摘要
A highly reinforced refractory is disclosed. In accordance with the invention higher reinforcement of refractory shapes such as plunging bells or injection lances is achieved by infiltrating a bed of metal fibers in a mold with an aqueous slurry of a refractory material containing a superplasticizer. Refractory Concrete comprises e.g. calcium aluminate cement, alumina aggregate of 35 mesh or less maximum particle size, sulfonated naphthalene formaldhyde as superplasticizer and greater than 4 volume % metal (steel) fibers.
