Abstract

PURPOSE: To obtain the product of superior quality free from any gas defect by letting the poured molten metal freeze under reduced pressure in the spacing in the upper part of the head part while a hot top system is being executed by using the mold which is of metal body at the outer side of the specific portions in casting of the rolling roll.
CONSTITUTION: A roll body 2 is cast by pouring molten metal into a mold 1 and right after the pouring, the top part of the mold 1 is hermetically closed by a cover 3 and the hot top system by heating of the head part 4 is executed. During this execution, the spacing part 6 is evacuated by the suction pipe 5 provided in communication with the spacing part 6 in the upper part of the head part 4 to the cover 3. At this time, the outer side surface of the mold opposing to at leat the spacing part 6 is made of metal body 7 so as to prevent the decrease in pressure reduction effect.
