Abstract
PURPOSE: To improve inoculation effect and the soundness of castings by using an alloy for inoculation of cast iron comprising Si, Al, Ca, etc. of the specific composition and contg. below the specific value of O2.
CONSTITUTION: The composition of iron silicon alloy which is a base alloy is regulated to consist of 40W55wt% Si, 0.2W1.5 Al, 0.2W2 Ca or Ba and residual wt% Fe. In addition, the amount of O2 to be contained is made ≤100ppm. In this way, Al, which is the cause for dross, scum, pinholes, etc. is substituted with Ca or Ba, and the low oxidative effect due to the noncrystallization reaction of silicon alloy is positively utilized, whereby the formation of dross and pinholes is prevented and the inoculation characteristic is improved.
