It’s weirdly enjoyable to see a giant block of steel get squished and shaped into a giant roll of steel by giant machines. Seeing the hot flakes fall off, seeing a square slowly get squeezed into a circle, it’s something I can watch for a very long time. These steel rolls were made by the Forging and Press Plant JSC-Ruse.

I never did well in science, so this is probably a stupid question: what exactly are the flakes which fall off? Is that metal which is just considered useless? Seems like it wastes a lot if it is.
