ABSTRACT:
A vessel for holding high temperature bulk materials, such as a ladle for handling molten metal, includes a steel bucket containing a permanent outer layer of refractory material. Within the outer layer is an expendable layer which is made up from relatively rigid boards of compacted microporous thermal insulation material. Within the layer of microporous thermal insulation material is a further expendable layer of refractory material which covers the inner surface of the layer of microporous thermal insulation material. The thermal capacity of the expendable layer of refractory material is preferably less than the thermal capacity of the permanent outer layer of refractory material.
