Abstract
Molten metal handling vessels e.g. tundishes consist of an outer metal casing, a relatively permanent refractory lining and an inner disposible lining made of a plurality of slabs of refractory heat insulating material. Channels formed in the permanent lining adjacent the joints between the slabs or by rebates in the slabs are filled with refractory material, either preformed shapes or a refractory composition filled in situ. Such refractory material minimizes steel penetration through the joints between the slabs. The refractory material may contain carbonaceous material to enhance this antipenetration property.
