Abstract
PURPOSE: To cast a cast iron product contg. partially distributed spheroidal graphite by pouring molten cast iron so treated as to form compacted/vermicular graphite in a mold with a graphite spheroidizing agent set at the necessary part.
CONSTITUTION: Molten cast iron so treated as to form a compacted/vermicular graphite structure contg. about 0.01W0.02% residual Mg by reaction with an Mg- base graphite spheroidizing agent is poured from the sprue 3 of a mold composed of a cope 1 and a drag 2. At this time, an Mg-base graphite spheroidizing agent 6 is set at a position from which molten cast iron enters the part 4a of the casting space 4 of the mold requiring strength. Molten cast iron reacted with the agent 6 is poured in the part 4a to form a spheroidal graphite structure with superior toughness, and in other part 4b a compacted/vermicular graphite structure with superior wear resistance, damping capacity and machinability is formed.
