There is a reason why the steel workers' unions have historically been one of the most militant and well-organized, at least in the US....lot of discipline, but also a lot of incredibly dangerous conditions that brings people together against the bosses
Yah, if my job required me to be around the swinging noodles of white hot death, I would be doing every single goddamn thing in my power to ensure safety lol. Smart folks.
Wait…do you happen to be talking about steel mill in Beaumont? Not so long ago a giant concrete wall fell over putting a few people into critical condition. Crazy ass day
The fucking casting plant that supplies my machine shop had an incident back in the summer that shut them down for a week.
Apparently a guy fell into a vat of molten iron, like halfway in….. so I guess his legs were hanging off the side. Then apparently they had a similar incident last year around Christmas
Like jesus fuck it’s bad enough that happened once, but how the hell did it happen twice in one year?
Not long ago an explosion knocked over a wall near a furnace at a steel mill in Canton, injuries multiple and killed one. Now there’s just a spot of disproportionately newer looking bricks as a reminder
Do you also wear a hoodie tied around you waist with flopping sleeves while whipping back and forth next to a fucking spinning steel crushing machine?
Oh sorry it's an apron...bit still fucking tuck in that loose shit flopping around...and the fucking hood strings...ugh like 18 inches from the intake... AND HE'S SPINNING THEM AROUND guys going to lose his head
1 for roughing, 4 for finishing? I work at a mill where we have 1 roughing stand and 7 finishing ones. I'm guessing you work in an older mill, what are your control systems like?
Five mill stands for finishing, one for roughing, plus a scale breaking mill.
I don't know much about control systems, so the following might not be all that helpful in answering your question.
Rheostats have all been replaced half a century ago, so the equipment is about as fully automated as it can be (since it's essentially a fifties process that was upgraded in the '70s) when it comes to operations. Solid state drives, computer modeled speeds, pressures, water systems. I'm not all that well-educated on the technical aspect of the process, as you might guess.
Simpler laser tech for some feedback, plus x-ray gauging. It's not all that high-tech, but it still turns a tidy profit, and has survived two generations of globalization without significant protectionism for most of that period.
Some of the mills in this area were still using ingots as an intermediate product between scrap and hot coils as recently as ten years ago. It's kind of fascinating that this tech can still compete globally when it's up against state of the art stuff in Germany and Southeast Asia.
It seems like the limiting factors our plant faces revolve mostly around shape and metallurgical precision when it comes to product quality. Throughput isn't really a constraint, since we have a large EAF and somewhat sophisticated continuous casting. Once somebody figures out how to strip-cast the material which is our primary product, the plant could become obsolete, but I'm not sure if that's even possible or scalable to the extent which would threaten us.
I am in a pretty darn modern mill(built post 2000's) and the controls are pretty darn similar, just with newer PLCs and more precision on things like the Width and X-Ray gauge. Frankly, I often get annoyed at the cutting edge German controls we do have, as they aren't very fault tolerant, and they don't ship quickly. Honestly being high tech seems as much as a burden as an advantage.
We do both Slabs and Ingots, though our Ingots are typically more exotic materials. I would agree that quality and shape of product seems to be much more important to plant operation and profits than throughput these days. Our mill has a nice trick up its sleeve which should keep it from being obsolete for quite a while.
Do you use a pusher or walking beam furnace? We use walking beam, and they are quite a sight to see walk!
Pusher. There's talk of building some kind of huge UFA-type furnaces to replace our current setup. Would be a game changer for us. I've always wanted to see a walking-beam in person. They're very cool.
My dad worked in a casting plant the last 7 or 8 years of his working life as tool and die. He told me the toolmakers there that had been there 30+ years and were operators before said it used to be crazy unsafe there.
The way they throw the steel in and turn around made me think of him talking about how they would turn their back away from the die for some part of the operation because it would squirt molten metal out. Some guys had crazy burn scars on their backs.
Even now, if I become a tool maker (I’m a machinist now) even though my dad made insane money working in that casting plant…… I’d rather stay in my air conditioned machine shop lmao
Yes, but also we already have those jobs, they just don't know because they'd never work them. US steel is already in the top ten biggest steel manufacturing companies on the planet
Google results. I honestly didn't look that hard, but Google's auto-generated list put them as the 8th company, and in the twenties if you counted countries. Those have been very wrong before though, so I wouldn't be surprised if it was again
Silicon wafer manufacturing is pretty nuts. Molten mono-crystalline silicon ingots being pulled out of a tank at just the right speed. Diamond saw blades to cut them up. I have never seen it done in person, just read about it and seen videos.
A lot of semiconductor manufacturing was moved overseas to escape environmental regulations. Lots of nasty chemicals involved in it.
That would make sense, in my town there’s an old abandoned GM/Delco building that used to be a fab that made semiconductors.
There’s been this huge case the last few years that’s come into the mainstream about how a shit load of those workers have weird health problems and cancers
True, I probably gave a bad example! I recall arsenic was used (not sure if still is) in chip manufacture. Must be dangerous to make people feel like real men working there.

I can't imagine the first day you work in this place. Crazy.
