Nuclear Reactor Rings: How Seamless Steel is Forged
How are massive, seamless metal rings for nuclear reactors made, and why can't they have a single weld? In this episode of Made on Earth, we travel to the heart of a metallurgical giant to witness the birth of a 90,000-pound steel masterpiece.
Watch as a glowing 2,200°F steel ingot is crushed by 100,000 tons of hydraulic force — a pressure equivalent to Mount Everest stepping on your breakfast. We’ll show you the entire ring-rolling process, where multi-ton cylinders stretch red-hot metal into 33-foot "donuts" with surgical precision.
