Steel making is amazing, I worked in a steel mill many years before I left due to health issues ! The shear power & weight of this equipment is unreal ! Miss those guys, loved that job !
Furnace arc transformers are directly connected to the furnace without a breaker in between they are usually: they are installed on the same height or even higher than the furnace not on the ground level. Delta primary and open delta on the secondary. Most of older transformers are shell type core. Secondary voltage are very low to 200 v it depends from one design to another and current can be up to 85 KA on the other side the primary is normal medium voltage rating of the country. Higher rating transformers will have built-in reactor to react as load when the furnace is off after completing melting or during refilling of the furnace. Also higher rating transformers will have three diverter switches on each phase of the transformer and another three diverter switches on the three phases of the shunt reactor. So total diverter switches on one transformer are 6. These transformer are usually in closed air-conditioning rooms and having water heat exchanger as cooling method doesn't have radiators or fans. This is general info about them
Let's say one solar panel produces 500W at peak performance. That's about what a normal panel produces. About 2x1m, 2m² Let's take a 5MW furnace for the sake of simplicity That's 5 000 000W. We would need about 10 000 solar panels for a small furnace. That's 20 000m², or 2 football fields covered in 100% efficient solar panels, without any power loss and 100 uptime Now take those numbers, and do x20 for a normal sized furnace
Should have seen it earlier. Looked 10 times crazy. Hot steel would fly out the front as the eaf rocked back and forth. The ground shook, your bones vibrated.
Why didn’t this show up in history books? Carnegies process sure did yet he was a stock market cheater, inside trader, a fake from the start. This is really better
Lets just say double that when it was first started. Melted steel would fly out the front when it dipped off the slag. It was like watching 10 top fuel drag cars launching at the same time.

It fascinates me
Awesome. These things look like something out of a science fiction movie.
Yes, to control this process is an art and this equipmant is old design by SMS CONCAST
Damn! You can even hear the electric current happening in there...WOW! Sounds super hot 🔥.
The loudest sound you could imagine. With double hearing protection it was still crazy.
probably enough electric to power a small city
@@mcrawfmeister1:26 sound buzzsaw RR Conway 508 fanblade on old 707 takeoff👍👂
Not so many pops, just the sound of pure electricity. Nice
All scrap is melted to a bath. Melting down the scrap is deafening.
This sounds like a huge power plant substitution
Noice
Hi thanks for the great 👍 video for me you can’t beat it’s site and sounds of the melting shop
1:22 Sound old fan engines RR conway C508 on 707's takeoff...
Good music on my hears!
The thing coming out of the ground on the right side and bending into the furnace looks like it came from the movie, “Alien”.
Sounds better at 50Hz :)
Reminds me of the Carbon arc lamps once used in the graphic arts industry.
Oh so thats what i was hearing! That hummmmm its from this exact steel mill i live by it
may I ask what location is this at ?
Yes Sir furnace operater has a melt going O Ya the sound of Money
I LOVE THIS!!!!!!!! POWER POWER POWER!!!!!!!!
at 45k amps special transformers near the plant to boost the amperage

Hey these guy got a door in there slag off hole lol, we never had on that fancy
I remember them days Griffin Wheel Kansas City Kansas
I imagine the doorway to Hell would be like this 🙄
How many wind mill or solar panels does it take to power 0ne furnace 😅

Why not use coal or natural gas?
You should put a Go-pro inside there so we can see what's going on!?🤭
I think that's a good method for VigStackt to melt his model. He can upgrade his Devilforge from gas to electric.😅
Usefull video very nice thanks
How many time to liquify the metal inside ?
How many times what? Do you mean how long you need to heat it? It depends on how much scrap is in there
Wow sounds cool but kinda like its gonna blow up
Should have seen it earlier. Looked 10 times crazy. Hot steel would fly out the front as the eaf rocked back and forth. The ground shook, your bones vibrated.
Why didn’t this show up in history books? Carnegies process sure did yet he was a stock market cheater, inside trader, a fake from the start. This is really better
I think it's slightly hot
Yeah definitely a bit hot
I am ceran opretar
nice video
how many amps???
Good question.
45,000 to 90,000 amperes
the trend is a DC EAF...
Please make more 😁😀
The mill has been idled for years now.
Wow
Hey, we make graphite electrodes.
Send me some
love me some graphite electrodes
this is a furnace on steroids!
Lets just say double that when it was first started. Melted steel would fly out the front when it dipped off the slag. It was like watching 10 top fuel drag cars launching at the same time.
how many amps
Thousands.
Atleast 80000 amps 110 MW
