Well it’s 8:50pm got to be up at 1am no regrets lol

7:17am. Many regrets.

3:30am no ragrets

4:36

5am here

I used to do that job a long time ago with Repco Forge. The hammers were huge. The heat was unbearable. You sweat through all seasons.

@@mickcarson8504 I always wondered is the pay good!? I personally thought it would be, cause of the work and dangers. But hell I've worked dangerous jobs and been paid straight shit!!! Lol but for real wanted to know if it was good pay with benefits 401K plans insurance etc.

@@thatquietneighbor3637 I wonder this too

@@Crumbaa I mean right!?! They have got to be getting paid pretty good with hella good benefits!!! I googled it and it's good but I wanna know from a person cause you cant always trust that BS like I googled about machinist pay and it's all over the place and I got a buddy who gets paid $38 an hour and been there for 3 years and started at $30 off rip!!! I guess it depends for what type and the area ofcourse!!

@@thatquietneighbor3637 honestly I feel like they probably aren’t making anywhere near as much as they should. it’s the guy who’s up in an AC office with computer screens in front of him who is raking it in.

Things have been going up in prices since the beginning of time.

That's one of those things that separate us from the rest of the Animal Kingdom. There are many others of course.

Conservation of energy. We hear about it in school but it's cooler to see it in action

With how much force is the hammer hitting the metal ?

@@saitamabeatsgoku1960 I’m going to say about Tree Fiddy

About 90% get converted to heat, only 10% into plastic deformation.

Never thought of that, thanks.

Respect your safety concern for those poor workers. Their boss doesn’t care about them while counting profits and living in luxurious life

Yeah I was wondering if they added that section to show the difference of the hand forging versus their big machines, when I heard the voices I realize they had sped up the video as was my suspicion.

@@KA-pq3yz how would you know that? think of where this is and the fact every profession has got rules and regulation they got to follow and it seems to me most people who are in charge and got there by hard work like the ones they are are in charge over really do care for people now that's not the same for every situation but y'all always love to assume every rich guy or guy in power is only doing it for money and does not care about anything else a pretty naive way of think if you ask me perhaps even ignorant. You may be right but who knows respect all

@@gabrielrekt905 None of the employees wearing basis safety and protection gears in that video. Isn’t it so? That’s the telling point

I HEARD STEEL WORKERS, MAKE BIG BUCKS ? ? .

@Arthur Williams honestly it really depends. I feel those positions should make good money but a lot of companies take advantage

Same here. It’s hard work I’ve been at the place I’m at for two years and it’s a lot of work. We do both aerospace and semi wheels.

Due to regulation

how did you know i was here?

Just letting you know. That this is still happening. 2 in the morning, i'm watching a hammer hit some molten steel. KZfaq is a sleep thief.

You wouldn't feel much after touching the steel at least...

You don't have to be Chinese to work here but it helps, what?

@@johnhulsker9123 godzilla had a stroke reading this and died

Why would you think such arbitrary sick things?

@@ramonbril because I have intrusive thoughts lol

Right. This is fucking awesome.

Hardcore heavy metalwork

That is the first thing I noticed.

considering its a giant glowing piece of metal, yea.

Even a 20mm by 20mm billet of steel heated to 1000°C (forging temperature) can be really painful to be around.

How did you get the opportunity to see these up close? Inspection or something else?

We use to have a aluminum mill in our area that their electric bill alone was in excess of a million dollars monthly. Not factoring in natural gas use. Always found this stuff very interesting.

@@rodgerwoods4971 and people believe the windmills have the horsepower (or wattage) to heat or melt parts that big. The electrodes "wires" are anywhere from 6 to 14 inches in diameter just to conduct the necessary juice, and thats just one...

@@jeffwombold9167 Yes sir. And to deliver the amperage needed is massive. And as you stated, windmills, solar panels, etc isn't going to cut it. And the mill hammers are awesome. Not sure of the pressure used, but it makes easy work of it.

And how much energy they use to heat it up like that is insane I think

@@daan-6734 I don't think you are getting that heat out of a few solar panels on the roof haha.

I think also heat generated from deforming the metal with such force helps it to stay hot.

“Surface area to volume ratio” is the phenomenon at play here. As objects get bigger, their volume grows faster than their surface area. This is why a large chuck of stew can stay so hot for so long, there’s just a lot of hot steel and not much surface area for the heat to escape. This is also why the most efficient engines in the world are also the largest. As a cylinder gets bigger, you get a lot more volume (power) but not a lot more surface area (lost efficiency by losing heat to the water jacket)

Conversely, this is what explains the shape of heat sinks. All those fins create a huge surface area for a tiny amount of volume. So they are optimized to shed heat as fast as possible. The opposite of a heat sink would be a sphere.

Steel

@@jonathonvince561 Well, no, the steel has been made. This is about forging it into a product. Forging strengthens steel, eliminates voids and increases the homogeneity of the product, but regardless, this video isn’t about “making” steel.

They have to keep their hard hats on.

That's what blacksmiths call "scale". Basically, it's rust. The loss of material is very, very minimal.

The high temperature causes oxygen in the air to join with the steel surface much faster than it would rust the steel at normal temperature. So as the steel cools, the scale forms more slowly. Yes, the loss of scale is small but an expected part of the process. Remember that most forms of iron oxide are many times less dense (take up more space per gram) than iron itself. Usually at least one surface is machined to an exact dimension after forging, sometimes the entire surface of the part is machined, mostly depending on which surfaces touch other parts (but also for cosmetic reasons if a customer can see the surface). So the requirement is to leave enough metal to cut the rough "as-forged" surface away, not to forge it to the exact final dimension ("net-shape").

@@elektro3000 Great explanation.

Slag

Impurities in the metal

I’m pretty sure it’s used to prevent the steel from sticking to the pin

Mostly graphite.

@@francescopaolociminale5258 Hot forging is sometimes dangerouse, and the large forging in the video is a high－risk industry. But the development of automated machinery can keep workers away from danger.

I do _not_ work at a forge but I _was_ wondering; what is the deal with the stuff that falls off the side of the nugget when it's being squashed? 1:02 🤔

@@wavydavy9816 I think it’s like how sometimes on rail pieces of it will chip of and heating it up accelerates the process

i dont work at a forge but i love seeing heavy machinery at working with humans

I do work at a forge, but I just saw hot metal on the picture and clicked.

Love your comment. They are traits that can accomplish so much but that also have the potential to destroy much more.

Thank fuck I’m not the only one who wanted to eat it

Not much.. It will sink deep and all the vapor will condense on the way to the surface. You MAYBE find some unusual warm water on the surface, but that's it.

@@jackmclane1826 If you dropped on the size of a house maybe you’d get a reaction chain of fire and flames in the water. But besides that it would all disappear in less than a minute or so. First the ocean is pretty cool or cold in some areas. Second this is steel and no matter how big the object it still will cool down rather quickly. Poor fishes though

@@spartanalphamode2987 I'd disagree to the cooldown speed. The Leidenfrost effect will cover it in a layer of steam and insulate it for quite a long while. Certainly in the range of several minutes. Of course it depends on how deep the water is, because of the pressure that would hold down the steam.

Depends on the wattage needed. The trick with Green Energy is to use it to pump water up hill into a lake and let it out over hydro. $0.03-$0.05 kilowatt.

What about geothermal? Use the planets’ heat. Tap a volcano.

@@radwizard Fair point - I was involved in pumped hydro storage many years ago. Do-able for domestic, if you have suitable terrain but crikey, for large industrial? - they need to operate 24/7 so that would need a serious solar/wind set-up...

@@bryanreidsands6854 Indeed, I think they make use of geothermal sources in Iceland - but I doubt they'd license a major industrial plant. Incidentally, some recent engineering news states that China is about to commission its first thorium molten salt reactor. Now that really is a game changer. Just a pity the west has sat on that technology for over 50years!!! (I doubt it will get a mention on the MSM)

A lineage of smaller machines going all the way back to the first human who figured out that you if you placed this shiny rock in a fire, it would melt out a substance that was harder than the rock that it came out of and could be shaped into useful things.

It's not, with bad tools you can make better ones. A hammer can be forged with stones. It won't be a good hammer, but it'll allow you to make a better one.

Casting. Then improving to forging. My quess.
