This hot piece is placed on a rolling machine where rollers press and stretch it in a circular motion. The hole expands and the outer diameter grows until the ring reaches the required size. After rolling the ring goes through heat treatment for strength then machining and finishing for accurate shape and smooth surface. This process

It involves the controlled use of explosives to fracture and displace rock, making excavation faster and more efficient. 🔹 Why We Use Blasting: 1. Rock Fragmentation: Blasting break

Scientific American on Instagram: "This year’s Nobel Prize in Physics went to three people who helped discover that a quantum physics principle works on real world scales. Their findings helped form the basis of digital technology, including supercomputers and smartphones.

Quantum Explained on Instagram: "How Fast Can a Black Hole Move? Faster Than Light? Description: Black holes are some of the most mysterious and powerful objects in the universe. But do they actually move, and if so, how fast? According to physics, nothing can travel faster than light (299,792,458 m/s). Yet black holes possess such intense gravity that not even light can escape their pull — making them appear completely dark. Some black holes can drift across galaxies at thousands of kilometers
