Abstract: A refractory material for lining metallurgical ladles and the method of producing the same are disclosed. The material comprises refractory aggregate particles such as calcined flint clay which are coated with various materials including an outer coating of graphite which is covered with an elastic film of material such as aluminum phosphate binder. The graphite gives the refractory mixture the desirable properties and the film protects the graphite from oxidation and wear. The material is prepared in apparatus such as a pelletizer with an inclined revolving disk whereby the separate particles are each coated to produce a final mixture of discrete particles which are flowable and thus easy to handle. The refractory may be used as a monolithic lining or it may be formed into brick.
