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.

A refractory shape comprising a refractory concrete reinforced with greater than about 4% by volume of metal fibers said concrete containing a refractory aggregate having a maximum particle size of about 35 mesh or less. A process for reinforcing a refractory shape which comprises: (a) preparing an aqueous slurry of a refractory concrete containing refractory aggregate having a maximum particle size of 35 mesh or less and a superplasticizer, (b) placing a bed of metal fibers in a mold, wherein said bed of metal fiber is about 4 to 20% by volume of said mold, (c) adding said slurry to said fibers while vibrating the mold such that said refractory concrete fills said mold and uniformly infiltrates said bed of metal fibers, (d) allowing said refractory concrete to harden, and (e) drying the refractory shape obtained.
