Ratio of strength to chill depth of inoculated cast iron ( BI) is a key criterion of reflecting the suitability of inoculators to the high property cast iron casting with thin wall. 孕育铸铁的强度白口比BI是反映孕育剂对铸造薄壁高性能铸件适应程度的一项重要判据。
[ Results] Positive rate of anti-HBs was 77.22% in 237 inoculators. [结果]抗-HBs阳转率为77.22%。
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. 研究了含锑复合孕育剂对可锻铸铁白口倾向,退火石墨化速度,石墨的数量,大小及形状,基体组织以及机械性能的影响。
