ABSTRACT:
Unfired refractory structural member in the form of a plate for the expendable lining of metallurgical vessels, especially for tundishes used in continuous steel casting, and comprising magnesia sinter and possibly olivine with a grading of 30-45% by weight under 0.09 mm, and 55-70% by weight 0.09 to 4 mm, including 20-40% by weight over 1 mm; cork or granulated ceramic fibers as a pore-forming material; an inorganic binder; and possibly other additives. This refractory structural member has good strength, a small ignition loss, a low content of volatile hydrogen-containing substances, a favorable peeling behavior, and good resistance to slag and molten steel.
