摘要

Improvements in the construction of devices for manufacturing a refractory rod in a crucible, of the type comprising a metal casing that forms the external wall of said crucible and a hollow nucleus of embringement mounted axially in said casing, the remaining space being filled free between said core and said casing by a refractory material, characterized in that said core directly contains vibration means, which effect the caking of said material.
