I am an EAF operator so I spend alot of time with a machine like this. When I started on the furnace floor nothing could prepare me for the sheer power, noise and heat coming off these machines, when melting down buckets the noise is so intense it shakes your entire body. Usualy we run on a Tenova Consteel conveyor feeding system which is muuuch quieter than buckets and makes better quality steel. 110 ton furnace tapping roughly 75 ton heats every 40-45 mins, uses 25-30 MWh of energy per heat, it's an insane amount of power. I surely would not want to see their power bill loll
I spent a fair bit of time in steel works in my younger days as a maintenance fab/ welder, I remember vividly feeling the mind blowing power of these puppy's ♥️
Let's see....at a rate of 10 cents/kWh, 30MWh works out to $3000. Sounds like a lot, but probably not so much compared to the value of the 75 tons of steel they produce. And maybe they pay less than 10 cents/kWh if they have a special deal with the electric company, because they are such high-volume customers.
@@poly_hexamethyl They pay less but not much less since in the US, industrial producers paid around $0.0666 per KWh in 2020 but other things like shipping their product is very expensive so their margins are actually not that big at all. So it actually doesn't really have anything to do with the cost of the electricity.
Notice the wire cables (inside those tubes) dancing a bit, despite being bundled (most likely copper) and very heavy. This is caused by the large magnetic fields that surround each cable. Fluctuating currents throughout the arc and the melt create pushing/pulling forces against one another.
I saw an arc furnace at the age of around 13 y.o. Our class visited a steel- and rolling factory in Hennigsdorf near Berlin. I don't remember if that pot had a lid at all or if the orifice was just much larger. I was HORRIFIED at that age from the big arcs, the loud boom and bang noises and the sparks and steel drops flying out of it - pure horror back then! 😵💫 I guess now beeing 53 y.o. it would be rather interesting and fascinating. 😉

I worked around EAFs for 30+ years. They were just as scary the last day as they were the first. There's never anyway to explain what you do for a living, they have to witness it and so very few people get to.
Fantastic! Being an engineer myself, nobody would want this in their town, but they are happy to buy things made from metal to use in their everyday lives. All schoolchildren should see this and understand.
I've done work as an outside contractor in a local foundry, the amount of energy required is astonishing. To be a couple hundred feet away when they put a locomotive truck on the shaker and see orange, and also contemplate hiding behind a structural column to shield yourself from the heat is mind bolgelling. Then you realize there are guys standing on top of the boxes while being poured.
This has to use an unimaginable amount of power, and I can't wrap my head around how it's drawn without breaking something. With the arc being inconsistent by nature there will be wildly fluctuating power draws; they must have some very large power handling equipment in factories like these.
This is child's play next to the mayhem that was Homestead Works' Open Hearth #5 melt shop. Eleven furnaces, each one able to produce 375 tons of steel every six hours. Charging buggies, ladle cranes, scrap and limestone trains, all in constant motion, and not looking out for you!
@@rogerw-interested The world just didn't need that much steel. Let me explain how the old process worked: U.S. Steel had a stockpile of the most commonly used shapes and sizes of steel. If you needed something special, they would make it, but you had to pay for the entire heat. If you needed 75 tons you had to pay for 375. The remainder would go into storage. So... You call up on Friday and they say that they can make your heat on Monday. The heat is made and poured into ingots. It took two days for the ingots to cool down enough so that the ingot molds could be stripped. Then it was two days in the soaking pits at 2400 degrees to make the ingot malleable. Then the ingot was rolled into the shape you desired, and required a day to cool down. Ten days after your order your steel is ready to ship. Today's mini-mills, if you get the order in by noon your truck needs to be ready to pick it up by 3. The old mills never stood a chance.
I just went down an hour's worth of Wikipedia articles about US Steel and Carnegie and Pinkerton's and US labor history and steel production methods. Thanks! Was born in Pittsburgh but didn't grow up there
Whe did maintenance on a furnace transformer on site at a Smelter, it's got 6 big bussbars that is connected to other bussbars from the outside leading to the furnace, it's LV side was 66000 amps

It’s kinda weird to see the found from two different owners. The owner now removed all mini kilns, and pour stations. Just the giant one is left. I’m gonna get footage of it in the next month or so have not started yet due to a sudden passing in the family. But ya my bad off topic, but the heat in these places is hella hot, but the gear you have on keeps it hot around you, but shields a lot of the radiating heat. We have these suits we ca wear or arm guards , leg guards , torso guards , mandatory all boots have meta guards , and double splash guards. Also at that place the first time I was there I watched one of the aluminum injection machines Ice line leak, and into molten aluminum. We was 3 stories in the office when this happened. Was a pure white out, like this flash of light from the explosion made everything around us a pure bright white light. Legit thought we all passed at first. The machine just boooooooooom white everything for about 1-2 whole seconds. It scared me bad, I’ll never forget that ever. Legit sitting here in tears because the shit I seen that day. BAD days dude had molten aluminum go down his back, he was a normal injection machine operator or stacker not sure. But when it exploded since he was a average worker who is NEVER around pours ever he was just in the wrong place at the right unfortunate time. Melted straight through his back , and thighs. He lived, my uncle worked at federal mogul for like 30+ years. Told me a story they was moving a melting pot some line snapped the entire thing poured on someone I do not recall the story that was a long time ago.
It's actually not that bad. Not great, but if you wear long underwear under the uniform, it insulates from the heat and helps wick away the sweat. I worked at a mill, and the company gave us a couple pairs of a certain brand (which I can't remember the name of), and they were awesome.
The noise isn't even close to accurate unless you are standing there. You can feel it all through your body. They have a nice exhaust draw too. Where I worked it was seriously smoking at times.
Wow that brings back memories. I used to do maintenance on an electric arc furnace just exactly like this one at the Bradford Kendal foundry in Brisbane Australia in the 1960's

Y'know, looking at size and power of these machines, i can kinda of understand why the Mechanicus often times just pray their titans work. Think about it: a machine larger than a flat/small house probably littered with access ports and terminals for maintenance. And if its old enough it probably had plenty of modifications and jerry rigs though its service that makes the original schematics unreliable. And if thats the case theres no replacement parts, they arent produced anymore. Making repairs(and more jerry rigs) the only way to maintain it. It certaintly deserves some reverence.
I worked at constellium in muscle shoals Alabama . It's some really cool and dangerous stuff. A worker dropped his cup of water on accident into an aluminum furnace completely destroyed a building the size of Walmart in 3 seconds. Killed every person in the building instantly.
No chimney or extractors for the fumes? I remember visiting an arc furnace years ago, where the poor operator was sitting in his cubicle almost directly above the furnace, subjected to this acrid, poisonous smoke.

What is electric arc furnace dust? 1. Electric arc furnace dust generation is divided into three smelting stages: melting, oxidation and reduction. The amount of dust and pollutants in EAF are different in each smelting stage. In the oxidation stage, the furnace dust is the largest, and the furnace gas produced by 1T tons of steel is 80~100m3. The actual amount of furnace gas entering the dust removal system is determined according to the way of flue gas collection, which is generally more than 10 times larger than that of furnace gas. 2. In the melting stage, grease combustibles and metals in the charge are burned at high temperature to produce black and brown smoke. 3. The oxidation stage is the decarbonization process, and the oxidation of iron produces a large amount of russet smoke. 4. During the reduction phase, oxygen and sulfur are removed from the steel, and toner is added to adjust the chemical composition of the steel, producing a black or white smoke. The dust discharged by electric arc furnace is mainly air pollutant, producing 12~14kg dust from 1T ton of steel. At high temperatures in an arc furnace, metals are sublimed, oxidized, and cooled to form iron oxide particles less than 0.01 m. Dust and rust are discharged together with furnace gas. www.dancarbon.com/q/eaf/what-is-electric-arc-furnace-dust-hazardous-waste-217.html
Electric arcs in air burn the nitrogen and oxygen in the air to form nitric oxides which are powerful acids. The designers of these arc furnaces try to minimize this side effect by making the pot as airtight as possible. Nitric oxides in the air form brownish or reddish fumes. That may be why the smoke was brown at first as the air in the pot burned up....

When I started on the furnace floor nothing could prepare me for the sheer power, noise and heat coming off these machines, when melting down buckets the noise is so intense it shakes your entire body.

The actual amount of furnace gas entering the dust removal system is determined according to the way of flue gas collection, which is generally more than 10 times larger than that of furnace gas.
2. In the melting stage, grease combustibles and metals in the charge are burned at high temperature to produce black and brown smoke.
3. The oxidation stage is the decarbonization process, and the oxidation of iron produces a large amount of russet smoke.
4. During the reduction phase, oxygen and sulfur are removed from the steel, and toner is added to adjust the chemical composition of the steel, producing a black or white smoke.
The dust discharged by electric arc furnace is mainly air pollutant, producing 12~14kg dust from 1T ton of steel. At high temperatures in an arc furnace, metals are sublimed, oxidized, and cooled to form iron oxide particles less than 0.01 m. Dust and rust are discharged together with furnace gas. www.dancarbon.com/q/eaf/what-is-electric-arc-furnace-dust-hazardous-waste-217.html
Electric arcs in air burn the nitrogen and oxygen in the air to form nitric oxides which are powerful acids. The designers of these arc furnaces try to minimize this side effect by making the pot as airtight as possible. Nitric oxides in the air form brownish or reddish fumes. That may be why the smoke was brown at first as the air in the pot burned up....
A bunch of nasty ass shiiiied you don't want to breathe in is what it is
Iron oxide. The electric arcs vaporise the steel and it burns.
Taco Tuesday ??
So, this furnace was decommissioned?
