Abstract
PURPOSE:To produce the rolling roll of dense surface structure by drawing the cast ingot having undergone electroslag remelting to let the direction of solidification structure approach to the angle perpendicular to the axial line of the roll then molding and forging the same to a roll shape. CONSTITUTION:In the cast ingot having undergone electroslag remelting, columnar crystals having a fixed angle depending upon solidification characteristics have grown. Consequently, the directions of the columnar crystals is corrected, particularly in the surface layer part, by drawing and is approached to the angle perpendicular to the axial line and at the same time forging effect is given. In the position extremely close to the surface, the correction becomes excessive and reverse inclination is given but this portion becomes the portion to be turned in later machining. After the drawing, the ingot is molded and forged to a roll shape, whereby the rolling roll is produced.
