摘要：A composite and monolithic refractory structure, particularly adapted formaking furnaces for glassmaking or the like, constituted by a block- shaped componentmade of electro-cast refractory material based on oxides of aluminum, zirconium, silicon,and the like, having shapes and dimensions that are adapted for its uses, inside which atleast one protective element is monolithically inserted; the protective element is highlyresistant to the attack of molten glass baths or the like and is chosen among metals,noble metals, refractory metals, refractory materials, conventional and non-conventionalceramic materials, such as carbides, nitrides, borides, and the like, or graphite-basedmaterials, alloys and/or compounds and/or composites thereof; the element is providedsubstantially in the shape of a plate that is shaped and sized so as to have a profile that issimilar to the peripheral profile of the refractory block and is arranged, inside the block,so that its surfaces are located at, and proximate to, the surfaces of the block that aremeant to be exposed to the attack of the bath, so as to constitute an insert that acts as acontinuous protective barrier against the attack for the refractory component. The scope

of the invention also includes a process for producing the composite refractory structurein conventional molds.
