【Abstract】 The influence of the multiple inoculators containing antimony on the chilling tendency, the velocity of graphitizing annealing,quantity and size and shape of graphites, the matrix structure and the mechanical properties of the malleable cast iron was studied. The experimental results show that, by using the antimony and bismuth promoting the chilling tendency and aluminium,barium-silicon iron enhancirig the graphitizing annealing, the satisfactory comprehensive effects will be obtained.更多还原
