Abstract: A roll and process for producing same are disclosed. This process includes the steps of: horizontally placing a core body made of a cast steel or a steel based Adamite containing from 0.5 to 2.5 %C, said core body having one or more circumferential grooves; feeding a consumable electrode wire into said groove or grooves, while rotating said core body, to thereby obtain according to an electro-slag welding process a deposited metal or metals filled in said groove or grooves, said deposited metal or metals containing from 1.5 to 2.5%C, from 0.2 to 1.0% Si, from 0.5 to 1.0% Mn, from 0.5 to 3.0 % Cr, from 0.2 to 3.0 % Mo, from 0 to 2.0 V, the balance being essentially Fe, and inevitable impurities; subjecting same to heat treatment at a temperature ranging from 500.degree. C to 700.degree.
