Abstract
PURPOSE:To obtain the forged composite roll of superior surface roughening resistance and thoughness by plastically deforming the composite material which is obtainable by casting the outside layer of the high Cr cast iron material of the specific composition then casting the inside layer composed of the specific composition cast iron material to roll form. CONSTITUTION:The outside layer composed of C; 1.8-3.4%, Si; 0.3-2.0%, Mn; 0.3-2.0%, Cr; 12-26%, Ni; <=4.0%, Mo; <=4.0%, the rest Fe is cast, after which the inside layer composed of the cast iron of C; 1.2-3.8%, Si; <=2.5%, Mn; <=1.0%, Cr; <=0.5% and the rest Fe and further added with Ca; 0.10-0.60% is cast. The resultant composite material is plastically deformed to roll form through hot working such as forging, thence it is subjected to heat treatment such as annealing and stress relieving, after which it is machined to be finished to the roll of the specified size and shape. The addition of Mg; 0.04-0.10 in place of the abovementioned Ca and the inoculation of Fe-Si of 0.2-0.7% in Si% are equally well.
