Joseph]

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.

[@markharrisllb]

A fascinating video. I knew the rough process but not the details, also seeing it done on such a massive scale was awesome.

[@stephenfuller300]

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.

[@dec5551]

Brilliant! Very concise and informative!😃👍

[@montyzumazoom1337]

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?

[@vanekert]

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.

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.

[@relikvija]

Tom Kelly we know you work at that factory, don't be so obvious... just go ask for a raise

[@PiFe00]

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.

[@akhtarbashir7839]

Hi, Benoit Huc. How can reduce value of austenite ss technically???

[@johngreen8693]

Fascinating process, checking the "mix" of the raw material whilst molten! The commentator's accent intrigued me - Northern England with French overtones?

[@etangdescygnes]

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!

[@johngreen8693]

@@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.

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.

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

There's an energy balance. Compressing with such huge forces add heat enough to keep the process going. On the other hand the water keeps the rolls cool enough to perform their job.

Plastic will burn off. Other elements can be removed to the slag in the AOD by blowing gasses through and turning the unwanted elements into oxides which float to the surface. Also if they're making a 304 grade they will use 304 scrap, they don't just put any old scrap in the mix
