Abstract
A vessel used for containing molten metal has a refractory liner with an exterior surface and a metal-contacting interior surface and is made of at least two refractory liner units abutting at a joint. A housing at least partially surrounds the exterior surface of the refractory liner with a gap present between the exterior surface and the housing. Molten metal confinement elements, impenetrable by molten metal, are positioned within the gap to partition the gap into a molten metal confinement region between the elements and at least one other region. For example, the other region may be used to hold equipment such as electrical heaters that may be damaged by contact with molten metal. A drain outlet positioned in the housing allows molten metal entering the gap to drain out of the gap at the drain outlet.
