Not folded yet. It would need to be bathed, or maybe showered in gold to be a real valid currency.

A whole bunch of stuff

Industries such as aerospace, oil and gas, power generation, heavy equipment, automotive, mining, and marine often specify seamless rolled rings for components requiring strength, durability, and reliable performance under high stress.

Specifically, any part that is vaguely this ring shape will probably be stronger and cheaper when machined from a rolled ring rather than cutting it from a solid plate, since there’s a lot less material waste and the process of rolling actually produces some favorable properties in the microstructure of the material. Plate is generally faster though, since often there won’t just be a rolled ring on the shelf in a size you need and custom orders take some time.

Don't be ridiculous. Why would an ent need a cockring? He's already made of wood

u/supernova-juice 7h ago

I wonder if that Wicker movie is any good?

7

u/inio 2d ago

My guess is this will be machined down into a ball bearing race or something similar. They'll end up removing 70% of what's here, but that's a lot less than if they started with a solid billet. The shaping process probably also has beneficial metallurgical side-effects (grain shape/size/orientation).

Look at how they make seamless tube.

Manufactured to very exacting tolerances.

u/raskulous 2d ago

It would get machined to tolerance after

u/Mysterious-Tackle-58 2d ago

I'm always wondering.
All those vids with the big punchy thing and the chisel thingy getting hammered inside.

How is this precise enough for anything?

34

u/spunkychickpea 2d ago

What you’re looking at isn’t even close to the final product. This just gets it to roughly the correct dimensions and then it’s machined further to get it to the precise shape and dimensions.

18

u/NavierIsStoked 2d ago

So, you can make a part 2 ways.

The first is to get a mold to exactly the shape of your final product, liquefy some metal and pout it in. It will be a very brittle part. The crystalline structure of the metal will be all over the place.

The second way is to pour you liquid metal into a very generic shape, either a bar or a cylinder or something. You then work the material into another basic shape. The working aligns the crystalline structure and creates a much stronger part. The idea is that your work the shape into a blank that is big enough to encapsulate the final part. You then take the worked blank and mill off the material until you are at your final shape. Then you heat treat the part and treat the surface.

u/Mysterious-Tackle-58 1d ago

Thank you for the explaination!

Let me get my bent science ruler and wave it generally at the item.

I assume this checks a procedural box of "measure at this phase before moving on to the next"

u/AbueloOdin 2d ago

Super neat. It spins and expands on the first point until the second point constrains it. Then expands from the first and second point to the third point.

And of course, 3 points define a circle.

So you get consistent outer diameter manufacturing of a steel rings.

3

u/PmMeUrTinyAsianTits 2d ago

Inner peg means the inner diameter's gonna be pretty consistent too.

1

u/AbueloOdin 2d ago

Yeah. Most of your deviation is going to be width.

Not one aerobee reference?

u/maxxdreddit 2d ago

Don't worry, it's quite cool.

7

u/AboynamedDOOMTRAIN 2d ago

What even is the point of measuring the diameter with that mangled ass looking meter stick?

11

u/Superbead 2d ago

They'll just want it approximately the right size. It'll be accurately machined afterwards

3

u/Agent_Orange81 2d ago

Ok now I have to know - looking at the color gradient in the finished item, the inner face glows more yellowish and the outer is red - is this just a matter of differential cooling or does the change in color reflect a material change as well?

5

u/DJBFL 2d ago

That's because it's getting worked not just on the inside diameter, but also on the face. The roller the ring is sitting on has a notch. At the end, the expanded ring is thinner in the yellow section than in the red section and it's hotter because it got squeezed more. Notice the light reflecting off the step at the 6:30 position.

1

u/Agent_Orange81 2d ago

How does this affect the hardness of the product, is the inner face softer than the outer? It's been a LONG time since I fell asleep in a University materials Science class 😅

Any time I see red hot metal, I want to get a hammer and start hitting it. Anyone else?

I've always wondered what the expansion of a red-hot steel ring during the hot ring rolling process looks like. Thanks for this.

u/Big_Mudd 2d ago

Does anyone know why it's asymmetric? The wheel on the right is closer to the ring than the wheel on the left, and makes contact with the ring well before the other.
