On the furnace I operate we start our melt down with the roof in the up position for around 2 min to save the roof from the arc. It makes one hell of a spark show and is loud as hell !!!
You guys should see how we make 99.99% silicon metal up in Niagara Falls New York. Our electrodes use more power than 2 Sears towers combined. Thank god for Niagara Falls hydro power.
1535°C depends on elements in steel, i worked with steel which start it's solidification near 1300°C. Less steel needs element in its conposition, more you have to heat.
1300°C is almost finished process of solidification, 80-120°C below it's optimal heated zone for forging.
I'm working and studying metallurgy of steel for 5 years and I haven't seen 1300°C liquidus temp of steel. On all diagrams are mostly 2 phase at 1300°C.
@2jzgtejza80 I worked 2 years in steel factory and in fundery. i was process technician and had to solve process problems due to solidifications of differents steels. A very rich work experience. Unfortunaly, i must not give more details or which kind of studied alloys .
But if you find articles or notes on web, you will be surprised about several steel processes in the world. Therefore, i am sure on what i said.
4160 volts on the electrodes. Atlantic Steel in Cartersville, Ga has to call the coal power plant down the road before they startup. If they don't, it will brown out most of North Georgia ! Some serious current !
Looking this video remind me when we were working at DANIELLI Steel factory, and ACINOX Cuba, for many years, I'm proud of be part of their team and proud of all Engineer and Hardworker working in this dangeous but amazing field,
actually he's trying to burn out any SOLIDIFYED steel that could be obstructing the bore. If not, i would have to come kick his ass for turning the caster around!!!
They should put public viewing galleries in places like steelworks. Beats most of the crap you get on the telly these days. There arent many steelworks left in england anymore, though. Not proper ones with blast furnaces like Consett and Ravenscraig, anyway.
man man man legt das teil los arbeite auch abunzu mal an so einem ofen aber glaub isn spielzeug dagegen^^das is bestmmt ein 30 er bis 50er tonnen ofen( das is ne maschiene^^XD)
that is even more yet. I am sure the money due to the danger of the heavy equiptment is worth it. we have several steel mills around north east indiana the biggest being steel dynamics, and metal technolagies formarly called auburn foundry. There is also a nucor building systoms shop just north of auburn.
how loud in decibals of sound is it, and how long do you have to juice the furnice like that to melt down a fresh load of scrap. It would be very nerve racking to have to put up with it for very long, and does it always make the loud booming even when its almost done melting the metal?
Well, I can say this, It's insanely LOUD!!! Without plugs it will rattle ur ear drums! I work in a "mini-mill" and i'm only about 70ft away from our EAF/LMF. I have to listen to a 200Ton EAF 12hrs a day! It's very hard to operate my caster hearin' one of these fuckers! Typically, we can achieve our max Mw for tapping in only about 35-40minutes post the inital header charge/back chrg. At around 30minutes in,(40Mw)You have meltdown then the EAF will hum like crazy till you reach desired tap-temp.
man you have to hear the banging for thirty minuts? Man that is nasty. and you have to put up with it twelve hours. I would get annoyed real fast from that. It runs 40 Megawatts? that is a ton of juice.
Is it at least less polluting then a Blast furnace that runs without stop for years on end. Well thank you for the information
You're welcome. And btw,..Yup, 12hrs in the same shop!! This thing actually creates many operations/mental issues with us all. It sucks! But the money and job knowledge is great to have though..LOL! And I'm sorry for the error in the previous post. Our EAF normally achieves about 57Mw before the operators can start the tapping process. Also,The EAF creates very little,if any pollutants,except for your lungs,of course.Apparently,"OSHA" refers to this as K/O 61 dust. :)
I work on the same type of furnace and the electric arc is so strong that on the midnight shift the light from the arc went out the large department door and you could see a square lit up on the hillside across the river.
Looks like a 100 ton arc furnace. I work at a BOF melt shop and had the opportunity to transfer to an electric shop for 3 months. The noise these furnaces produce will literally rattle the teeth right out of your skull. lol
I've been at a furnace few weeks ago. And stood maybe 20 metres before, just like the camera. It was astonishing...never ever seen something like that...when the electrodes went in, that was scary...
i worked for a year as general labor in the furnace dept at northwestern steel and wire. been on top ,inside,and underneath the furnaces. hot as hell in the summer and cloder than the arctic in the winter. one has to be aware at all times if not one could be dead..the money was worth it..
Fantastic. Awesome power. Could snuff you out in an instant. Great respect for the guys who operate these monsters. I remember seeing the 6 150 ton arc furnaces of Steel Peach and Tozer's electric melting shop at Templeborough in Rotherham in action. Brings back the memories. Thanks a lot
YES, 3150 to be over 2800 in ladle. Lots of variables. Transformer size, electrode size, tap hole size etc. We are an all Stainless shop and it is a little easier on slag line. We also bank and gun to extend life. Slagline reline every 6-7 wks.
@SlagPotCarrier88 Close but wrong. steel Melts at 2700 and we tap at around 3050 to 3080. Anything over 3120 and You better get that heat out of the furnace. If your Carbon is flat and your over 3100 say your prayers when you drop your 34 to 40 bags of Coke at tap !!! lol

@Maloner78 yes. It's depend on sorte of steel you are making. between 1400-1600°C

@llaenael
Mostly 1640°C for low-mid carbon steels. 1710°C for mid-high alloy steels.
Below 1535°C begins solidification phase.

I was offered several jobs to say on the mills.
I left to work for G.M. in TEXAS . Got hurt there.

but an arc furnace can reach 3000 degrees max.
