Abstract
A refractory shape having improved resistance to erosion in metal melting vessels and high modulus of rupture, comprising an anhydrous refractory material, an anhydrous organic binder, from 0.3% to about 30% finely divided elemental carbon having a particle size ranging from 0.01 to about 1 mm, and from 0.3% to about 10% particulate elemental magnesium, based on the weight of the refractory shape. Addition of both elemental carbon and elemental magnesium results in a synergistic improvement in slag erosion resistance.
