PURPOSE: To improve heat insulating performance and refractiveness and to prevent casting defects by using a fiber material to form at least a part of the refractory aggregate of the facing material consisting of the refractory aggregate and binder. CONSTITUTION: The refractory aggregate is mixed with the aq. soln. added with the binder and the fiber material is added as a part of the aggregate to the soln. to prepare the facing material for forming a facing material layer 3 on the inside surface of the cylindrical metallic mold 1 for centrifugal casting. The binder contains at least one kind among bentonite, KIBUSHI clay, sodium aluminate, water glass, and colloidal silica. The fiber material consists of at least one kind of the fibers of silica, chamotte, mullite, alumina, zirconia, carbon, silicon carbide, calcium silicate, potassium titanate, etc. The aggregate is the refractory particulate matter consisting of at least one kind of alumina, zircon, silicon, oxide, chromite, mullite, ...
