Abstract
A shaped, refractory, heat-insulating liner comprises particulate refractory material, a water-soluble borate compound and, as binder, starch and a urea-formaldehyde resin. The starch helps provide suitable transverse strength, the resin protects the starch from moisture and promotes good surface properties and the borate compound enhances the transverse strength and the integrity of the liner at high temperature. The article e.g. a slab is useful for lining metallurgical vessels e.g. tundishes.
