Abstract

PURPOSE: To easily manufacture a CV cast iron casting of stable quality by melting starting material pig iron contg. C, Si, Ce and Ti or contg. further Cu, Mn, Sb or Sn, inoculating the molten iron, and pouring it.
CONSTITUTION: Pig iron consisting of ≥3.40% total C, 1.40W3.50% Si, 0.05W 0.20% Ce, 0.10W0.30% Ti, ≤0.040% S, ≤0.100% P and the balance essentially Fe or contg. further one or more among 0.50W3.00% Cu, 0.50W2.00% Mn, 0.10W 0.20% Sn and 0.05W0.10% Sb is used as a starting material for manufacturing a CV cast iron casting. The pig iron is remelted, inoculated, and poured in a desired mold to manufacture a casting. By using such pig iron contg. Ce spheroidizing graphite in iron and Ti hindering the spheroidizing, the CV cast iron casting can be manufactured very easily.
