Pouring Well-Block
Cast corundum-spinel block that seats the nozzle in the ladle bottom. It sits at the sharpest temperature gradient in the vessel — steel on one face, cooling shell on the other — so its value lies in staying dimensionally stable there rather than cracking and loosening the nozzle seat.
