Abstract

PURPOSE: To manufacture cast iron having superior strength, causing no blow hole and making slag easy to take out by adding a restricted amount of a silicon compound contg. calcium to gray cast iron having low carbon equiv.
CONSTITUTION: To the matrix of gray cast iron contg. 2.6W3.0% C, 2.4W3.0% Si and 3.4W4.0% Ce and having relatively low carbon equiv. is added 0.2W0.6% silicon compound contg. calcium such as calcium silicide. The resulting cast iron is provided with a uniform pearlite structure contg. fine graphite. It has high strength and prevents the occurrence of blow holes, and slag is easily taken out during melting. Thus, superior effects are produced.
