Abstract

Monobloc type durable rolls of over 10000 kg have been developed by ingot metallurgy for hot rolling mills, and the metallurgy and the manufacturing process of the roll are described. The microstructure of the roll consists of hard primary carbides, mainly vanadium rich MC, embedded in the highly tempered matrix. The characteristics of the roll which relate to the performance expected for a durable roll are also explained.
