Molten Steel Shoots Up - Cobble EXPLAINED

Have you ever wondered why molten metal sometimes shoots up at a factory? Well, it’s actually hot steel, and this incident is known as a cobble. When hot steel is being shaped into beams or rebars, it passes through rollers that squeeze and stretch it to the desired shape. However, sometimes due to mechanical failure or improper handling, the product deviates from its intended path, getting tangled or jammed, causing it to launch. And if it lands on someone, they will instantly become Cast Iron Man.

Instructions weren't clear. Now I have a cast but I'm no cast Ironman

Working in a factory where lightsabers are flying around?...

No thanks. Lol

My mom works at one of these steel mills. The amount of cobbles they've had and videos she's shared with me is crazy. Always respect steel mill workers. There are so many more dangers than just that hot metal

"have you ever wondered why molten metal sometimes shoots up in the air in a factory?" ...No? I DIDNT KNOW IT DID THAT?

That guy who caught that molten steel and directed into the other mold has balls made of steel. Highly skilled and made it look effortless. Respect.

Cast Iron Man😂. Sounds like an Indian Avenger.

Was a witness to this on a field trip to the steel mill in elementary school. Following that no more trip were ever planned to go back.

I'm an electrician and whilst working at a steel mill-I felt heat on my back. As I turned I had a giant cobble falling towards me-moved just in time-It woulda killed me!

You know i dont think i have ever wondered why molted metal shoots up into the sky.

[robwellborn]

I spent 32 years in a steel mill, and have seen this happen many times, until you experience it in person you just can’t appreciate it

[paulbuckley]

Yes! I have always wondered exactly that! You know, whatever you just said.
Keeps me up at night!

The Silly String Steel hanging in the rafters was epic.

[latinouss]

I always wonder that, like day and night. I wake up in the mornings and the first thing that I think about is why molten metal flies all over he place. Thank you so much for resolving this mystery

In the summer between high school and college in 1970 and the following summer I worked in at Interlake Steel near Chicago as laborer. The mill rolled the steel used for highway guard rails which is relatively high carbon steel. 2” thick billets would be heated in a furnace then passed several times back and forth through a single roller ‘roughing mill’ which would reduce the billet to 3/4” thickness. It would then pass through the ‘finish mill’ which consisted of six rollers, each turning faster than the last because the speed of the steel ribbon increased as it got thinner. The operator of the finish mill had six levers he used control the speed and if he screwed-up the steel ribbon would accordion between the units of the finishing mill in a ‘cobble’. An alarm would sound and that was my signal to suit up report to cut it up with three-foot long an oxygen-acetyl torch.

Since there were two billets being run at the same time a ‘cobble’ in the finishing mill would result in a still red hot billet being worked on in the roughing mill. That required reaching across a two feet of red hot steel with the torch to cut in to sections the overhead gantry crane operator would drag onto the floor along with the cobble from the finishing mill to cut up. The cutting of the red hot steel from the roughing mill was done mostly by triggering the oxygen supply of the torch but if you applied too much or tried to cut too fast the high carbon steel would splatter.

Drake: "was that metal?"

[juslewissr]

"Cast Iron Man" sounds like the Dollar General version of Iron Man.

[saintgein]

I can’t imagine the pain or death that would result of liquid molten metal falling on you. Oh my god

[BlankBrain]

If you work in a rolling mill, you learn to wait for the leading edge of the steel to go past before crossing over a cooling bed. The mill I worked in had huge spinning blades between roll stands that cut the rest of the billet into small pieces if there was a cobble.

I dont want this day to go by without me saying to anyone who is a metal smith. Thank you for your work!!!!

The steel becomes possessed by angry Italian chefs and proceeds to create angry spaghetti
