Abstract

PURPOSE: To produce a roll of superior surface roughening resistance and abrasion resistance by increasing the number of revolutions of chillers in such a way that the gravity multiple that the cast roll receives by centrifugal force at the extreme surface during solidifying assumes specific values in centrifugally casting the roll made of adamite as its outside shell material.
CONSTITUTION: The number of revolutions of chillers of a mold is increased and molten adamite is solidified, in such a way that the gravity multiple that the extreme surface part of the roll receives during solidifying at the stage of centrifugally casting the adamite having the composition 8.8W2.2% C, 0.3W1.2% Si, 0.3W 1.2% Mn, 0.3W2.5% Ni, 0.3W2.5% Cr, 0.3W2.0% Mo, <0.1% P, and <0.1% S as its outside shell layer attains 120W200 when calculated by the equation[I], whereby the roll is cast. The surface roughening resistance and abrasion resistance of the outside shell adamite of the roll are improved.
