FIELD: ferrous metallurgy. SUBSTANCE: method involves producing cast slab by electroslag remelting process; forging roll neck part at deformation extent of 45-55%; providing surface quenching in inductor with current of 2,000-3,000 Hz frequency. Method is used for production of rolls used in hot rolling mills. EFFECT: increased efficiency and improved working strength of rolls. 2 cl
