Abstract

PURPOSE: To manufacture compact graphite cast iron with superior reproducibility at a low cost by adding a Cu-Zn alloy or a Cu-Zn-Sn alloy as a graphite spheroidizing inhibitor to molten cast iron together with a graphite spheroidizing agent.
CONSTITUTION: Molten cast iron 1 is poured in a ladle 2, and an additive capsule 3 is thrust in the molten metal 1 by means of a graphite plunger 8, melted and reacted with the molten metal 1 to form a compact graphite cast iron structure. The capsule 3 is prepared by packing a graphite spheroidizing agent 6 consisting of Fe-Si-Mg and Fe-Si in a container composed of a lower container 4 made of Cu-Zn alloy contg. 10W38% Zn or Cu-Zn-Sn alloy contg. 10W38% Zn and <38% Sn and of an upper container 5 made of low carbon steel. The Cu-Zn alloy or the Cu-Zn-Sn alloy acts as inexpensive elements inhibiting graphite from spheroidizing, so compact graphite cast iron can be manufactured at a low cost.
