Abstract

PURPOSE: To prevent occurrence of brittle rupture in a metal mold for centrifugal casting of cast iron pipes due to occurrence of heat cracks by making the mold of cast steel of a specific compsn. followed by hardening and tempering.
CONSTITUTION: A metal mold for centrifugal casting of cast iron pipes is made of steel contg. C; 0.05W0.22%, Si; 0.2W0.8%, Mn; 0.5W1.5%, P<0.04%, S< 0.03%, Ni 0.5W1.5% and V; 0.03W0.12%, By hardening and tempering the mold, occurrence of shattered cracks due to repeated thermal impacts is prevented. Accordingly, occurrence of brittle rupture due to propagation of the cracks is also prevented, and hence the endurance life of the mold is elongated.
