Abstract
Lightweight, low density magnesia-based tundish refractory compositions containing from 0.01 to 2.00 weight percent styrofoam beads and up to 5.0 weight percent paper fiber are disclosed. The compositions have excellent rapid heating, thermal insulative, vertical adhesion and deskullability properties. The compositions are useful as a lining applied over the permanent lining of a tundish, such as is used in continuous molten metal casting processes.
