I used to travel as a journeyman electrician and sometimes I would work on steel mill shut downs and turn arounds. I would always work on the EAF if I could. 40,000 amps at 600 volts supplied to the 30 ft long carbons by water cooled cables as thick as your leg. No matter what job I had, when the turn around was over, and they started the EAF back up I would be there to see it because there is nothing, man made, like it in the world. unreal power. 100,000 pound lid on the pot bounces around just like it was the lid on a pot on your stove top when water boils.

Thanks for the info & figures, as since a EAF came up in my feed 6 months ago & shocked the sh¡t out of me with how frighteningly impressive they are, I've watched plenty since & you're the first to fill me in on how much anps they suck etc! They'd probably use enough power in less than a minute, than what would run a house or small business for a year?! I wonder how on earth to the steel mills pay the electric bill?!

@@milind006 You are correct, the transformer is right by it, hooked up with giant water cooled busbars and cables in sets of 3 per each phase, usually the primary voltage to the transformer is around 33 kV or so at about 1500 amps. There are tap changers on the primary to get the fine power adjustments. The transformers are ridiculously big, and force cooled with oil to water heat exchangers.

In the early 80s, I worked in a forge that made train wheels, CSW (Canadian Steel Wheel) in Montreal. There were two electric arc furnaces each producing 90 tons of molten steel. The two furnaces worked alternately to supply the forge's needs for steel ingots. The noise was insane despite our hearing protectors, but so was the spectacle offered by these mega machines. The forge's 7 hydraulic presses then took over to shape the reddened steel ingots into the shape of a train wheel. Imagine flattening a block of steel 2 feet in diameter by two feet high, just as easily as you would flatten a ball of ground beef into a hamburger patty. Finally, the forged wheel went through various machining steps to give it the required dimensions.

Guillermo asked how they limit the current. As Rodal said, the arc rods are lifted in and out to keep as near constant current as possible, but when going into a load of raw scrap, short circuit currents are limited by the impedance of an over-winding or choke on the mains transformer. In my day, post WW2, the noise and fireworks were spectacularly enhanced by melting bomb and shell cases from which not all, or indeed, none of the explosive had been removed.

Ahhh 😊 that scary sound of a 50Hz arc furnace that made everything vibrate. First time I see it, it scares the shit out of me 😱And I'm guess it'll do the same for pretty much anyone the first time they whiteness it. I thought to myself "Is that supposed to sound like that or is something about to explode?" When you work at a steel mill you'll look up n see massive hole and gouges in the ceiling and walls. You ask the first time n then after that, you don't bother because something exploded. ToT knows what I'm talking about. It ran at 900V at 60KA n they used vacuum breakers for obvious reasons. I couldn't even imagine the size of the vacuum breakers n how many of them there were 🤔 I worked there whilst it was being refit and when it was running and we were mostly doing lighting. They had a fair sized steam/chemical cleaner in the workshop which came in well handy when you found a fitted that that'd been sitting in oil, greas n other nasty stuff. The blokes in the workshop had enough of us cutting uni-strut as it was fucking there blades up. But some told us where there was another one n that blade needed changing as well. I'm not sure why though as they cut things in the work shop that are a lot harder than uni-slut. Before that we were using a metal cutting disk cutter. Other people kept using it to cut wood n kept fucking the blades up, even though we had to get it from the office n the people who kept using it to cut wood got a bollocking. I missed working at sheerness steel. I almost got crushed by an overhead gantry crane whilst being there. It wasn't the drivers fault, as no one told him that we were working up there at the end putting light up so it can get a service. Worst thing that happened is there was a bloke who worked there who didn't like me and was doing his best to brown nose and I was holding up a bit of uni-strut n he said he was just got to tack it, but ended up welding pretty much most of it until I pulled my hand away n my glove was melted to my hand as all the splatter dripped onto my hand. I think he got a word in his ear and I never worked with him again thank fuck. I've never brown nosed and I never will. If I like my boss than I'll be nice to them, but that's it. There was one bloke who we use to call "toe nails". Because he was so far up one of the bosses arse, all you could see what his toe nails. Anyway They didn't quite understand health and safety there for some reason. If someone had an accident, they use to pay them sick pay so the heath and safety work record was brilliant! When you went to the stores to get bits, you ask them how they lost a finger(s) or loose an eye n other bits. There are also some other terrible incidents that happened there. One of which involved the cooling down rollers for bar stock (that machine at the end which rolls it up is amazing). 😳 He did survive btw, but only because the bar stock was hot 😕 Poor bloke Look up "steel rolling mill" and you can understand how dangerous that machine is 😱 One of our joys was to supply the 10 fans blowing up air and one of our other jobs there. Was to supply a 6MW motor which had 10x 3x240mm supply it. The plinth it was sitting on was the size of a house. When we were dragging the cable in. At one point, me and someone else was in a forklift cage. People behind us didn't hear stop and the cable pushed me out of the cage so I was only holding on to the cable with an 8m+ drop. The forklift operator see what happened n dropped the cage down n put me back into it and we carried alone as per usual. With the people behind taking a bit more notice when someone said stop!! Sorry for the rant. But I could go on and on and on about how dangerous a steel mill is.

My grandpa said when he worked in the mill, he used these and holy crap were they loud. More like D.E.A.F furnace.

From 20 feet away it's like a shotgun right next to you every time an arc strikes. Wear ear protection and still loud as shit. Don't even try to talk to anyone, it's only lip reading and hand signals.

Direct Iron ore Reduction also can provide good "feed" and Australia is well positioned for that - we just need to turn around and turn the flood for that.

Its an extraction system, the pipe sucks most of the fumes/dust etc out of the furnace.

Been in a steel mill just like that on the Louisiana Mississippi border. Very loud, extremely hot, very dirty and scary!

The chiming sound is most likely the alarm for the overheard crane setting down the charge bucket. The liquid falling down the electrode is simply water to keep them cool.

@ramjetrabbit - The EAF is a relatively cheap and fast way to turn scrap metal into rebar or light structural steel. There is typically a 110 kV line from the power plant to the switchyard at the mill, where a step-down transformer takes it to 34 kV for local transmission. The biggest tie coming off the substation is the lead to the primary side of the EAF transformer, which steps the voltage back up so that an arc can be struck.

They were also losing $2 million a week back in 1997...Blamed it on Scrap Prices and the sagging economy for American Steel. Personally, I think it was a dismantling on purpose by poor management. By my understanding, now Sterling Steel (Leggett and Platt) is actually MAKING money. It certainly helps that they run the furnaces at night and on weekends when power use is markedly lower. It's not like Sterling will run out of power when they're serviced by Byron Nuclear anyway.

Wow, that's a lot of power right there. I assume the three rods mean it's three-phase AC running through them?

Yes. About 45 megawatts there. Terrifying when that much power is released in such a small space. Arc furnaces are wonderful things, though. They produce a high quality product and can be run on renewable power: melt 40 tons of steel without burning fuel and generating CO2. Whoo hoo!

I think that's an exhaust port which directs alot of the heat and energy out of the crucible.

I got to see an EAF in operation when I took a tour of Nucor Steel's operation in Seattle. The furnace had three times the capacity of this one, 40 tons per charge at 120 tons per melt. It sounded like magnum rifle calibers been shot off in that building when the electrodes arced!!!!!!!!!!!!!!!

Awesome. This was actually more entertaining than most of the motorcycle stunt and music videos I watch. I especially liked the part when the electricity starts.
