Abstract
A mandrel for continuous casting of hollow ingots comprising a hollow rod having a collar and a tapered portion thereof introduced into a mold cavity. Mounted on the collar is a protective sleeve axially movable along the rod under the hollow action of a drive mechanism. This makes it possible to eliminate the possibility of bridging formed in the continuously cast ingot in the event of an emergency.
