Abstract: A laminated steel mill roll consists of a core member, a reversible replaceable shell member and a retaining member. The core member has a radially-outwardly extending shoulder, while the shell member has two symmetrically-disposed radially-inwardly extending shoulders, the core member shoulder engaging one shell member shoulder for location and retention of the shell member on the core member, and the retaining member fastened to the core member engaging the other shell member shoulder. The shell member can be made as two similar reversible replaceable portions, or as a plurality of such portions at least the two endmost being similar to one another, giving even greater possibility for interchange and increase in useful life.

Abstract: A reinforced ferrous metal casting and a method of making a reinforced ferrous metal casting wherein the reinforcing rods are located within tubular metal sheaths such that the metal sheaths become fused and bonded to the casting while the reinforcing rods located within the metal sheaths are not fused with respect to the sheaths and are, therefore, slidable within the casting. The reinforcing rods are preferably spaced from the sheath by a refractory coating.
