Abstract

PURPOSE: To surely manufacture spheroidal graphite cast iron in a high yield by introducing molten pseudospheroidal graphite cast iron into a mold through an intermediate chamber holding a graphite spheroidizing agent.
CONSTITUTION: Molten pseudospheroidal graphite cast iron is introduced into a mold 1 from a sprue 2 through a strainer 3, an intermediate chamber 4 a runner 5 and a gate 6. At this time, a graphite spheroidizing agent such as an Mg alloy or a Ca alloy is put in the chamber 4, and in the chamber 4 the pseudospheroidal graphite is spheroidized. The spheroidizing agent is used by a small amount such as about 0.1W0.3% of the amount of the pseudospheroidal graphite cast iron.
