Abstract
A binder composition comprising pitch, an aqueous solution of a water soluble resin, and an organic solvent solution of a thermosetting polymer. The binding composition in combination with particulate refractory aggregate forms a molding composition suitable for use in making shaped refractory articles. Shaped refractory articles prepared from such a molding composition are particularly suitable for use as linings in basic oxygen process steel refining vessels. Shaped refractory articles may be prepared by coating coarse refractory aggregate with the organic solvent solution of a thermosetting polymer, admixing powdered pitch with the coated coarse refractory aggregate, blending fine refractory aggregate and the aqueous solution of the water soluble resin with the coated refractory aggregate-pitch mixture, and forming the resultant composition into shaped refractory articles.
